Field Extraction

[visa87]

Hi,

I am trying to read some systemout log files and extract data from it.
Sample info in the log is as below :

Field1 Accept Indicator :: true
Field1 Accept Indicator :: false
Field2 Accept Indicator :: true
Field2 Accept Indicator :: false
Total Time Taken by ReqA****156
etc

I am new to Splunk and not sure what is the correct approach to get these fields extracted..
I tried using the regex generated by Field Extraction but it does not give accurate results.

Can anyone help me with the regex as well?

For understanding the difference between having your extractions in props.conf vs transforms.conf, reading through the spec file for props.conf can be quite englightening:

http://docs.splunk.com/Documentation/Splunk/6.2.1/admin/Propsconf

Defining new search-time field extractions. You can define basic search-time field
extractions entirely through props.conf. But a transforms.conf component is required if
you need to create search-time field extractions that involve one or more of the following:
* Reuse of the same field-extracting regular expression across multiple sources,
source types, or hosts.
* Application of more than one regex to the same source, source type, or host.
* Delimiter-based field extractions (they involve field-value pairs that are
separated by commas, colons, semicolons, bars, or something similar).
* Extraction of multiple values for the same field (multivalued field extraction).
* Extraction of fields with names that begin with numbers or underscores.

Thanks... That helped. But I dont understand what can be achieved by adding these regex to transforms.

Then you can accept the answer which helped you.

You can do regex as follows:

.. | rex field=_raw "Field1.*\:\:\s(?<f1_value>\w+)"

That would get this for Field1, you can modify for each field, assuming this is a single line event.

For the total time event-

.. | rex field=_raw "ReqA(?<time_value>\d+)"

Again, these are for single line events. You can drop those regex's into props.conf or transforms for your sourcetime and extract them there.

I want to extract the time taken as a field and the numeric value as the value for tat field. Similarly I want Field 1 Accept Indicator as a field F1 which can either have true or false as value

First off, let us know what fields you want to extract, and what the values in your representative data looks like.. Then we can help!
