Nagios XI expands upon the capabilities of the Nagios Core software to provide you with detailed host and service monitoring for your critical IT systems.
The guide below describes how to integrate your Nagios XI installation with PagerDuty using our easy to install agent. Note that you must be logged in as
root to complete the installation. Please contact our support team if you have any trouble completing the integration.
Note: If you are running Nagios on CentOS 5, you will need to use the Perl-based integration for Nagios XI instead of following this guide.

command_filevariable points to your Nagios command file. The path can be found by running the command
grep "^command_file" nagios.cfgin the directory where

command_filevariable is uncommented (doesn’t start with a
pagerduty.cgito the Nagios Core cgi-bin (not the Nagios XI PHP user interface directory).For the virtual machine image provided by Nagios Enterprises this is
mv pagerduty.cgi /usr/local/nagios/sbin
pagerduty.cgiexecutable.For the virtual machine image provided by Nagios Enterprises:
chmod +x /usr/local/nagios/sbin/pagerduty.cgi
yum install perl-CGI perl-JSON perl-libwww-perl
Note: Unless you’ve disabled it, the Nagios Core web interface requires a username and password. We highly recommend configuring a user that is able to run Nagios commands that is only used for the webhook.
If you go to this URL in your browser you should see
400 Requests must be POSTs. If you do not see this, check your web server logs for details on what happened when you tried to call this URL.
The two-way integration requires that your Nagios server be accessible over the internet to receive webhook calls from PagerDuty. If you wish to restrict access to your Nagios web server to specific IPs, you can find PagerDuty’s webhook IPs in our knowledge base: What are PagerDuty’s IPs for whitelisting and firewall purposes?
Alternatively, services like ngrok can be used to create a secure tunnel to your Nagios server with a public URL that can be used for your webhook.
This is easy to do with the current integration, as a Nagios XI service in PagerDuty is directly mapped to a “contact” in Nagios. In order to configure multiple services, simply create additional contacts in Nagios XI with different names (i.e.
pagerduty_network, etc.), then copy and paste the corresponding Integration Key from PagerDuty into the
pager variable definition field, and make the contact part of a contact group which will receive notifications for your desired services. Don’t forget to apply your changes after saving your contact so they take effect.
If a PagerDuty server can’t be reached for any reason, events will be stored to an on-disk queue. The PagerDuty agent will attempt to re-send the events when connectivity is restored.
You should configure an external ping check service such as StatusCake or NodePing to monitor your site’s external connectivity. Of course, you can use PagerDuty to receive alerts from these services as well.
First, make sure you’ve installed the PagerDuty Agent, and that there were no errors from your package manager when attempting to install it. Failed installs (i.e. due to an incompatible distribution, such as CentOS 5) are the most common issue with the integration not working.
Check that the
pagerduty contact is getting the
SERVICE NOTIFICATIONS in syslog. You can grep your syslog to see if the
pagerduty contact is being notified. Here’s an example:
grep NOTIFICATION /var/log/messages May 28 18:20:57 ip-10-11-139-249 nagios3: SERVICE NOTIFICATION: pagerduty;localhost;Current Users;CRITICAL;notify-service-by-pagerduty;USERS CRITICAL - 3 users currently logged in
As you can see, the
pagerduty contact was notified for this
SERVICE NOTIFICATION. If the
pagerduty contact never shows up, that means that the
pagerduty contact is not associated with notifications for the host/service in question. If you’re using the default configuration, make sure that the
pagerduty contact is a member of the admins contact group. If the
pagerduty contact is getting notified, check the agent log at
More troubleshooting tips can be found in our Nagios Troubleshooting Guide.
PagerDuty can process
RECOVERY messages. All other messages, including
FLAPPINGSTOP, are ignored.
We have a guide for Customizing Notifications Sent to PagerDuty from Nagios to help you get started.
