Return to Nagios


• 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)


• Language neutral• Info about the notification

– Command Line options (macros) vs EnvVariables

• 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)
