How to split access.log data

[slipinski]

Hello Splunkers,

I've got a problem with data splitting. I would like to split data into separate lines.

Please take a look at my data:

I want to have data split like below:

10.62.19.11 - - [03/Mar/2021:12:49:02 +0100] type:once,startTimestamp:1614772142364,endTimestamp:8999999999000},serviceDefinition:{descriptor:{label:,desc:},dests:[{destId:virtual.46.0.33,destName:}],groupOrder:1,profileId:7637a321-8628-47d3-92e8-5fd85b54aa6b,skipReuseJoinId:true,routing:p2mp,srcId:virtual.96.0.58,tags:[LastOnAirId:null,EmerOnAirId:null],type:connection,force:true

10.62.19.11 - - [03/Mar/2021:12:49:02 +0100] 
type:once,startTimestamp:1614772142364,endTimestamp:8999999999000},serviceDefinition:{descriptor:{label:,desc:},dests:[{destId:virtual.46.0.3,destName:}],groupOrder:1,profileId:7637a321-8628-47d3-92e8-5fd85b54aa6b,skipReuseJoinId:true,routing:p2mp,srcId:virtual.96.0.39,tags:[LastOnAirId:null,EmerOnAirId:null],type:connection,force:true

I suppose I need to use mvexpand in combination with static regex,  but I cannot find correct formula. Could you help please.

Try adding this to the relevant stanza of props.conf:

LINE_BREAKER = ()\d\d\.\d\d\.\d\d\.\d\d\s

This should properly split events on newly-indexed data.  It won't change what's already indexed.

hi @slipinski,

Try this:

| rex "^(?<field1>.*\d{4}\])\s" 
| rex "{scheduleInfo:{(?<field2>.+)}}\]}}" 
| eval field2=split(field2, "}},{scheduleInfo:{") 
| mvexpand field2 
| strcat field1 " " field2 newfield

If this reply helps you, an upvote/like would be appreciated.

Hi manjunathmeti,

Thanks for your effort. 

Your query extracts field1 correctly, but field2 is empty.  No idea why.
