Nagios – Send alerts to twitter

Posted by Buzz in Nagios, twitter

Pre-req reading:

Nagios customization: Alerting via SMS, or anything you like!

Making the bird tweet using python

or
Update twitter in a single line

This entry will cover how to send nagios alerts to twitter, in the examples to follow curl will be used however you can choose to use the python example (link above) in place of this.

Firstly edit /usr/local/nagios/etc/objects/commands.cfg

And add the two following commands.

UPDATE 24/03/2011 Twitter no longer supports basic auth, use my oAuth updater here

define command {
        command_name    notify-by-twitter
        command_line    /usr/bin/curl --basic --user "twitteruser:twitterpassword" --data-ascii "status=[Nagios] $NOTIFICATIONTYPE$ $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$" http://twitter.com/statuses/update.json
}

define command {
        command_name    host-notify-by-twitter
        command_line    /usr/bin/curl --basic --user "twitteruser:twitterpassword" --data-ascii "status=[Nagios] $HOSTSTATE$ alert for $HOSTNAME$" http://twitter.com/statuses/update.json
}

Now define a contact for this twitter service

/usr/local/nagios/etc/objects/contacts.cfg

define contact{
        contact_name                    twitter
        service_notification_commands   notify-by-twitter
        host_notification_commands      host-notify-by-twitter
        service_notification_period 24x7
        host_notification_period 24x7
        service_notification_options a
        host_notification_options a
}

Choose your own notification options, for my feed I only choose alerts, I also have this send updated to a ‘private feed’ which I then follow.

Add this contact into your existing contact groups, i.e.

define contactgroup{
        contactgroup_name       admins
        alias                   Nagios Administrators
        members                 nagiosadmin,sms_alert,twitter
        }

Then run a nagios-verify to ensure you have no syntax errors, and restart nagios.

Trigger an alert by manually switching a monitored service off or entering a manual result to test.

Subversion and twitter – Keep your followers up to date with your code commits

Posted by Buzz in python, twitter

Some two months after the fact, I thought it may well be time to post a blog on this little code snippet.

As some of you have noticed every commit message to my subversion repository is infact updating my twitter.

This code was uploaded to subversion on 10/06/2009, so sorry for the late write up!

Requirements

Python 2.5 or higher
Subversion server

Installation

  • svn co http://svn.saiweb.co.uk/branches/python/svn_tweeter.py /usr/bin/svn_tweeter
  • chmod +x /usr/bin/svn_tweeter
  • cd /path/to/svn/hooks
  • Edit post-commit with your favorite text editor
1
2
REPOS="$1"
REV="$2"
1
 
1
/usr/bin/python /usr/bin/svn_tweeter -u twitterusername -p twitterpassword -r $REV -s $REPOS

Now try a commit, and check your syslog for entries from the script.

Aug 24 11:36:26 132 python: SVN_TWEETER: http://twitter.com/statuses/update.json query complete

UPDATE 24/03/2011 Twitter has removed basic authentication, you must use oauth (admittedly it has been like this for a fair while now) use this nagios_bot instead
