I have several Cisco FTD devices (managed by Cisco FMC) that are sending syslog messages to splunk. Here is the format....
<164>Sep 19 2021 13:26:27 ftdv-b-int : %FTD-4-313005: No matching connection for ICMP error message: icmp src inside_Mgmt:10.0.20.238 dst inside_Legacy_Server:192.168.0.94 (type 3, code 3) on inside_Mgmt interface. Original IP payload: udp src 192.168.0.94/53 dst 10.0.20.238/12055.
The time is in UTC.... is there a way to convert this time to local when I pull the records in so I can do alerting, etc. on these records?
Splunk will convert the time zone for you. You just need to tell it what time zone the event occurs in. Do that by specifying TZ = UTC in props.conf for the appropriate sourcetype.
I'd be remiss if I missed this opportunity to point out that one should not send syslog directly to a Splunk TCP or UDP port. Instead, send it to a dedicated syslog server and forward it to Splunk or use Splunk Connect for Syslog.
