Hi!

Usually, the SMS messages are accomplished using an Email-To-Text-Address to send the notification. However, let's start with the email first. Is that working correctly?

You can send a custom notification via the web interface to test, check your spam folder if you don't receive it.

No alert received to my email. Is there any option, to get automatic alerts for warning and critical status.

Can you please post your updated configs showing the command definition for 'host-notify-by-email' and 'notify-host-by-sms'. If these don't exist then they will need to be created.

You haven't shown the command definitions themselves, they start with:

Code: Select all

Where did you come up with the notify-host-by-sms and host-notify-by-email commands? Did you invent them out of thin air or are you copying them from another example? I ask this because you don't have them defined at all and this is your problem.
