Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Applicability

Splunk Enterprise Splunk Cloud

Description

A user challenges the accuracy of the reported license usage.

Using the var/log/splunk/license_usage.log* to calculate the daily license usage and the result is much smaller than the one reported by License Master.

Investigation

It was found that the records in the license_usage.log.* files roll very fast and the 6 files (license_usage.log, .log.1, ...., .log.5) only cover about 2 hours' license usage.  These cannot be used to accurately calculate the daily license usage.

Resolution

You should use license_usage_summary.log* to calculate the daily license usage.  The following is the SPL search. 
index=_internal type=RolloverSummary host=* source=*license_usage.log* stack=*
| eval
    volumeb_gb = round(b/1024/1024/1024,3),
    stack_gb = round(stacksz/1024/1024/1024,3)
| fields - no_field
| timechart span=1d
    sum(volumeb_gb) as "Volume",
    values(stack_gb) as "Stack Size"
| reverse
