Using an SMS Server to Provide a Robust Alerting Service for Nagios
I’m a big fan of the Nagios network monitoring system and rely on it to tell me if something goes wrong with the systems for which I am responsible. I have made a large investment in time configuring Nagios to monitor exactly what I am interested in, and this effort would be wasted if Nagios detected a problem, but failed to communicate that problem to me. To make Nagios more robust, I wanted to make sure that its alerting mechanism did not depend on connections to the Internet—this would include the physical connection itself and internal and external services, such as e-mail, routing and DNS.
I have relied on e-mail-based systems in the past to deliver alerts; however, my dilemma was that if I was not getting e-mail, I did not know if this meant everything was okay or if there was some problem preventing me from getting the e-mail alerts, such as a down Internet connection or another kind of e-mail failure. I found that I became uneasy after long periods of silence and felt compelled to “poll” the system to make sure everything was okay.
On the other hand, I felt that if my alerting system was robust and I could trust it, my thinking would become “no news is good news”, and the absence of alerts would mean everything was fine.
