The most of us are getting bored by receiving hundreds of monitoring emails every day. To master the flood, rules are getting in play - and with that rules the interest into email communication are reduced.
To master the internal information flood, business messaging networks like Slack are taking more and more place.
To make CM work with Slack a custom alert script from my Github will do the trick:
The use is pretty straight forward - create a channel in Slack, enable Webhooks, place the token into the script, store the script on your Cloudera Manager host, make it executable for cloudera-scm : and enable outgoing firewall / proxy rules to let the script chat with Slack's API. The script can handle proxy connections, too.
In Cloudera Manager, the script path needs to be added into Cloudera-Management-Service => Configuration => Alert Publisher => Custom Script.
