Enabled monitoring pmm-client and install pmm-server for test.
I do not see any metrics about PG replication, such as lag.
As well as metrics that relate to patroni.
Are they really not? I want to see the replication lag.
Is it configurable somehow?
How to fix it?
It is not possible to configure replication lag for nodes with the Operator yet. What would be your requirements here? We have it in our roadmap and it would be cool to understand the set of problems you want to solve with this.
As for monitoring - let me check with our PG experts if we have anything. @Umair_Shahid @charly.batista - is it possible to monitor replication lag in PMM?
is it possible to monitor postgresql replication lag in PMM?
From what I got from our experts - it is not possible right now.
