Splunk IT Service Intelligence

Set-up itsi_summary in indexes.conf to be on fast and also on slow disk

Hi All,

I have one question about ITSI indexes.
Our Splunk Indexer has 1 disk “fast” and 1 disk “slow” with more capacity (it is not that slow but performance are lower than the fast one). On the “fast” hot and warm buckets are present, instead on the “slow” cold buckets are there. This set-up is valid for all of our indexes, except for Splunk ITSI ones.

In fact currently Splunk ITSI has reached 30GB in our "fast" disk (with approximately more than 1 year of data) and I would like to set-up a limit of 20GB on “fast” disk volume:home and the rest on the “slow” one volume:cold.
We don’t usually inquiry data older than 1 month with ITSI.

I would like to change indexes.conf configuration as follow:

AS IS

[itsi_summary]
homePath   = volume:home/itsi_summary/db
coldPath   = volume:home/itsi_summary/colddb
thawedPath = $SPLUNK_DB/itsi_summary/thaweddb

TO BE

[itsi_summary]
homePath   = volume:home/itsi_summary/db
coldPath   = volume:cold/itsi_summary/colddb
thawedPath = $SPLUNK_DB/itsi_summary/thaweddb
#added to limit index size on fast disk
homePath.maxDataSizeMB = 20480

Do you see any contraindication on moving the coldPath from volume:home to volume:cold?

Thanks a lot,
Edoardo

Hot/warm and cold buckets can be in different volumes.

As per your use-case, 'coldPath' can be configured to slower disk.
