Bosun: only first notification being sent

问题


I am experiencing strange behaviour with my first-time Bosun config. It seems I'm receiving mail only first time the alert is being called. I am surely misunderstanding something.. Here's my .conf file:

smtpHost = ${env.BOSUN_MAIL_SERV}
smtpUsername =  ${env.BOSUN_MAIL_USER}
smtpPassword = ${env.BOSUN_MAIL_PASS}
emailFrom = ${env.BOSUN_MAIL_FROM}
httpListen = :8070
timeAndDate = 31
stateFile = ../bosun.state
ledisDir = ../ledis_data
checkFrequency = 10s
logstashElasticHosts = ${env.BOSUN_ES_HOSTS}

notification onError {
    email = elkarel@company.net
    print = true
}

template generic {
    subject = Test alert
    body = `<p>Alert: {{.Alert.Name}} triggered </p>`
}

alert company.errors.rate.exceeds0 {
    template = generic
    unknownIsNormal = true
    runEvery = 1
    $notes = "The rate of errors exceeds 1."
    crit = 1
    critNotification = onError
}

As you can see, crit is set always. However, nothing never happens. The Bosun output is like this:

So he knows the alert resulted in a critical state, but does not send any notification. However, if I change alert name to company.errors.rate.exceeds0_newname, the notification is fired and mail arrives:

Notifications are being sent apparently only with "new" alerts. Is this how Bosun works? Do I have to resend the notification until somebody acks it?

The mail server is gmail.

Thanks in advance!

Yes, Bosun only sends notification when an alert transitions from normal to warn or from warn to crit. You can, however chain notifications or even specify

notification onError {
    email = elkarel@company.net
    print = true
    timeout = 1m
    next = onError
}

That way Bosun will send notification every minute until the alert gets acknowledged.
