Hey there Splunkers!
Similar to the question "How is the Size value on the job page calculated and logged in Splunk?" how can I determine how much disk is scanned when a search is run?
I can get the event_count
and scan_count
from the search head logs, but are bytes scanned logged in a file anywhere, or do I have to use diskUsage
in | rest splunk_server=local /services/search/jobs
?
Gracias!
Hi @Beaker77,
what do you mean with "scanned"?
if you mean disk used for each search job one Splunk server you can use diskUsage.

Hey @gcusello - By scanned I mean the total number of bytes examined in a search (not necessarily the number of bytes returned in the results).
The docs say diskUsage is "The total amount of disk space used, in bytes." so I think that's the compressed size of the matching events returned from a search as stored on disk in the dispatch folder.
Thanks for chiming in 🙂
Hi @Beaker77,
sincerely I don't know the total number of bytes examined and I don't know if it's possible to extract it.
It's possible to know the number of scanned events and you could calculate an average, but anyway why do you need to know this?
You can have the number of scanned events from Job Inspector or taking from job properties scan.count
.
For more details see at https://docs.splunk.com/Documentation/Splunk/8.0.0/Search/ViewsearchjobpropertieswiththeJobInspector .
Ciao.
