I am trying to decide on between zabbix and sensu for our environment. I
need some requirements

* an admin ui for configuration
* define different emails for different hosts for alerts
* run nagios scripts

I have a bunch of perl, sh and python scripts currently running under
Nagios environment. I thought migrating to sensu can be more easily but i
am not sure what are the prons and cons for Zabbix.

Anyone has an experience on it?

Is there any notification escalation on the free version of sensu?
