Search Log Processing
This app has been archived. Learn more about app archiving.
This app is NOT supported by Splunk. Please read about what that means for youhere.
Overview
For comparing indexer performance, understanding operators, or log levels (INFO .. CRIT), you have to leverage search.log. Indexing it isn't scalable though. This app will, every five minutes, launch a scripted input that will review the local dispatch directory for any search.log files, and the parse out the details into a JSON blob that will be put in index=_internal.
Details so far:
* Per Search Peer: # of Results
* Per Search Peer: Amount of time reported
* Time to set up search peers
* Count by log level of the search (e.g., INFO / WARN / ERROR / FATAL)
* Count by log operator of the search (e.g., “SearchOperator:kv” vs LMConfig)
* Time taken per operation (e.g., how many slow operations were there, how many fast ones — this can help identify particularly expensive regex / eval, etc.)
* SearchID
* Time Run
Overall, this should allow some trending information, and specifically to be able to detect an indexer that is slower than the rest.
