I created a trigger for a flume in cloudera manager, with a certain condition (Eps drops to < 5). Here is the condition:
SELECT event_put_success_rate_across_flume_channels WHERE entityName="flume" AND last(event_put_success_rate_across_flume_channels) <= 5.
It is triggering now as seen in the CM UI. However I was expecting it to also send alert by email, which it does not. I am getting alerts by email on other things but not the custom triggers. What am I missing in configuring my trigger/alert?
I restarted Flume, Alert Publisher and the CM service management as well. Anything else I am missing?

Ok, this is resolved. The problem was the alert threshold was set to send emails when a service enters a Bad state. However the trigger expression was "DO health:concerning"
Once I changed it to "DO health:bad" it worked. User mistake, again :(
