Description
Describe the bug
In certain environments, the dgraph_active_mutations_total monitoring metric disappears. During local debugging, I observed that this key only exists after a write request is triggered. This behavior might be unexpected as the metric disappears suddenly in production without any restarts.
To Reproduce
Steps to reproduce the behavior:
Deploy Dgraph version v24.0.2 in the local environment.
Monitor the dgraph_active_mutations_total metric.
By default, this key does not exist; it appears after a write request.
Expected behavior
The dgraph_active_mutations_total metric always exists.
Screenshots
Environment
- Version [e.g. v24.0.2]
