I'll have a look, but no firewall configuration changes - or activity I can correlate to the alerts.

Checking logs to see if anything untoward is happening, is a good idea though.

That's correct.

I got an absolute ton of email only alerts and a few sms's last night, nothing was down.

Now it's failed and gone to critical and eventually sent an SMS instead of an email for that host. Host is fine and completely accessible. connect to address REDACTED and port 443: Connection refused Does it matter I'm using host_name instead of host_address in host blocks? I don't want this to turn...

I might just remove the check for that host ... ha
