Consider a seemingly working example where the parent-id has been configured incorrectly within the processes plugin sampler but somehow has been picked up as working by a pre GA4.10 netprobe.
Example process details
sybase 14098 1 0 Feb04 ? 00:00:00 /bin/sh ./RUN_CENTOS7
sybase 14099 14098 1 Feb04 ? 08:04:22 /opt/sybase/ASE-16_0/bin/dataserver -d/opt/sybase/data/master.dat -e/opt/sybase/ASE-16_0/install/CENTOS7.log -c/opt/sybase/ASE-16_0/CENTOS7.cfg -M/opt/sybase/ASE-16_0 -N/opt/sybase/ASE-16_0/sysam/CENTOS7.properties -i/opt/sybase -sCENTOS7
Incorrect configuration (highlighted in red) - but plugin displays the instance as running.
If the NetProbe is ugpraded to GA4.10 (or above) this now fails.
This is because the processes plugin has been now been corrected to pick up the correct string according to the Rule specified on this.
whilst /bin is part of the process string - the configuration option chosen was Exact.
The answer would be to correct the configuration Search String
The code change can be found in the release notes for GA4.10.
