The splunk_instrumentation.log file is the least helpful in troubleshooting a crash, because it
contains information about the Splunk Instrumentation feature, which collects and sends usage data
to Splunk Inc. for product improvement purposes. This file does not contain any information about
the Splunk processes, errors, or crashes. The other options are more helpful in troubleshooting a
crash, because they contain relevant information about the Splunk daemon, the standard error
output, and the crash report12
