some of my events are 110,000+ characters long. I tried TRUNCATE=0 and MAX_EVENTS=0 to no effect. some of my events log from the middle and others do not log in the end. Some are logged just fine. Examples below,

Im not sure indexed extractions are what you want here... Try adding the following and test this..

SHOULD_LINEMERGE = true
KV_MODE = json
BREAK_ONLY_BEFORE = ^\d\d\-\d\d\-\d\d
TIME_PREFIX = ^
MAX_TIMESTAMP_LOOKAHEAD = 25

This is assuming your events starts with the date and time

Hi @esix_splunk, the timestamp is not the start of the event. My event is typically starts with a """ {"building": """ like this,

{"building": false, "changeSet": {"items": [{"comment": "Revert \"set pos field can be overrided by logGroup dynamically \"\n", "paths": [{"editType": "edit", "file": "src/datamodel/ComponentData.php" }], "author": {"absoluteUrl": "http://thefactory.corp.xxx.com:9999/jenkins/user/prajakta", "fullName": "prajakta"}, "timestamp": 1432177477000, "id": "5f428d3cde806ec296538023dae94ae694bca747", "com mitId": "5f428d3cde806ec296538023dae94ae694bca747", "msg": "Revert \"set pos field can be overrided by logGroup dynamically \"", "date": "2015-05-21T03:04:37+0000 -0700", "affectedPaths": ["src/datamo del/ComponentData.php"]}], "kind": "git"}, "builtOn": "rhel6-gq1-factory-slave-029.infra", "description": null, ...


And jenkinsTimestamp is the timestamp I want splunk to pick up. and hence the
TIMEFORMAT = %s%3N
TIME
PREFIX = jenkinsTimestamp
I tried KVMODE=json earlier and somehow that doesn't seem to work for me. I read that KVMODE is only for search-time extractions and not index-time. Do you have any suggestions for this?

Another weird thing that I am noticing is that, it works fine when I analyze the logs when uploading it and using the same sourcetype, but it appears to not work after I upload it and start the search. This is not the 1st time I am seeing this, it happened to me once before. Is the log analyzer in splunk 6.2 not working properly?

I just tested the same sourcetype with splunk 6.1 and it works perfectly! Safe to assume that something is wrong with Splunk 6.2 indexing
