Regex to extract two strings from log and make as field


Log - (given 2 lines for example)

2017/02/21 03:46:12.119-0800 [http-bio-8480-exec-3] C3AF4B3F9C2E40D2006D1513C81191A6.pppxwbtect014 INFO  c.e.c.w.b.r.ShirtsSaleResource -  #xHoster#  #**res_ShirtServiceTosite**#  ShirtsSaleResource.getLossier  , URI ->  /{1856659}  , Time taken to get JSON -> **58** milliseconds

Expected output :

res_ShirtServiceToSite            58
res_CmppToShirtService            178

I tried :

index=app source=/var/log* "#xHoster#" | rex field=_raw res_(?.*)# | rex field=_raw .\-\>\s(?.*)\smilliseconds |table ptype,ptime

How about this:

rex field=_raw "(?res_[^*]+)" | rex field=_raw "\*(?\d+)"
0 Karma


How about this

index=app source=/var/log* "#xHoster#" 
| rex field=_raw  "#(?<ptype>res_[^#]+)#.+\-\>\s*(?<ptime>\d+)\s*milliseconds" 
| table ptype ptime

I came up with \*\*(?<ptype>res_[^\*]+)\*\*.*?\*\*(?<ptime>\d+)\*\*
