Observation:
When nginx is stopped on client1 [subscription monitoring-sensupoc-sim] => I get emails sent to both name1@xyz. com and name2@xyz. com
Exact log:
{“timestamp”:“2019-05-13T22:21:44.228660+0000”,“level”:“info”,“message”:“handler output”,“handler”:{“type”:“pipe”,“command”:"/opt/sensu/embedded/bin/handler-mailer.rb -j mailerjson",“handle_flapping”:true,“severities”:[“warning”,“critical”],“filters”:[“occurrences”],“name”:“mailer”},“event”:{“id”:“d1708157-a14d-4b28-93ef-4a4cce5bb399”},“output”:[“mail – sent alert for client1/Nginx to , name1@xyz. com,name2@xyz. com\n”]}
Expectation:
All alerts from monitoring-sensupoc-sim should go only to name1@xyz. com. As stated on github.com sensu-plugins/sensu-plugins-mailer
There is an optional subscriptions hash which can be added to your mailer.json file. This subscriptions hash allows you to define individual mail_to addresses for a given subscription. When the mailer handler runs it will check the clients subscriptions and build a mail_to string with the default mailer.mail_to address as well as any subscriptions the client subscribes to where a mail_to address is found. There can be N number of hashes inside of subscriptions but the key for a given hash inside of subscriptions must match a subscription name.
