Hi, I have a job which is executed as a multiple instance.
Say I have this job named as 'JobA'. Say its 5 instances were run 1...10 like

JobA.1
JobA.2
.
.
JobA.10

My log gets cleared say after 3 runs of JobA, then I could see logs for last 3 as JobA.8, JobA.9, JobA.10.

Cant we see last 3 logs for every individual instance? Is there any setting we need to change to achieve this?

Unfortunately not, the purging was designed before multiinstance jobs and wasn't modified to account for "sharing" the same log file. You could switch to time-based purging in order to keep recent multi-instance runs.
