This document discusses Nagios notification plugins and best practices for programming notifications. It describes various notification methods that can be used both at the office and on the go, such as email, phone, SMS, RSS, instant messaging, and support queues. When programming notifications, it is important to separate content generation from transport, handle timeouts properly without getting killed, think in parallel using locks or Nan, and use standardized macros and environment variables to pass information to the notification script. Notifications should have only one chance to succeed and return value is not used, but returning 0 indicates success.

- 43. Programming Notifications • Separate content generation from the transport – Think UNIX style – generate_content | transport_the_message • echo “$MACRO$ on $MACRO$” | sendmail • You only have one chance, so do it right – Nagios will “timeout” your notification script (be prepared) • If you should not be killed, detach the process • Think in parallel (serialize with locks or look at Nan) • You cannot return failure (or success)
- 44. Programming Notifications • Language neutral • Info about the notification – Command Line options (macros) vs Env Variables • http://nagios.sourceforge.net/docs/2_0/macros.html • http://nagios.sourceforge.net/docs/3_0/macrolist.html • Return value – Not used (but try to return a 0 if all goes well)
