The 11 best cloud monitoring tools, ranked for 2027

Q: Is CloudWatch enough for cloud monitoring?

If your estate is entirely AWS, CloudWatch is excellent and offers the deepest AWS service coverage of any tool. It stops at the AWS boundary, so multi-cloud and on-prem estates need additional tools. Its per-metric and per-GB charges compound across services and accounts, and default EC2 metrics arrive at 5-minute resolution unless you pay for detailed monitoring.

Q: What is the difference between cloud monitoring and observability?

Cloud monitoring tracks the health and performance of infrastructure and managed services through metrics, logs and alerts. Observability adds traces and the ability to interrogate failure modes you did not predict in advance. Most platforms in this list now do both, so the distinction is increasingly marketing as much as capability.

Q: Can one tool monitor AWS, Azure and GCP together?

Yes. Datadog, Dynatrace, New Relic, Grafana Cloud, LogicMonitor, Checkmk, Zabbix and Netdata all cover multiple providers from one surface. The native tools, CloudWatch and Azure Monitor, are single-provider by design. Coverage depth varies by service, so verify that your specific databases, queues and serverless platforms are supported before committing.

Q: Do I need an agent for cloud monitoring?

Not for everything. Provider-native service metrics such as CloudWatch metrics and Azure Monitor platform metrics need no agent at all. Agent-based tools (Netdata, Datadog, Dynatrace OneAgent, Checkmk, Zabbix) give deeper host, container and process visibility. The common production pattern is a hybrid: agentless coverage of managed services plus agent-based coverage of the hosts you control.

Q: Is open-source cloud monitoring a good idea?

Zabbix and the Prometheus, Grafana, Loki and Tempo stack are credible and widely deployed in production. Open source is a distribution model, not a price: you run and operate it yourself, and that operational cost is real. It suits teams with monitoring expertise and data-sovereignty requirements; commercial platforms win on time-to-value and built-in AI features.

Cloud monitoring fails in two predictable ways: a provider-native console that stops at the provider boundary, or an all-in-one suite whose bill grows with data volume instead of value. We ranked 11 tools on multi-cloud coverage, data resolution, alerting quality and pricing predictability, with the trade-offs stated plainly.

The 11 best cloud monitoring tools, ranked for 2027 product interface

Why this list exists

The two ways cloud monitoring fails

Most buyers arrive here after one of two experiences. Either they outgrew a provider-native console: CloudWatch or Azure Monitor works until the estate spans a second provider or an on-prem rack, and suddenly there are three dashboards and no single view. Or they got the bill from an all-in-one observability suite and discovered it scales with ingested gigabytes, host hours and add-on modules rather than with anything resembling value received.

What makes cloud monitoring a different problem

Cloud monitoring is also not the same problem as single-server or uptime monitoring. The estate is dynamic: autoscaling groups, managed databases, queues, serverless functions and Kubernetes nodes that live for minutes. A tool that polls a fixed host list once a minute will miss both the transient spike and the short-lived container that caused it.

What separates the best cloud monitoring tools

Three dimensions decide the outcome more than any feature checklist:

Coverage boundary. Does the tool natively monitor the providers and managed services you actually run, including hybrid and on-prem, or does it stop at one provider’s edge?
Pricing shape. Does the bill track estate size (per node, per host) or data volume (per GB, per metric, per indexed event)? Volume-based pricing punishes exactly the verbosity you want during an incident.
Resolution. Per-second collection catches the 3-second CPU burst that throttles an autoscaling workload; minute-scale polling averages it away.

How to model what these tools cost

We deliberately do not quote competitor list prices in this guide. Modular and usage-based pricing makes any single number misleading, and rates change. Instead we describe each vendor’s pricing shape and what makes the bill grow, and we link every official pricing page so you can model your own estate.

This page covers the generic multi-cloud intent; for provider-specific deep dives see our guides to AWS monitoring tools, Azure monitoring tools and hybrid cloud monitoring tools, or step up to the broader infrastructure monitoring tools ranking.

We assembled the shortlist from the tools practitioners actually compare in 2026: review aggregators such as PeerSpot’s cloud monitoring category, practitioner threads on r/sre, r/aws and r/devops, vendor documentation, and independent billing comparisons published this year. Every tool here monitors at least one major public cloud in production today; native provider tools are included because buyers realistically weigh them against third-party platforms.

