Nagios and twurl notifications


We’ve been using nagios for some time and have recently decided to change how we receive alerts. To this end, we’ve installed twurl ( ) and are using it to send alerts. Unfortunately this logs alerts as having been sent, but none get to the monitor’s twitter account. twurl uses a pretty standard CLI which looks like this (nagios macros left in tact):

Here’s the notification command:

define command { command_name notify-service-by-twurl command_line PATH="/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/nagios/bin"; HOME="/home/nagios"; /usr/local/bin/twurl -d "status=d @$CONTACTEMAIL$ $NOTIFICATIONTYPE$: $TIME$ : $HOSTALIAS$ / $SERVICEDESC$ is $SERVICESTATE$ ($SERVICEOUTPUT$)" /1/statuses/update.xml &>/tmp/lastcheck # command_line /bin/echo '/usr/local/bin/twurl -d "status=d @$CONTACTEMAIL$ $NOTIFICATIONTYPE$: $TIME$ : $HOSTALIAS$ / $SERVICEDESC$ is $SERVICESTATE$ ($SERVICEOUTPUT$)" /1/statuses/update.xml' > /tmp/foo }

Syntax works fine etc, no issues there. 1st line fires off the 2nd command_line line is to output the contents of the macros nagios uses, and returns what would be expected in all cases.

twurl pitfalls we’ve definitely avoided:

  • we’ve authed to twitter for nagios’s user (su’d in and checked, works fine when done manually).
  • the credentials of the app are correct (again, works fine when using twurl manually)
  • the settings of the twitter app ( on ) are correct (set to read/write direct messages etc)

I can provide any specific pieces of information anyone might need for extra context but for now that’s about it. Edit: I’m starting to suspect this is due to a lack of a .profile when nagios itself calls twurl, but I’m not 100% sure and still can’t make it “go”.


Try running your commands from a crontabbed shell script and outputting any returned errors to a text file…
