Description

Describe the problem/challenge you have Currently it is hard to see how many backup jobs are running.

Describe the solution you'd like Expose a velero_backup_active_total metric. An integer value starting at 0.

Anything else you would like to add: Maybe the pods running the actual backup could report their progress too?

Environment:

  • Velero version (use velero version): v1.2.0
  • Kubernetes version (use kubectl version): v1.15.6
  • Kubernetes installer & version: v1.15.3
  • Cloud provider or hardware configuration: on-premise
  • OS (e.g. from /etc/os-release): Ubuntu 18.04

Contributor guide

Research direction
Look at existing metrics implementation in the codebase, specifically how other metrics like `velero backup total` are defined and registered. Add a new gauge metric `velero backup active total` that increments when a backup starts and decrements when it finishes. Ensure thread safety and proper naming.