Two criteria carry the most weight, each at 20 percent. Multi-cloud and hybrid coverage, because escaping the single-provider boundary is the main reason to buy a third-party tool at all. And pricing predictability, because bill shock is the most common complaint in every review corpus and Reddit thread we read. Resolution and alerting quality follow at 15 percent each: a dashboard that updates every minute and an alert engine that cries wolf are the two failures engineers notice first.

Vendor 01 / 11 · #netdata

Netdata

Per-second metrics, logs and OpenTelemetry traces from one open-source agent, with on-node ML anomaly detection and pricing that scales with nodes, not data.

Best for

Teams that want per-second visibility across cloud VMs, containers and Kubernetes without per-GB billing surprises
SRE and DevOps teams who want anomaly detection and root-cause hints out of the box, not hand-built dashboards
Organizations that want telemetry stored on their own infrastructure

Pricing

Per-node pricing: Netdata Cloud Business starts at $4.50/node/month on annual plans, and the per-node rate decreases as node count grows
Agents are open source (GPLv3+) and free; the Community plan is free for personal, non-commercial use with up to 5 active connected nodes
Not billed: metrics volume, Logs Monitoring (querying logs in place), users, data retention, containers
Logs Management and Traces are marked Free Preview on the current price list

Pros

Per-second metric collection on every node by default, the highest default resolution in this comparison (Datadog is 15 seconds; CloudWatch, Azure Monitor, Zabbix and Checkmk are minute-scale)
Thousands of auto-discovered metrics per node with zero configuration: services, containers, Kubernetes, disks, network
Unsupervised ML runs on the node itself, so anomaly detection adapts as infrastructure changes and raw telemetry never leaves the host
One agent collects metrics, logs (systemd-journal, Windows Event Log, macOS unified logs queried in place) and OpenTelemetry traces over OTLP
Multi-tier dbengine retains up to about 2 years of metrics on-node out of the box
The bill does not grow with metrics volume, users or retention

Where it falls short

Provider-managed services are collected through the providers’ own monitoring APIs (CloudWatch, Azure Monitor), so their resolution is what the provider publishes; per-second collection applies where the Netdata Agent runs
No cloud cost or FinOps module: Netdata monitors performance, not provider billing data, so pair it with a cost tool if spend visibility is a requirement
No cloud security posture management or workload security, an area where Datadog and Dynatrace run full product lines

Verdict

Netdata leads this list because it fixes the two failures buyers actually complain about: resolution and bill predictability. Per-second collection on every node catches the transient spikes minute-scale polling misses, and the bill grows with node count, not with how much telemetry you dare to keep. One open-source agent now covers metrics, logs and OpenTelemetry traces, with ML anomaly detection running where the data is born. The honest caveat: deep monitoring of provider-managed services still flows through the providers’ own APIs, and there is no FinOps module, so all-in-one suite buyers and cloud-cost teams should read the Datadog and CloudWatch cards too.

Vendor 02 / 11 · #datadog

Datadog

The broadest unified observability and security SaaS, with 700+ integrations spanning cloud infrastructure, APM, logs, RUM and security.

Best for

Scaling teams that want one vendor for metrics, logs, traces, RUM and security
Heterogeneous stacks needing the widest integration catalog
Teams with budget headroom that value time-to-value over cost control

Pricing

Modular per-product pricing: separate line items for infrastructure hosts, APM, logs ingestion and indexing, RUM sessions, synthetics and security
Infrastructure billed per host; logs per GB ingested and per indexed event; custom metrics per metric
Costs compound as more products are enabled and included allocations are exceeded; the most common complaint in reviews

Pros

Widest integration set on the market (700+), with deep AWS, Azure and GCP service coverage
Infrastructure, APM, logs, RUM, synthetics, CSPM and incident management share one tag model and UI
15-second default collection interval for standard integrations, finer than most competitors
Ranked #1 cloud monitoring software on PeerSpot by review volume (8.6 rating, 200+ reviews)
Strong out-of-the-box dashboards for AWS services such as Lambda, SQS and RDS

