it seems like doesn't have any information.
Please assist for this issue.

I installed that app and loaded your data. It appears to parse just fine.
As far as I can tell, the empty fields are empty because they're not in the sample events.
The TA expects these fields in this order.
"id","date","time","description","ip","nt_host","mac","user","transaction_id","qresult","probation_time","correlation_id","dhcid","vendorclass_hex","vendor_ascii","userclass_hex","userclass_ascii","relay_agent","dns_reg_error"
If you're getting results like these then perhaps consider re-installing the TA.
Which app are you using (please share the splunkbase URL)? Is it installed on your indexers and heavy forwarders? Did you restart them after installation?
It seems like the data doesn't match the props supplied by the app. You may need to modify settings to match your data. Knowing the exact app will help us be more specific.
the app URL is as below:
Microsoft Windows DHCP addon for Splunk | Splunkbase
the app installed in search head and indexers, the data source is from UF. Already restart after the app installation.
Please advise, thank you.

Hi richgalloway,
Thank you for the reply. The actual event should be containing user's information but in splunk raw event we didn't receive much information.
i think we need to check the log from the DCHP server itself.
Thank you for your assist.
