Silencing on Netdata

Misconfigured Alert Detection: Tuning Made Easy

Tue, 28 Apr 2026 00:00:00 +0000

Netdata ships with hundreds of stock alerts. They cover a wide range of infrastructure conditions and they’re designed with sensible defaults. But “sensible defaults” and “correct for your environment” are not the same thing. A CPU threshold that’s perfectly reasonable for a build server might generate constant noise on a machine running batch jobs. An alert that’s critical for production might be irrelevant in staging, where it fires daily and everyone ignores it.

Smarter Alerts: Test, Review & Preview Schedules

Thu, 16 Apr 2026 00:00:00 +0000

Alert fatigue usually isn’t caused by one thing. It’s the accumulation of thresholds that are slightly too sensitive, alerts that fire during known maintenance windows, and historical patterns that nobody has the tools to review easily. Fixing it requires better visibility into how alerts actually behave over time, and a way to test changes before they hit production.

We’ve shipped three improvements to alerting in Netdata that address different parts of this problem: the ability to evaluate alert definitions against historical data before deploying them, a timeline view of alert transitions, and a schedule preview for recurring silencing rules.

Prometheus Alertmanager: Noise Reduction Rules

Fri, 22 Aug 2025 00:00:00 +0000

It’s 3 AM, and a torrent of PagerDuty notifications floods your phone. A single network partition has triggered a cascade, making every service instance that can’t reach the database fire its own individual alert. You’re drowning in hundreds of notifications, all pointing to the same root cause. This is alert fatigue, a critical problem for any SRE or on-call engineer. When you’re constantly bombarded with low-signal noise, you risk becoming desensitized, potentially overlooking the one critical alert that signals a major incident.

How To Mute Alerts During Maintenance Windows

Thu, 03 Nov 2022 00:00:00 +0000

The health management APIs in Netdata allows teams to eliminate unnecessary alerting during scheduled maintenance, testing, auto scaling events, and instance reboots.

For all SREs, it is absolutely crucial to filter out expected events during maintenance windows and quickly pinpoint critical issues in your infrastructure. Every minute is crucial while dealing with troubleshooting issues and any distractions that may hijack the troubleshooting process should be subdued. The health management APIs in Netdata allows teams to eliminate unnecessary alerting during scheduled maintenance, testing, auto scaling events, and instance reboots.

Release 1.16.0: Smarter binaries and built-in TLS

Fri, 19 Jul 2019 00:00:00 +0000

We’re excited to launch release v1.16.0 of the open-source Netdata monitoring agent, which delivers real-time health monitoring and performance troubleshooting to nearly any system or application.

This release also contains 40 bug fixes, 31 improvements, and 20 documentation updates—if you’d like to see the full list, check out the full release notes.

Details aside, I know people are going to be most curious about the big changes we’ve just delivered to Netdata—let’s dive in.
