Monitoring Splunk

How can we measure two removed monitored files?

A customer asked to remove two monitored files, which I did today.

They asked -

-- Is there a way we can get the exact difference in data per file to see exactly how much reduction this change will result in? Is there a way to combine the information in index=_internal and the |metadata logs?

Because this is a one-off, you can do something like this (with All time for Timepicker😞

index=foo sourcetype=bar
| eval bytes=len(_raw)
| stats sum(bytes) AS bytes BY source

You're looking for reduction of license usage OR event count? You get license usage by source, so you can look at previous usage for those files to see how much you've reduced.

It's interesting @somesoni2 as I refound your response at License usage for one index broken down by sourcetype

This is gorgeous @woodcock !!!

Quick question - our developer came up with the following query -

index=_internal sourcetype=splunkd source=*license_usage.log type=Usage idx=<index name> 
| stats sum(b) as usage by idx st 
| eval usage_MB=round(usage/1024/1024,3) 
| eventstats sum(usage_MB) as totalMB 
| eval perc=usage_MB/totalMB

Can we achieve these results without using the eventstats command?

This command is quicker and should give approximately the same result as my solution. If you do not care about breaking out by sourcetype, you can do something like this (without the eventstats😞

index=_internal sourcetype=splunkd source=*license_usage.log type=Usage idx=<index name> 
| stats sum(b) AS usage values(st) AS st BY idx
