How to export/import selectively data from an indexer to another.
Here is the example for the defaultdb index (the main index)
with $SPLUNK_HOME = /opt/splunk
and a time period from April 10th 00:00 to April 11th 00:00 GMT (equivalent to 1302393600 to 1302480000 epoch time)
1 - roll the hot buckets to warm on the initial indexer
cd /opt/splunk/bin ./splunk _internal call /data/indexes/defaultdb/roll-hot-buckets -auth admin:changeme
2- identify the buckets containing data for your time period.
The dates are in epoch time UTC in the filename, in the reverse order.
the filename is db_recentevent_oldestevent_bucketuniquenumber.
You can use http://www.epochconverter.com/ to check
example : /opt/splunk/var/lib/splunk/defaultdb/db/db_1305913172_1301920239_29/ contains data for the period of to 1301920239 = GMT: Mon, 04 Apr 2011 12:30:39 GMT from 1305913172 = GMT: Fri, 20 May 2011 17:39:32 GMT
3 - export the events for the index and the period you need
usage : exporttool db_directory exportfile [-et <earliest_time_utc>] [-lt <latest_time_utc>] [-csv] [export_search] example : cd /opt/splunk/bin ./splunk cmd exporttool /opt/splunk/var/lib/splunk/defaultdb/db/db_1305913172_1301920239_29/ /myexportpath/export1.csv -et 1302393600 -lt 1302480000 -csv
4 - import each file into the new indexer, in the proper destination index
usage : importtool example : cd /opt/splunk/bin ./splunk cmd importtool /opt/splunk/var/lib/splunk/defaultdb/db /myexportpath/export1.csv "Successfully imported 71615 events into the bucket. Please ensure this bucket resides in a valid index and restart Splunk to recognize the new events."
example : ./splunk restart .... Perform recovery now? [y/n] y Recovering (across all data)... bucket=opt/splunk/var/lib/splunk/defaultdb/db/db_1306285067_1305920377_54 count mismatch tsidx=2525 source-metadata=2524, repairing... Done
A couple of corrections during import (at least with 4.2.5):
Can someone describe the syntax for this:
"If needed, you can also add a search as last parameter." ?
it looks like if I dd at the end 'some_string' it will filter based on that.
However if I do 'sourcetype=some_source' it returns nothing
Does this mean that I cannot use source type to search, or is my syntax incorrect?
