About Compass Version 3

Compass™ is a modern mobile iOS and Android client for Horizon™ and Meridian™ OpenNMS® servers.

It provides a simple dashboard for viewing outage and alarm data, node details, graphs, and more.

New in Compass 3.2

3.2 is primarily a bugfix release, adding support for iPhone X, fixing a crash on Android 8 (Oreo) and higher, and fixing a few cosmetic bugs. Also, 3.2.1 adds support for adjusting the timeout used when connecting to OpenNMS, for slow network connections or servers.

New in Compass 3.1

3.1 is primarily a performance update, with improvements to a number of the underlying frameworks Compass uses.

It also includes a newer version of Backshift, our client-side graphing library, with a lot of great bug fixes and graphing improvements.

On iOS, 3.1 fixes iOS 11 support and adds the ability to auto-fill usernames and passwords with tools like LastPass and 1Password.

New in Compass 3.0

Since 2.x, Compass has had a huge internal update, a face lift, and probably a makeover or something. The codebase is leaner, faster, and has a number of new features, including:

  • Graphs! Compass 3.0 now supports resource graphs using the measurements API, available in Horizon 16 and above, and Meridian 2016.1.0 or higher.
  • Multiple server support! Now you can configure and switch between multiple OpenNMS servers.
  • Maps! (No, not those maps... *cough*) The node detail page will now show your node on a map if it has geolocation information.
  • Improved platform support. Some basic portions of Compass now work all the way back to OpenNMS 1.8, although we strongly recommend you upgrade, of course. :)

Also, Compass 3.0 does NOT have:

  • Ads! Thanks to everyone who supported Compass 2.0 but we decided to remove the ads to improve the experience for everyone.


Alarm Dashboard Outage Dasboard

Outage and Alarm Dashboard

At a glance, you can see a summary of any current outages and services with pending problems. One tap will take you to a more detailed view of outages or alarms.

On supported systems1, surveillance categories are also displayed, giving you quick access to availability just like your OpenNMS Horizon or Meridian server UI.

Alarm List Alarm Details

Alarm Details

You can view your current alarms, as well as acknowledge, escalate, and clear them — right from the list, or from the alarm's details.

Node Details

Node Details

View detailed information on your nodes, including SNMP attributes, address, availability information1, and outages.

If you are running the latest Horizon or Meridian release1, you can also view the geolocation of the node on a map, and update it with your current GPS location with the push of a button.

Dashboard Graphs Node Graphs


View and favorite node resource graphs and see them at a glance on the Compass dashboard2.

Frequently Asked Questions
