With this config i assume i should be getting email notifications only after N number of occurrences have occurred. But that doesn't seem to happen.

{
  "checks": {
    "cron_check": {
      "command": "/etc/sensu/plugins/check-procs.rb -p crond -C 1 ",
      "interval": 10,
      "standalone": true,
      "aggregate":true,
      "handlers": [ "mail" ],
      "occurrences": 10,
      "refresh": 30
    }
  }
}
