nrpe checks fail after adding relabel_configs in prometheus #157

Open ahmadfsbd1 opened 1 week ago

ahmadfsbd1 commented 1 week ago

Bug Description

After adding relabel_configs in cos-prometheus through prometheus-scrape-config-k8s charm, the nrpe checks fail. When the relabel_config is removed, the nrpe checks and alerts will work as expected.

To Reproduce

  1. Deploy the standard cos
  2. Deploy nrpe charm in a separate model with relation to cos-proxy forwarding to cos-prometheus
  3. Add the relabel_config to the cos-prometheus using the prometheus-scrape-config-k8s-charm. relabel_configs: |-
    • target_label: 'alerting_system' replacement: 'nfvi-cos'
    • target_label: 'site_identifier' replacement: 'site1'
  4. Observe that after the prometheus has resstarted and settled, the nrpe checks are failing.
