Alternatives to Prometheus
The metrics collection standard
Prometheus ranks #9 of 9 in Infrastructure monitoring, with an Alt Score of 78. It is licensed under Apache-2.0, free and available on Linux and Web. 9 of 10 checklist rows are verified against a public source.
DevOps and SRE teams running cloud-native infrastructure, especially Kubernetes environments, who need reliable metrics-based monitoring and alerting.
A time-series database with a dimensional data model (metric names plus key-value labels) for storing metrics. PromQL lets you query, aggregate, and transform that data for dashboards and analysis. Rule-based alerting evaluates PromQL expressions and forwards firing alerts to a separate Alertmanager component, which handles routing, grouping, and silencing.
Prometheus periodically scrapes (pulls) metrics over HTTP from instrumented applications and exporters, storing them locally as time series. You query this data with PromQL for dashboards or define alerting rules that push notifications through Alertmanager when thresholds are breached.
