How to resolve error "string index out of range" when anonymizing a diag?

When anonymizing a diag as per the following:

https://docs.splunk.com/Documentation/Splunk/6.5.0/Troubleshooting/AnonymizedatasamplestosendtoSuppo...

An error is encountered on certain log files:

Error reading file /Users/arowsell/Documents/xxtest/ananon_diag_test//test_fail_1_event_bad.log and getting terms: string index out of range

Steps to reproduce:

1) Run following command on attached file testfail1eventbad.log:

find pathtomyuncompresseddiag/ -name *.log* | xargs -I{} ./splunk anonymize file -source '{}'

2) Run the same command on the file testfail1eventgood.log and the error does not occur.

The only difference between the files seem to be the trailing white spaces at the end of the event.

The following bug was raised for this matter:

SPL-131827 : Error when anonymizing diag "string index out of range"

The error can be resolved by making the following changes

  • Open the file $SPLUNK_HOME/bin/scrubber.py
  • Look for MAXSEGMENT = 1024 - change it to MAXSEGMENT = 4096

Then re-run the anonymizing command
