#3. Creating a ZenPack

When logged into Zenoss as an Administrator click on the Setting link and then on the ZenPacks tab. Select the "Create a ZenPack..." menu item. You will get a dialog asking for a name for your new ZenPack. The name must be of the form ZenPacks.<organization>.<identifier>, where organization is a name that identifies you or your organization and identifier is a string that represents the intent of your ZenPack. For example, ZenPacks.zenoss.HttpMonitor was created by Zenoss to help monitor HTTP sites. Once you have entered a name click the save button. This creates both the ZenPack object in the database as well as a new directory in the file system $ZENHOME/ZenPacks/<your zenpack id>.

Many types of objects can be added to a ZenPack via the user interface. Some examples are:

  • Device Classes

  • Event Classes

  • Event Mappings

  • User Commands

  • Event Commands

  • Service Classes

  • Device Organizers

  • Performance Templates

Devices are the conspicuous omission from this list. Any individual Device is usually specific to a particular site and therefore not likely to be useful to other Zenoss users.

To add one of these database objects to a ZenPack navigate to that object and use the "Add to ZenPack..." menu item. Zenoss will present a dialog which lists all installed ZenPacks. Select the ZenPack to which you want to add this object and click the Add button. To view the objects that are part of a ZenPack navigate to the Settings page then the ZenPacks tab. Click on the name of the ZenPack and you will see a page that lists both the files and the objects that are part of this ZenPack. You can remove objects from the ZenPack by selecting the checkboxes next to them and using the "Delete from ZenPack..." menu item.

ZenPacks can contain items that are not Zeo database items, such as new daemons, Data Source types, skins, etc. These are added to a ZenPack by placing them in the appropriate subdirectory within the ZenPack's directory. See the Core ZenPacks for examples of how to incorporate such items into your ZenPack. Further information regarding ZenPack development is available in the Zenoss Developer's Guide.

Discussion regarding development of ZenPacks takes place on the zenoss-dev mailing list and forums

#3.1. Packaging and Distributing Your ZenPack

To create the installable .egg file for a ZenPack use the "Export ZenPack..." menu item in the page menu when viewing a ZenPack. The dialog that follows has two options. The first option simply exports the ZenPack to a file named <ZenPackId>.egg in the $ZENHOME/exports directory on the Zenoss server. The second option does the same but then downloads the exported file to your browser. Other Zenoss administrators can install this exported .egg file as described in the Installing ZenPacks section.

For information on how to make your ZenPack available on the zenoss.com site see these instructions.
