Below is a working mailer handler configuration for Sensu. The mailer settings go to “/etc/sensu/conf.d/mailer.json” and then update the handler file “/etc/sensu/conf.d/handlers.json”.
shanker@mon1:~$ cat /etc/sensu/conf.d/mailer.json
{
"mailer": {
"type": "pipe",
"command": "handler-mailer.rb",
"admin_gui": "https://XXX/",
"mail_from": “alerts@XXXX",
"mail_to": [
“alerts@XXX" ],
"subscriptions": {
“group:XXXX_oncall": {
"mail_to": “sde@XXX"
},
"admins": {
"mail_to": “shanker.balan@XXXX"
}
},
"smtp_address": "localhost",
"smtp_port": "25",
"smtp_domain": “XXX"
}
}
shanker@mon1:~$ cat /etc/sensu/conf.d/handlers.json
{
"handlers": {
"default": {
"type": "set",
"handlers": [
"logstash",
"debug"
]
},
"mailer": {
"type": "pipe",
"command": "handler-mailer.rb",
"filters": [
"filter_warn_hourly"
],
"severities": [
"ok",
"warning",
"critical",
"unknown"
]
},
"sms": {
"type": "pipe",
"command": "handler-sms.rb",
"severities": [
"critical"
]
},
"logstash": {
"type": "pipe",
"command": "handler-logstash.rb",
"severities": [
"ok",
"warning",
"unknown",
"critical"
]
}
}
}
You can test by creating a dummy event and firing the handler manually.
Sample “event.json”
