How should we monitor our applications running under Kubernetes?
We recommend using a combination of Prometheus and Grafana custom dashboards.
How should we monitor our applications running under Kubernetes? Our internal applications generate logs and export metrics. Is it possible to provide a dashboard where these are displayed?
In the past, we’ve used Sumologic, CloudWatch Logs and Datadog Logs to aggregate logs from all Kubernetes pods. For self-hosted alternatives, we would rollout EFK (ElasticSearch, Fluentd and Kibana) to aggregate logs.
We do not recommend using a log aggregation framework in place of a metrics framework. While some systems try to do this (e.g. Sumologic), we prefer purpose-built tools. So we recommend running both a metrics-based platform in addition to a text/log based platform.
For metrics, we suggest using Prometheus Exporters API combined with Grafana for visualization.
We document our Prometheus/Grafana approach here:
