LeanReoxHi guys, long time no see, can i bother you with a tresh question craigbr ddieterly  ?19:20
craigbrLeanReox: In a meeting for 40 minutes, yet19:21
LeanReoxno worries, i can wait craigbr , its about alarms not getting triggered19:22

craigbr@LeanReox: I'm back. What is your question?20:03
LeanReoxcraigbr, i have a healthy running environment, but when i set an alarm to test alarm trigger for example an easy on, cpu.idle_perc > 020:04
LeanReoxi dont get any alarm20:04
LeanReoxi see the topology on the storm cluster, metrics are persisted to influx ok20:04
LeanReoxso i need to know what to watch20:05
craigbrAre you getting any messages /var/log/storm/worker_*.log?20:05
LeanReoxcraigbr, lets check20:05
*** theresa_ has quit IRC20:09
*** ericpete_ has quit IRC20:14
LeanReox craigbr just reconnection to the zookeepers20:15
craigbrHow about in /var/log/storm/supervisor.log? It should be older than the worker-*.log files. If it is newer, then the workers aren't really running20:17
LeanReoxsome old communication errors with StatsD UPD client20:17
*** ericpeterson has joined #openstack-monasca20:17
LeanReoxlet me check craigbr20:17
LeanReox:q!20:17
LeanReoxok, here i have an iteresting error, java.lang.RuntimeException: java.io.EOFException20:18
LeanReox2015-04-06 20:17:55 b.s.event [ERROR] Error when processing event20:19
craigbrIs that event constantly occurring?20:22
LeanReoxlet me check20:23
LeanReoxno its from 3 days ago20:25
craigbrLet's see if it is consuming from kafka ok. Try:20:26
craigbr /opt/kafka/bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --topic events -zkconnect localhost:2181 --group thresh-event20:26
craigbrThat is assuming that zookeeper is on localhost and you haven't changed the default group in /etc/monasca/thresh-config.yml20:27
LeanReoxsorry my bad with the last question, the error is constantly ocurring20:27
LeanReoxim tailing the log and its constantly poping20:27
LeanReoxon the supervisor.log20:28
craigbrGood. That is pretty simple. Determine your storm.local.dir by looking in your storm.yaml. Our default is in /opt/storm/current/conf/storm.yaml20:28
craigbrsudo service monasca-thresh stop20:28
craigbrsudo stop storm-supervisor20:29
LeanReox/opt/storm/apache-storm-0.9.2-incubating/conf/storm.yaml20:29
LeanReoxsorry bad paste20:29
craigbrStop supervisor on all your nodes running thresh20:29
LeanReoxstorm local dir is set to /var/storm20:30
craigbrsudo stop storm-nimbus20:30
craigbrOnce you get all supervisors and nimbus stopped, then on all the nodes do:20:30
craigbrsudo rm -fr /var/storm/*/*20:30
craigbrThere is bad data and it can't read it so it keeps crashing20:30
LeanReoxok ... stopping thresh , killed topology20:30
craigbrThen restart nimbus20:30
craigbrThen restart all supervisors20:31
craigbrThen restart monasca-thresh20:31
craigbrDepending on how long it has been down, it may take a while to read all the queued metrics20:31
