Title mk_postgres, postgres_instances: fix plugin output for older operating systems
Date Jun 14, 2019
Checkmk Edition Checkmk Raw (CRE)
Checkmk Version 1.5.0p19 1.6.0b3 2.0.0i1
Level Trivial Change
Class Bug Fix
Compatibility Incompatible - Manual interaction might be required

mk_postgres used the pgrep command to find the running PostgreSQL instances. Unfortunately, version 1.5.0p3 added a command line argument that is not supported on older operating systems like e.g. SLES 11, but only on newer ones like e.g. SLES 12. As a result Checkmk did not find any PostgreSQL instances on older operating systems.

To resolve the issue, the fixed version of the mk_postgres plugin has to be deployed on the affected hosts.
