What are these Jira logs?

Question

I am trying to reclaim some space.  In folder var/log, I have the following logs:

-rw-r----- 1 root root 280980 Jan 21 2021 messages-20210121.xz
-rw-r----- 1 root root 287176 Feb 6 2021 messages-20210206.xz
-rw-r--r-- 1 root root 1046 Feb 12 2021 MAR-Client-Install-1613099248.log
-rw-r--r-- 1 root root 1046 Feb 13 2021 MAR-Client-Install-1613185648.log
-rw-r--r-- 1 root root 1046 Feb 14 2021 MAR-Client-Install-1613272047.log
-rw-r--r-- 1 root root 1046 Feb 15 2021 MAR-Client-Install-1613358448.log
-rw-r--r-- 1 root root 1046 Feb 16 2021 MAR-Client-Install-1613444846.log
-rw-r--r-- 1 root root 1046 Feb 17 2021 MAR-Client-Install-1613531246.log
-rw-r--r-- 1 root root 1046 Feb 20 2021 MAR-Client-Install-1613790445.log
-rw-r--r-- 1 root root 1046 Feb 21 2021 MAR-Client-Install-1613876847.log
-rw-r----- 1 root root 286484 Feb 22 2021 messages-20210222.xz
-rw-r--r-- 1 root root 1046 Feb 22 2021 MAR-Client-Install-1613963246.log
-rw-r--r-- 1 root root 1046 Feb 23 2021 MAR-Client-Install-1614049646.log
-rw-r--r-- 1 root root 1046 Feb 24 2021 MAR-Client-Install-1614136045.log

These go back to a year ago.  Are these needed?  Can they be deleted?

The call to delete them is yours, the same goes with the period you want to keep logs.

From experience we don't keep them more than 2 months.

All the best,

These are almost certainly not Jira logs.

Jira does not

* place logs in /var/log unless you reconfigure it manually
* normally run as root, which is the owner of these logs
* create logs called  MAR-client-install.  The format of the name is wrong, let alone the words in it!

I'd guess these are something to do with a "MAR Client", whatever that may be!
