regex/grok patterns for BigIP Logs

Hi

 

I'm ingesting logs into the ELK stack. quite nice.

 

Only problem is i'm having to write the regex patterns by hand for each log type (tmm/secure/user).

 

Is there a wiki that lists:

 

1. log syntax (e.g. fields used for TMM log and field order in the log)
2. regexes for these formats

I'd be really pleased if there was even just a page that listed (1) log syntax for each type

 

I've seen in the discussions here that log formats also change between versions... any ideas on how often this happens...?
