Hi, Kindly help me out with to solve this question

When I try to parse the log event data into splunk which is in the multiline format, the timestamp is not identified correctly by splunk. It shows error that it "failed to parse timestamp". how to resolve this issue.

My log will be looking like this:

201907231345267473.00
10-24-00 aaaa bbbbb cccccc

here date is 2019-07-23 and time is 10-24-00
But these two line are identified as single event by enabling SHOULD_LINEMERGE = true

You can put this in datetime.xml in your app and deploy to first splunk enterprise instance in the input chain. I dont think its needed on the universal forwarder, but i forget if thats the truth or not.

<datetime>
  <define name="_custom_datestamp1" extract="year, month, day">
    <text><![CDATA[(?i\*\*)(\d{4})(\d{2})(\d{2})]]></text>
  </define>
  <define name="_custom_timestamp1" extract="hour, minute, second">
    <text><![CDATA[(?i)^(\d{2})-(\d{2})-(\d{2})]]></text>
  </define>
  <timePatterns>
    <use name="_custom_timestamp1"/>
  </timePatterns>
  <datePatterns>
    <use name="_custom_datestamp1"/>
  </datePatterns>
</datetime>

the changes will only apply to NEW data ingested after the datetime.xml is deployed.
