I dont see your post - what I am stuck with is whenever the date changes on that log example: _[18/Aug/2014:09:40:39 -0400]_ _[20/Aug/2014:11:40:39 -0104]_ _[19/Aug/2014:08:40:39 -0500]_ the filter will not match it On Monday, August 18, 2014 1:53:37 PM UTC-4, vitaly wrote: > On Monday, August 18, 2014 9:57:41 AM UTC-4, Kevin M wrote: > > > Could someone help me write a grok filter for this log real quick here is > > what the log looks like: > > > > Aug 18 09:40:39 server01 webmin\_log: 172.16.16.96 - username _[18/Aug/2014:09:40:39 > > -0400]_ "GET /right.cgi?open=system&open=status HTTP/1.1" 200 3228 > > > > here is what I have so far: > > > > match =\> [ "message", "%{SYSLOGTIMESTAMP:timestamp} %{WORD:Server} > > webmin\_log: %{IP:IP\_Address} - %{USERNAME:username} \*[ stuck at this > > middle part [18/Aug/2014:09:40:39 -0400] \*] "%{WORD:method} > > %{URIPATHPARAM:request} HTTP/1.1 %{NUMBER:bytes} %{NUMBER:duration} > > It is just a sequence of regular expressions catching fields one by one. > Look, e.g at my post. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
