... because it bothered me that it wasn't also add in a few more relevant aspects to our current approach to development, to keep this in line with how the project actually works. Change-Id: I6aa66263b3018d07512083cad86945295457ded1

"Classify tempest-devstack failures using ElasticSearch"
- Free software: Apache license
- Documentation: http://docs.openstack.org/developer/elastic-recheck
Idea
When a tempest job failure is detected, by monitoring gerrit (using gerritlib), a collection of logstash queries will be run on the failed job to detect what the bug was.
Eventually this can be tied into the rechecker tool and launchpad
queries/
All queries are stored in separate yaml files in a queries directory
at the top of the elastic_recheck code base. The format of these files
is ######.yaml (where ###### is the bug number), the yaml should have a
query keyword which is the query text for elastic
search.
Guidelines for good queries
- After a bug is resolved and has no more hits in elasticsearch, we should flag it with a resolved_at keyword. This will let us keep some memory of past bugs, and see if they come back. (Note: this is a forward looking statement, sorting out resolved_at will come in the future)
- Queries should get as close as possible to fingerprinting the root cause
- Queries should not return any hits for successful jobs, this is a sign the query isn't specific enough
In order to support rapidly added queries, it's considered socially acceptable to +A changes that only add 1 new bug query, and to even self approve those changes by core reviewers.
Future Work
- Move config files into a separate directory
- Make unit tests robust
- Add debug mode flag
- Expand gating testing
- Cleanup and document code better
- Sort out resolved_at stamping to remove active bugs
- Move away from polling ElasticSearch to discover if its ready or not
- Add nightly job to propose a patch to remove bug queries that return no hits -- Bug hasn't been seen in 2 weeks and must be closed
- implement resolved_at in loader