Cons

Costs compound fast once APM, logs and RUM are enabled together; multiple 2026 comparisons find New Relic and Grafana Cloud 3-5x cheaper at comparable scale
Modular pricing makes bill forecasting hard; custom metrics and log indexing allocations are frequent surprise charges
SaaS-only telemetry storage; data leaves your infrastructure

Verdict

Datadog is the strongest all-in-one commercial fit for multi-cloud monitoring. Native integrations cover essentially every AWS, Azure and GCP service, and the unified tag model across infrastructure, APM, logs and security is genuinely productive. PeerSpot reviewers rank it first in the category by volume. Its weakness for this topic is purely economic: the same breadth that makes it attractive is what makes the bill grow, and bill forecasting across modules is a job in itself. If budget discipline matters as much as breadth, model the full stack before signing.

Vendor 03 / 11 · #dynatrace

Dynatrace

Enterprise observability built around the Davis AI engine, with automatic discovery and causal root-cause analysis for cloud-native estates.

Best for

Large enterprises needing AI-driven root-cause analysis across complex cloud-native estates
Regulated organizations wanting SaaS or managed on-prem deployment
Teams that prefer a single annual commitment over per-product purchasing

Pricing

Commitment-based platform pricing: one annual commitment drawn down at rate-card prices across capabilities
Consumption units include host hours, Davis data units, log ingest and synthetic sessions
Larger commitments lower the rate; the model suits enterprises more than small teams

Pros

Davis AI performs automatic dependency discovery and causal root-cause analysis, not just anomaly flags
OneAgent auto-instruments applications, containers and cloud services with minimal configuration
Full-stack coverage: infrastructure, APM, logs, digital experience and security on one platform
Managed on-premises deployment option for regulated environments
Consistently named alongside Datadog as the enterprise APM leader in 2026 comparisons

Cons

The annual commitment model is a poor fit for small and mid-size teams or fast-changing workloads
Heaviest option in this list for smaller estates; overkill for straightforward cloud infrastructure monitoring
Davis is a centrally-trained expert system; teams that want anomaly models that adapt per node, with raw telemetry staying on the host, should weigh on-node ML approaches

Verdict

Dynatrace earns its place when automated root-cause analysis across a large, application-heavy cloud estate is the priority. OneAgent’s auto-instrumentation and the Davis engine are built for exactly that triage problem, and the managed on-prem option matters in regulated industries. The trade-off is commercial weight: the commitment model and platform footprint are sized for enterprises, and smaller teams will pay for capability they never switch on.

Vendor 04 / 11 · #newrelic

New Relic

Full-stack observability with consumption pricing, a generous free data allowance, strong APM and first-class OpenTelemetry support.

Best for

Growth-stage teams wanting Datadog-class breadth at lower cost
Teams standardizing on OpenTelemetry
Organizations that want APM-first observability with infrastructure included

Pricing

Consumption-based: billed per provisioned full-platform user plus per GB of data ingested
A free monthly ingest allowance includes full platform access
The bill grows with ingest volume (especially logs and high-cardinality metrics) and user count

Pros

Most generous free ingest allowance in the observability market with full platform access, per multiple 2026 comparisons
Strong APM with distributed tracing, plus infrastructure, logs, RUM and synthetics
First-class OpenTelemetry support
Consumption model is simpler to forecast than Datadog’s modular per-product pricing
Frequently recommended on Reddit as the like-for-like SaaS alternative when Datadog pricing kills the conversation

Cons

Consumption pricing still scales with ingest volume; logs and high-cardinality metrics drive the bill up
Practitioner complaints about the consumption model and limited access for non-users
Weaker dedicated security product line than Datadog

Verdict

New Relic is the best value-for-breadth ratio among the commercial SaaS platforms here. The free ingest allowance makes evaluation straightforward, APM is the center of gravity, and OpenTelemetry is a first-class citizen rather than a checkbox. The catch is the same physics as every usage-based platform: verbose logging and high-cardinality metrics turn into money. APM-led teams will find it a natural fit; pure infrastructure teams may find it heavier than needed.

Vendor 05 / 11 · #grafana

Grafana Cloud

Managed observability built on the open-source Grafana, Prometheus, Loki and Tempo projects, with the strongest open-standards ecosystem.

