Zenoss 4 Integration Guide

Zenoss is a very popular open source network, server and application monitoring system used by thousands of IT organizations. It provides one of the best event management systems available in any open source monitoring system. The plug-in architecture of Zenoss allows it to be extensible by anyone.PagerDuty extends Zenoss’s functionality by providing on-call scheduling, alerts and incidents tracking through the PagerDuty API. You are notified of the most critical Zenoss events by PagerDuty so you are able to take immediate action.

This guide describes how to integrate your Zenoss 4 installation with the PagerDuty ZenPack. You might need to slightly alter these instructions depending on your exact Linux distribution and your Zenoss configuration. If you are having trouble completing the installation, please contact us.

In Zenoss 4:

  1. Login to your Zenoss server’s shell as root.  Open the /opt/zenoss/etc/zenactiond.conf file within your text editor.  Update the zopeurl parameter to the URL that you use to access your Zenoss web interface.  This parameter will be used to directly link from your PagerDuty console to your Zenoss web interface.  Note:  This can be an intranet URL.  Make sure to remove the # symbol from this parameter so that the field is activated.
  2. From your web browser, download the PagerDuty ZenPack to your local workstation.  Note:  Do not change the name of this file.
  3. From the Zenoss web interface, go to ADVANCED > Settings > ZenPacks > Click on the Gear Icon > Install ZenPack:install_zenpack
  4. Select the PagerDuty ZenPack that you downloaded and click OK.choose_egg

Post Installation

To verify that everything is working, you’ll want to trigger a new alert within Zenoss, which will in-turn trigger an incident within PagerDuty.  When viewing the details for an incident, you can use the View in Zenoss link to take you to the event within your Zenoss web interface.


Why did I receive this error “Failed to Install ZenPack ZenPacks.PagerDuty.APINotificiation-1.0.0-py2.71.egg. See event.log for details” when installing the ZenPack?

This is an issue with the version of Python that you have installed.  You can either install the ZenPack from source or change the filename from “ZenPacks.PagerDuty.APINotification-1.0.0-py2.71.egg” to  “ZenPacks.PagerDuty.APINotification-1.0.0.egg” and then reinstall the ZenPack.

How do I setup Zenoss to work with multiple PagerDuty services?

This is easy to do with the current integration, as each Zenoss notification can be associated with a PagerDuty service.  You would just need to add multiple notifications within Zenoss to tie to each of your PagerDuty services.

What if a Zenoss notification happens while my network is down?

If a PagerDuty server can’t be reached for any reason, Zenoss will re-send the notification to PagerDuty every 60 seconds.  This is configurable under the notification configuration.

Since Zenoss needs my external Internet connection to send failure reports to PagerDuty, how will I receive notification if our site loses external connectivity?

You should configure an external ping check service to monitor your site’s external connectivity. Of course, you can use PagerDuty to forward alerts from these services.

I unacknowledged an alert within Zenoss, but PagerDuty still shows it as acknowledged, what happened?

PagerDuty does not support unacknowledged incidents.  The event will remain as acknowledged within PagerDuty until it is resolved.

How can I customize the details of my alerts?

Other event properties can be found in Section 7.1.2 (Page 89) of the ZenOSS Core Administration Guide.  Note:  The Incident Key needs to be unique per incident.

How can I use a proxy to send notifications to PagerDuty?

You can do this by editing the ~zenoss/.bashrc file to include the http_proxy and https_proxy environment variables. The lines added would look like:

export http_proxy=http://my.proxyserver.com:3128/
export https_proxy=http://my.proxyserver.com:3128/

For the changes to take effect, you must either fully stop and start the Zenoss service or reboot the server.
