Syslog forwarding to Microsoft Sentinel

miguelMA — Mon, 09 Sep 2024 19:57:41 GMT

hello everyone.

seems we got a weird one here.

So we took the CEF format that the pdf guide says

heres the weird thing.

we truncated it to be under 2048 and the push was completed across the fleet

now the weird part

the sentinnel collector reports nothing from the physical hardware applicances

but does get everything from the VM's in azure.

The physical applicances using the same share profile/syslog groups ONLY the system logs are being "seen" in the tcp.

IF we take OUT the custom formating.

the sentinnel collector sees the traffic but of course in an unrecognized format.

Thoughts?

we running on 10.2.7-h3