Best for

Teams already invested in Prometheus, Grafana dashboards or the OSS observability ecosystem
Engineering-led organizations comfortable assembling their own stack
Cost-sensitive teams that want commercial support for open standards

Pricing

Per-host-hour and per-container-hour pricing for infrastructure, plus usage-based pricing for metrics series, logs and traces
A free tier with monthly usage allowances and community support
A monthly platform fee on paid plans; the bill grows with active series, log volume and retention choices

Pros

Built on open standards: Prometheus, OpenTelemetry, Loki, Tempo; no lock-in on instrumentation
Best-in-class dashboarding and the largest dashboard and integration community
Independent 2026 billing analyses find it 3-5x cheaper than Datadog at comparable scale
A genuinely usable free tier with access to the full platform feature set

Cons

You assemble the stack: alerting rules, recording rules and dashboards are largely your own work versus turnkey platforms
Metric cardinality and series counts drive costs and need active management
No unified agent story comparable to Datadog or Netdata; multiple components to operate and correlate

Verdict

Grafana Cloud is the pick when open standards and cost control outrank turnkey convenience. The self-hosted path removes licence cost entirely, and the managed cloud prices competitively at scale. The honest cost is labor: someone on your team owns the recording rules, the cardinality budget and the dashboard library. Teams that want the platform to do that work for them should look at Netdata or Datadog instead.

Vendor 06 / 11 · #cloudwatch

Amazon CloudWatch

AWS-native monitoring for AWS resources and applications, with metrics, logs, alarms and dashboards built into the console and the AWS bill.

Best for

AWS-only teams that want zero additional vendor and IAM-integrated monitoring
Workloads where AWS service metrics (Lambda, ECS, RDS) are the primary concern
Teams already deep in AWS tooling and billing

Pricing

Usage-based: per metric stored, per GB of logs ingested and stored, per alarm, per dashboard, per API request
Volume-tiered metric pricing; high-resolution metrics and cross-account features cost more
No license; costs appear on the AWS bill, which makes them easy to miss

Pros

Deepest native AWS service coverage of any tool, with no agent needed for service metrics
Tight IAM, billing and console integration; zero procurement friction for AWS shops
Mature alarms, EventBridge integration and the Logs Insights query language
The default practitioners start with before evaluating third-party tools

Cons

AWS-only: multi-cloud and on-prem estates need additional tools, creating dashboard sprawl
Pricing is widely called opaque; per-metric and per-GB charges compound across services and accounts
Default metric resolution is 1 minute (5-minute basic for EC2), too coarse for transient spikes
Practitioners on r/aws actively seek friendlier alternatives for dashboards and usability

Verdict

CloudWatch is the best possible answer if and only if your estate is entirely AWS. No third party will ever match its coverage of AWS service internals, and the procurement cost is zero. The boundary is the problem: it stops where AWS stops, its default resolution misses short-lived spikes, and the charges arrive buried in the AWS bill. For the multi-cloud intent behind this search, it is a partial answer by design.

Vendor 07 / 11 · #azuremonitor

Azure Monitor

Microsoft’s native monitoring for Azure resources, VMs and Kubernetes, with platform metrics, Log Analytics and managed Prometheus.

Best for

Azure-centric organizations that want native integration with Azure services and Arc
Teams standardizing on managed Prometheus inside Azure
Enterprises with Microsoft EA agreements

Pricing

Platform metrics for standard Azure resource metrics ingested at no charge per billing account
Log Analytics workspace billed per GB ingested and per GB retained beyond the included allowance
Managed Prometheus billed per samples ingested, with retention included

Pros

Native, no-charge platform metrics for Azure resources at 1-minute resolution
Managed Prometheus and managed Grafana give an open-standards path inside Azure
Log Analytics KQL is a powerful query language for logs and metrics
Azure Arc extends monitoring to on-prem and other clouds from the same surface

Cons

Azure-first: like CloudWatch, it is a partial answer for multi-cloud estates
Log Analytics per-GB ingest pricing makes verbose workloads expensive; sampling and filtering needed
The configuration surface (workspaces, diagnostic settings, data collection rules) is complex to set up correctly

Verdict

Azure Monitor is excellent inside Azure, and the managed Prometheus path is a credible open-standards route. Arc genuinely stretches it toward hybrid estates, though the center of gravity never leaves Azure. The same boundary logic as CloudWatch applies: if your estate is mostly Azure it belongs on the shortlist, and if it is not, it is one pane among several.

