Monitoring Splunk

component=HotBucketRoller caller=init_roll question

Good morning fellow Splunkers,

I am wondering what the caller=init_roll is and if someone could point me to some documentation about it, as I haven't found any yet.

Basically, I changed the maxDataSize in indexes.conf to 'auto_high_volume' (10GB) from the default of 750MB, and I assume I see all of the current hot buckets for that index rolling to warm so Splunk can start filling the new hot buckets that have the new, increased data size cap.

However, I haven't been able to find any documentation via google about the 'caller=init_roll' so I can confirm my educated guess.
