Hi, my F5 ASM gets some realy huge requests, headers and other fields generating events with more than 64k characters. When that happen, the F5 Big IP breaks the event and when that gets into Splunk it's not recognized as an ASM event, because it's beginning doesn't have the string expected by the application.
Have anyone had the same problem? How do I configure Splunk to get that event correctly parsed and concatenated?
looked at the add-on and seems like no TRUNCATE value is set, meaning it will truncate events longer than 10000 bytes, default value for this configuration.
try and set TRUNCATE in props.conf under the matching sourcetype stanza in the add-on
create a new local folder in the TA, create props.conf file and add the relevant stanza and a high value for TRUNCATE