Vendor 08 / 11 · #logicmonitor

LogicMonitor

SaaS hybrid infrastructure observability with automated device discovery and tiered per-unit packages, popular with enterprises and MSPs.

Best for

Enterprises and MSPs monitoring large hybrid estates (data center plus cloud)
Teams that want automated discovery and low-maintenance collection
Organizations wanting bundled pricing instead of per-product add-ons

Pricing

Tiered platform packages priced per hybrid unit, a normalized capacity unit across devices, VMs, containers and cloud resources
Packages bundle most observability features per tier rather than selling them as add-ons
The bill grows with monitored resource count within the hybrid-unit model; enterprise-oriented quotes

Pros

Automated discovery and monitoring of hybrid infrastructure: devices, VMs, containers and cloud accounts
Bundled tier pricing is more predictable than Datadog’s modular model
Strong network and infrastructure monitoring heritage with AI anomaly detection (Edwin AI)
Digital experience monitoring via the Catchpoint integration, including DNS, BGP and CDN visibility

Cons

Hybrid-unit pricing is opaque until quoted; entry cost is high for small teams
APM and application telemetry are less deep than Datadog, New Relic or Dynatrace
SaaS-only telemetry storage

Verdict

LogicMonitor is the enterprise hybrid-estate candidate: strong discovery across data center and cloud, network depth most SaaS platforms lack, and a bundled pricing shape that is easier to forecast than per-module billing. The opacity works the other way before signature, since hybrid units need a quote to price. Application-heavy teams will find the APM layer thinner than the leaders; infrastructure-led teams will not miss it.

Vendor 09 / 11 · #checkmk

Checkmk

Infrastructure-centric monitoring with a single agent covering servers, networks, cloud accounts and applications, on-prem or SaaS.

Best for

Infrastructure and ops teams monitoring mixed estates of servers, network devices and cloud VMs
Organizations wanting on-premises monitoring with strong vendor support
Teams replacing Nagios or Zabbix-class tools with a more automated alternative

Pricing

Open-core: the Raw edition is open source and self-hosted; commercial editions (including managed SaaS) are licensed per host or per service count
No per-GB ingest pricing; costs track estate size rather than data volume
Edition upgrades add automation and enterprise features

Pros

A single agent collects CPU, memory, disk, processes and connections, plus plugins for databases and applications
Cloud monitoring for AWS, Azure and GCP alongside on-prem hosts, deployed on-prem or as SaaS
Rated highest among infrastructure tools for ease of setup and support quality in Sirius Open Source’s analysis
2,000+ prebuilt check plugins with strong alerting and notification rules

Cons

Weak on real-time analytics and AI integration versus modern platforms, per the same Sirius analysis
A 1-minute default check interval misses transient spikes
Infrastructure-centric: APM, tracing and RUM are not core capabilities

Verdict

Checkmk is the disciplined choice for the infrastructure layer of a hybrid estate, especially where on-prem servers still matter and support quality is weighted heavily. Setup automation and the plugin library are genuinely good. It does not pretend to be an observability platform: there is no meaningful tracing or RUM story, and the analytics layer is a generation behind. Buy it for solid host and network monitoring, not for a platform bet.

Vendor 10 / 11 · #zabbix

Zabbix

Mature open-source monitoring with native templates for AWS, Azure and GCP, self-hosted on your own infrastructure.

Best for

Teams with in-house monitoring expertise that want full control and no license fees
Organizations with strict data-sovereignty or air-gapped requirements
Estates mixing SNMP network devices, servers and cloud accounts

Pricing

Open source and self-hosted: no per-host or per-GB license fees, you operate it yourself
Vendor revenue comes from optional support subscriptions and consulting
The real cost is operational: server infrastructure, upgrades, template and trigger maintenance

Pros

Native auto-discovery and monitoring templates for AWS (EC2, EBS, RDS, S3), Azure and GCP
Extremely flexible: custom items, triggers and escalations backed by 20+ years of community templates
No data-volume billing of any kind; costs do not grow with metric count
Large active community and a long production track record

Cons

High operational overhead: server maintenance, template authoring and trigger tuning are your job
A 1-minute default polling interval misses transient spikes
Modern UX, dashboards and AI anomaly detection lag commercial platforms; practitioners pair it with Grafana for visualization

Verdict

Zabbix offers genuine cloud coverage through official templates and unbeatable licence economics. Nothing in this list gives you more control per dollar. The trade is everything commercial platforms sell: your team owns the server, the templates, the trigger tuning and the dashboards, and the analytics layer feels its age. For expert teams with sovereignty requirements it remains a serious answer; for lean teams it becomes a second job.

