Hi,
We are asked to have key monitoring or alerting added to our postgres
database. And I am thinking of metrics like blocked transactions, Max
used transaction Ids, Max Active session threshold, Deadlock, Long
running query, replica lag, buffer cache hit ratio, read/write IOPS or
latency etc. I have below questions
1)Below are some which i tried writing, can you please let me know if
these are accurate?
2)How should we be writing the alerting query for deadlock, max used
transaction ids, read/write IOPS and latency?
3)Are there any docs available which have these sample sql queries on
the pg_* table for these critical alerts which we can easily configure
through any tool?
4)Any other alerts which we should be really having?
Somewhere to start:
