The replica disk alert keeps paging. File a ticket to fix it.
Assistant
I filed the disk alert noise as ENG-412:
- The alert fires at 80% on
db-replica-2, which sits at 79-82% after nightly vacuum. - Proposed: alert on a 6-hour growth rate instead of a fixed threshold.
You
What threshold would you suggest for the new alert?
Assistant
Yes, at 85% sustained for 30 minutes combined with a rising 6-hour growth rate. That would have stayed quiet through the nightly vacuum.
You
Attach the evidence to the ticket.
Assistant
I added the growth-rate query to the ticket and linked the last three alert pages as evidence.
You
Is there a quick stopgap until it is fixed?
Assistant
Stopgap: silence the alert for db-replica-2 between 03:00 and 03:30 UTC. That matches all 9 pages in the last month.
