Bug reference: 16314
Logged by: Rajiv Ranjan
Email address: rajiv.mca08@gmail.com
PostgreSQL version: 9.6.0
Operating system: Red Hat Enterprise Linux Server release 7.6 (Maip)
Description:
Hi,
Currently, we are receiving a warning "Database Cache Hit Ratio
(%)(Warning)" from one of the monitoring tools.
This is not a bug in PostgreSQL. It is arguably a bug in your unnamed monitoring tool.
It is a dumb warning. The disk is there to be read from--doing so is not inherently a problem. Ignore the warning or disable it.
Are the queries you care about too slow because data is occasionally read from disk?
Cheers,
Jeff
