Getting Data In

When does splunk roll data from warm to cold?

robertosegantin
Path Finder

On my test environement I configured and index like this:

[prove_di_cold]
homePath = /root/splunk_hot/prove_di_cold/db
coldPath = /root/splunk_cold/prove_di_cold/colddb
thawedPath = /root/splunk_cold/prove_di_cold/thaweddb
maxWarmDBCount=1
maxDataSize = 1000
maxHotSpanSecs = 40
frozenTimePeriodInSecs = 100
rotatePeriodInSecs = 60
bucketRebuildMemoryHint = 0
coldToFrozenDir = /root/splunk_frozen/prove_di_cold
compressRawdata = 1
enableDataIntegrityControl = 0
enableOnlineBucketRepair = 1
enableTsidxReduction = 0
minHotIdleSecsBeforeForceRoll = 0
rtRouterQueueSize =
rtRouterThreads =
suspendHotRollByDeleteQuery = 0
syncMeta = 1

But splunk never copy any data from hot/warm path to cold or freeze path

Have you got any other information about it?

Thanks

splunk wont roll the data until the bucket is full. its possible your hot bucket(s) arent full to even roll to warm even if the maxHotSpanSecs = 40 is set.

try setting this maxHotBuckets=x to a lower integer default is 3.

check with btool which settings are being applied.

./splunk btool indexes list --debug prove_di_cold

Hope I was able to help you. If so, some karma would be appreciated.

Weird because you have frozenTimePeriodInSecs = 100
