Indexes.conf setting for 90 days retention?

[abhi04]

Hi All,

I have total of 30 GB of total data to be indexed which after indexing will be 15 GB as per splunk average compressing.

I have a total of 4 indexers with 1 TB of disk space. Can you please let me know the indexes.conf setting on each indexer for a retention of 90 days of searchable data in splunk. Does the below settings work or there can be some improvements that can be made?

I got this from the splunk sizing app.

indexes.conf

# volume definitions

[volume:hotwarm_cold]

path = /mnt/fast_disk

maxVolumeDataSizeMB = 996148

# index definition (calculation is based on a single index)

[index_name]
homePath = volume:hotwarm_cold/defaultdb/db
coldPath = volume:hotwarm_cold/defaultdb/colddb
thawedPath = $SPLUNK_DB/defaultdb/thaweddb
homePath.maxDataSizeMB = 53760
coldPath.maxDataSizeMB = 345600
maxWarmDBCount = 4294967295
frozenTimePeriodInSecs = 8985600
maxDataSize = auto

This should be fine.

@richgalloway , any suggestions regarding the maxHotBuckets and  maxWarmDBCount. Any best practise rearding those? What if I remove these two parameters and the config file looks like below. Will this be better or the previous settings?

homePath = volume:hotwarm_cold/defaultdb/db
coldPath = volume:hotwarm_cold/defaultdb/colddb
thawedPath = $SPLUNK_DB/defaultdb/thaweddb
homePath.maxDataSizeMB = 53760
coldPath.maxDataSizeMB = 345600
frozenTimePeriodInSecs = 8985600
maxDataSize = auto_high_volume
