How Can I Filter Metric Data?
During the Helm installation, you can pass in a
values.yaml as a parameter.
values.yaml you can:
How Do I Monitor Prometheus Metric Endpoints?
Many Kubernetes components and applications expose metrics in the Prometheus format via HTTP endpoints. The Wavefront Collector natively supports discovering such endpoints and collecting metrics from them. The Collector listens for the addition of pods within a Kubernetes cluster, and can automatically start collecting the prometheus metrics from pods by:
- Adding specific annotations on a pod to inform the Collector to start collecting metrics from it.
- Configuring static discovery rules to identify pods by labels, namespaces or image names and information on how to collect metrics from the pods.
See the auto discovery documentation for details.
How Do I Monitor Popular Third-Party Applications?
The Wavefront Collector supports monitoring over 20 popular applications such as Redis, Memcached, Postgres, MongoDB etc. Use static discovery rules to monitor these applications.
