Troubleshooting- Why is the data only coming from 3 files?

[LogUx]

Hello Splunkers !!

I have 5 file paths which we are monitoring

D01A01023(Z+01) -- Data is not coming
D01A02023(Z+01) -- Data is coming fine
D01A03023(Z+01) -- Data is not coming
D01A04023(Z+01) -- Data is coming fine
D01A05023(Z+01) -- Data is coming fine

We have data similar files and logs patterns are same for all the files but even after that logs are coming to Splunk only from 3 files not all the files.

In that I have checked inputs.conf, props.conf & transforms.conf all are fine. But Still I am figuring out what more I need to check to troubleshoot this issue.

Check the output from

splunk list monitor

and

splunk list inputstatus

on the splunk component monitoring the files

Please share the inputs.conf stanzas for the 5 file paths.

@richgalloway To add crcSalt = <source> can resolve the issue ?

[richgalloway]

crcSalt=<SOURCE> can help prevent re-indexing of a file that has been renamed, but won't help with files that aren't indexed at all.

The regex in the whitelist doesn't match the file names in the OP.  For starters, none of the file names in with ".log".  This regex matches the example names, according to regex101.com

D[0-9]{2}A[0-9]{5}\(Z[+-][0-9]{2}\)

@richgalloway 

C:\\Firelog\D01A01023(Z+01).log 

That is the complete log path of one of the log

[richgalloway]

That fits the original regex (I'm assuming "Filelog" in the original is a typo).

Have you checked the logs to see if Splunk is reporting any errors accessing the files?

@richgalloway 

[monitor://c:\Filelog\*.log]
whitelist = [\/\\]D[0-9]{2}A[0-9]{5}\(Z(?:\+|\-)[0-9]{2}\).log$
disabled = false
index = abc
sourcetype = abc_logs
