[HTCondor-users] How history file rotation works in HTCondor

[Maria Alandes Pradillo <Maria.Alandes.Pradillo@xxxxxxx>]

Hi,

 

I’m trying to understand how HTCondor rotates history files. I’m using them for our accounting and I’m trying to validate accounting data from different accounting systems (all using HTCondor history files one way or another), against the “raw” history files themselves.

 

Some examples from our testing pool where schedulers are used infrequently:

-rw-r--r--. 1 condor condor 215779 Apr 15 13:04 history.20250526T115455

-rw-r--r--. 1 condor condor  12979 May 26 12:43 history.20250527T140056

-rw-r--r--. 1 condor condor  18276 May 27 16:27 history.20250611T161637

 

My understanding is that the name of the history file is the moment when it’s rotated.

 

In our production pool, where there are a lot of jobs, history files are rotated basically every day at midnight. So what’s the criteria to rotate a file? Is this configured somewhere?

 

Thanks a lot,

Maria