Vendor 11 / 11 · #site24x7

Site24x7

Affordable all-in-one SaaS from ManageEngine covering websites, servers, cloud, Kubernetes, logs and network, priced per monitor.

Best for

Small and mid-size businesses wanting broad coverage at low cost
Teams needing website and uptime monitoring plus server and cloud monitoring in one product
Organizations without a dedicated observability platform team

Pricing

Per-monitor licensing: each website, server, cloud resource or check consumes monitor units from the plan allowance
Tiered plans with add-on monitor packs; no per-user fees
The bill grows with the number of monitored resources and add-ons

Pros

Broadest coverage-per-dollar in this list: website, server, cloud, Kubernetes, log and network monitoring in one SaaS
Significantly more affordable than Datadog, New Relic or LogicMonitor per TechRadar’s review, with no per-user fees
An on-premises poller option monitors private resources behind firewalls
Strong synthetic and end-user experience heritage from ManageEngine

Cons

Per-monitor licensing gets fiddly at scale; counting what consumes a monitor unit is a planning exercise
Analytics depth, APM and AI features trail Datadog, Dynatrace and New Relic
Enterprise-scale estates typically outgrow its data and scale ceilings

Verdict

Site24x7 is the budget answer that still covers the breadth: uptime, servers, cloud and logs in one product a small team can run without a platform engineer. The per-monitor unit model is its main friction, since forecasting means counting resources in the vendor’s units rather than your own. Enterprises shortlist it as the cost benchmark against LogicMonitor and Datadog, and larger estates tend to outgrow it; many SMBs never do.

Frequently asked questions

What are the best cloud monitoring tools in 2027?

Our shortlist: Netdata, Datadog, Dynatrace, New Relic, Grafana Cloud, Amazon CloudWatch, Azure Monitor, LogicMonitor, Checkmk, Zabbix and Site24x7. The right pick depends on your estate (single-cloud versus multi-cloud), team size and pricing tolerance. Netdata leads for per-second resolution and predictable per-node pricing, Datadog for integration breadth, and the native tools only make sense for single-provider estates.

Is CloudWatch enough for cloud monitoring?

How much do cloud monitoring tools cost?

Three pricing shapes dominate: per-node (Netdata, Checkmk), per-GB or usage-based (Datadog logs, New Relic, CloudWatch, Azure Monitor), and per-unit packages (LogicMonitor hybrid units, Site24x7 monitors). Usage-based bills grow with ingest volume and cardinality; per-node bills grow with estate size and are easier to forecast. Open source (Zabbix, a self-hosted Grafana stack, Netdata agents) removes licence cost but not operational cost. We deliberately quote no competitor list prices here; every card links the vendor’s official pricing page so you can model your own estate.

What is the difference between cloud monitoring and observability?

Can one tool monitor AWS, Azure and GCP together?

Why is Datadog so expensive, and what are cheaper alternatives?

Datadog prices modularly: infrastructure, APM, logs, RUM and security are billed separately, and the costs compound once several modules are enabled and included allocations are exceeded. Independent 2026 comparisons find New Relic and Grafana Cloud 3-5x cheaper at comparable scale. Cheaper alternatives worth evaluating are New Relic (consumption with a free allowance), Grafana Cloud (per-host-hour), Netdata (per-node) and Zabbix (self-hosted open source).

Do I need an agent for cloud monitoring?

What collection interval should cloud monitoring use?

Per-second collection, Netdata’s default, catches the transient spikes that throttle autoscaling workloads and vanish from minute-scale averages. Intervals from 15 seconds (Datadog’s default) to 1 minute (Zabbix, Checkmk, CloudWatch standard, Azure Monitor) are adequate for capacity planning and routine alerting. On usage-based platforms finer resolution costs more; on Netdata it is the default with no volume charge.
