TASK DESCRIPTION As a user and a maintainer of WDQS, I want an expectation of service availability so that I know when issues can/should be resolved. The WDQS uptime SLO will be based on running a set of non-cached representative test queries periodically on the WDQS cluster, and comparing the time it takes for the queries to run against the baseline expectation; if this test time is over a TBD threshold, WDQS will be considered down, and require maintenance. This should approximate actual service availability for users. The tests will be non-cached and run against the entire cluster rather than per host. Example -- test queries are run hourly should not take more than 200% time to run over baseline (<200ms if baseline is 100ms). Goal is to keep this uptime 95% of the time. Sub-tasks: [ ] Create set of test queries (starting from Andrea's work) [ ] Establish baseline for test queries [ ] Establish SLO for test queries AC: - SLO for WDQS uptime is established - SLO for WDQS uptime is viewable on WDQS dashboard TASK DETAIL https://phabricator.wikimedia.org/T313751 WORKBOARD https://phabricator.wikimedia.org/project/board/891/ EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: RKemper, MPhamWMF Cc: MPhamWMF, Aklapper, AWesterinen, CBogen, Namenlos314, Gq86, Lucas_Werkmeister_WMDE, EBjune, merbst, Jonas, Xmlizer, jkroll, Wikidata-bugs, Jdouglas, aude, Tobias1984, Manybubbles
