It appears that no events of the "apache2" type have been stored in logstash since 2014-01-31T23:59:59.000Z. These events are used to drive the fatalmonitor dashboard.
I tried restarting the logstash instance on logstash1001 but this did not seem to restore the event stream. Events of other types are being recorded which are delivered via the udp2log transport stream. fluorine.eqiad.wmnet is still adding new lines to /a/mw-log/apache2.log.
