An Administrator’s Guide to Prometheus Monitoring

Scale your Prometheus monitoring efficiently and effectively.

Prometheus is a free and open-source monitoring tool popular with Kubernetes administrators due to its simple installation and native integration. Sponsored by SoundCloud, Prometheus became an incubating project of the Cloud Native Computing Foundation (CNCF) in 2016, graduating in 2018. Since then, the open-source community has come together to overcome its lack of high availability with Thanos and help it scale with Cortex.

It is easy to install Prometheus in a single Kubernetes cluster, but it is challenging to scale Prometheus in a multi-cluster enterprise environment with high availability requirements. As a committed member of the Prometheus community, OpsRamp has adopted Prometheus Cortex in the core of its platform to offer native compatibility.

OpsRamp helps Prometheus administrators with the enterprise scaling challenge by:

  • Importing and storing Prometheus metrics data to avoid the burden of managing dozens of local databases across Kubernetes clusters
  • Providing a modern and hosted visualization layer that natively supports PromQL for Prometheus and other integrations directly supported by OpsRamp
  • Leveraging state-of-the-art machine learning algorithms to ingest Prometheus alerts, cross-correlate with alerts from other supported OpsRamp integrations, and improve alerting accuracy
  • Bringing all of its platform’s features such as integrations with public clouds and runbook automation to offer a single pane of glass

As a sign of commitment to Prometheus technologies, we have created this guide to help the Prometheus user community better appreciate the Prometheus architecture, configuration, scaling, and query language.
