Hi,
I have a working SMSTools and Nagios. Nagios is currently only monitoring services such as HTTP, SSH and FTP.

1) I am currently using postpaid and at times have forgotten to pay my bills and as such, no SMS can be sent out. Would it be possible to configure Nagios to monitor such events ? Any examples ?

2) How would one normally monitor SMSTools with Nagios. I mean, how would you monitor whether SMSTools is running is the first place ? Does it make use of any port that Nagios can monitor ?


TIA.

You could monitor the failed directory, and check if there are new messages. In the message file there is a Fail_reason header, which tells what was the response from the SMSC. In the case of unpaid bills it is something like "+CMS ERROR: 302 (Operation not allowed)".

SMSTools does not use any port.

Some external scripts can be used for detecting if SMSTools is running. For example, see this post.
