/var directory Filling up

Hi Everyone,

Recently my /var directory in LTM is getting filled up and currently at 86%. Most of the space is occupied by arg_ex_out file ( Around 3Gigs ). Wanted to know if i can remove the contents of the file and if it causes any impact. It seems to be increasing 20MB/day

-rw-r--r--.   1 root  root  3242619992 Jun 10 13:39 arg_ex_out

Any Help would be appreciated.

arg_ex_out

    there are two K articles on this suggesting they come from external monitors

    this one explains how to deal with it: https://my.f5.com/manage/s/article/K14484554

      Yeah, F5 Engineers suggested this option and another engineer suggested the below 

             To remove:
      a. Login to BIGIP CLI.
      b. Enter command
      bash
      cd /var/log
      rm arg_ex_out

      But before following any of these steps , we wanted to make sure that removing this log file would not cause any impact or outage

        have you tried this by now? if so can you share the result.

         

        if you are still waiting i would say contact the F5 engineers (support) about this to be sure.

    Are the contents log entries, can you figure out what is writing to that file based on the contents? If not you can use the lsof command from the bash shell to determine what process is writing to that file.
