The shortlist was assembled from three sources: HashiCorp’s own monitoring documentation (which names Prometheus, Grafana, Datadog, and Telegraf), HashiCorp’s technology partner directory (Netdata, Zabbix, Dynatrace, Sysdig), and tools with documented, maintained Consul integrations (New Relic, Instana, Elastic). Tools with no real Consul integration were excluded, however strong their general monitoring story.
The two heaviest criteria are Consul-specific coverage (25%) and metric granularity (20%), because they are what separate a genuine Consul monitor from a generic infrastructure dashboard. Alerting and deployment overhead each carry 15% - pre-built alert rules and zero-config collectors decide how long it takes to be protected, not just observed. Cost predictability (15%) reflects how the bill scales with fleet growth, and ecosystem breadth (10%) credits logs, traces, and integrations around the mesh.
