TASK DESCRIPTION This is a followup in the context of migrating wikidata alerts to AlertManager (T287741 <https://phabricator.wikimedia.org/T287741>). The remaining Icinga checks are mostly about wikidata lag, namely fetching `https://www.wikidata.org//w/api.php?action=query&meta=siteinfo&format=json&siprop=statistics` to compare the lag value to a threshold (in a shell script) The `siteinfo` statistics are of general interest and I think it makes sense to have them in Prometheus. In practical terms we'd teach production Prometheus to fetch the siteinfo api call like any other endpoint. A practical but fictional example of what I mean is the following: $ curl -s 'https://www.wikidata.org/w/api.php?action=query&meta=siteinfo&format=PROMETHEUS&siprop=statistics' mediawiki_api_dispatch_median_lag_seconds: 1 mediawiki_api_dispatch_freshest_lag_seconds: 1 mediawiki_api_dispatch_stalest_lag_seconds: 1 ... The exact metric names and labels are TBD but that's the general idea. This isn't full Prometheus support (in place of statsd, see T240685 <https://phabricator.wikimedia.org/T240685>) but IMHO going in the right direction, also in the context of T249164 <https://phabricator.wikimedia.org/T249164>. What do you think?
