Prometheus relabeling

Use IP address labels

Instead of __meta_pve_name, it is also possible to configure Prometheus to use the address provided by __meta_pve_ipv4 or __meta_pve_ipv4 for connections:

relabel_configs:
- replacement: ${1}:9273
  source_labels:
  - __meta_pve_ipv4
  target_label: __address__

Convert tags to custom labels

Tags of a node exposed by the __meta_pve_tags might be useful to build more complex configurations in Prometheus. As an example, an alert tag can be extracted to dine alerting routes based on the tag value.

Example:

Extract group and alert from a list of tags like this: __meta_pve_tags="alert:team-1,group:cluster-1,node:node-1"

relabel_configs:
- source_labels:
  - __meta_pve_tags
  regex: ".*group:([\w\-_]*)"
  target_label: "group"
  replacement: "${1}"
- source_labels:
  - __meta_pve_tags
  regex: ".*alert:([\w\-_]*)"
  target_label: "alert"
  replacement: "${1}"

Use the extracted alert label to set an Alertmanager route:

routes:
- receiver: "empty"
  matchers:
  - alert = muted
- receiver: "team-1"
  matchers:
  - alert = team-1
