Hi cyberportnoc,
check using a larger time period, often the problem is in differences in timestamp.

i found the reason in the recorded video case,
because the host use the same host name as another host, icnetwork01
so the file actually is icnetwork01 which exist in the list

[cyberportnoc]

after troubleshooting , i found the reasons that no log in these hosts,

some reasons that log file are locked by another process
,and some are misconfiguration of rsyslog.conf

Hi cyberportnoc,
Temporarly send your syslogs to a test index for a little period and search on this index, in this way you can be sure that you're receiving logs.
If there aren't there's a different problem to debug.
