I just discovered that on one of my systems journald only retains log<br>
entries for about 10 days:<br>
<br>
# journalctl | head -1<br>
-- Logs begin at Wed 2020-11-04 15:57:13 UTC, end at Sat 2020-11-14 09:28:19 UTC. --<br>
<br>
I do not understand what could cause this, because I have no retention<br>
limit configured, and the logs take up way less space than I have<br>
reserved:<br>
<br>
# journalctl --disk-usage<br>
Archived and active journals take up 320.0M in the file system.<br>
<br>
# journalctl > alllogs<br>
# ls -lh alllogs <br>
-rw-r--r-- 1 root root 27M Nov 14 09:24 alllogs<br></blockquote><div><br></div><div>That just shows the 'MESSAGE' field -- it does not show any other fields that each entry will have stored, such as the unit name which generated the message; the program's command line; and apparently even the original unparsed packet that was received through /dev/log.
