Prometheus Linux Jobs
Prometheus is the dominant open-source monitoring system for Linux and Kubernetes environments, part of the Cloud Native Computing Foundation alongside Kubernetes itself. Prometheus engineers instrument applications, design metrics pipelines, write PromQL queries, and build alerting rules that underpin the reliability of production Linux infrastructure.
Frequently Asked Questions
-
Prometheus collects time-series metrics from Linux hosts, Kubernetes nodes, and application exporters via a pull-based HTTP scraping model. It stores metrics locally and provides PromQL for querying and alerting. It is the standard monitoring backend for Kubernetes clusters and is widely used alongside Grafana for visualisation.
-
Prometheus roles almost always list Grafana for dashboarding, Alertmanager for alert routing, and Kubernetes for the deployment context. Experience with exporters (node exporter, kube-state-metrics, blackbox exporter) and PromQL query writing is expected. OpenTelemetry knowledge is increasingly listed for roles involving distributed tracing alongside metrics.
-
For large-scale deployments, Prometheus is typically run with Thanos or Cortex to provide long-term storage, global querying, and high availability. Mimir, developed by Grafana Labs, is a newer alternative to Cortex. Senior SRE and observability roles frequently require experience with one of these scaling solutions.
-
Not replaced, but complemented. OpenTelemetry standardises the collection of metrics, traces, and logs across languages and frameworks. Many teams use the OpenTelemetry Collector to gather data and then send metrics to Prometheus-compatible backends. Prometheus remains the dominant metrics storage and alerting layer.
