Getting Critical for HTTP:


HTTP

CRITICAL 04-03-2020 09:03:36 8d 4h 12m 32s 4/4 connect to address 66.248.241.245 and port 80: Connection refused

What is the full plugin command for this check?

It looks like either the server isn't listening on port 80 or something is blocking the connection for the Nagios server to the webserver.

Does a curl work from the Nagios server if you run:
?

[root@nagiosserver ~]# curl -v 66.248.241.245
* About to connect() to 66.248.241.245 port 80 (#0)

httpd service is inactive. We started httpd service.


But still we are getting Warning alert . Can you please check.

HTTP

WARNING 04-08-2020 08:23:36 0d 0h 0m 48s 4/4 HTTP WARNING: HTTP/1.1 403 Forbidden - 4299 bytes in 0.003 second response time

It looks like the server is responding with a '403 Forbidden' message. Do you want to see a CRITICAL instead of WARNING or are you expecting this request to be successful?

We have configured SMTP server with nagios server. We have to set the notifications alerts to one email for CPU alert only. Can you please tell us the steps.
