System Monitor

The System Monitor acts as your launchpad for services running on your Omniverse Nucleus. While running, it looks for installed Omniverse Services and launches them based on their configuration (currently only Snapshot Service is disabled from auto-launch).

Accessing the System Monitor

Right clicking on the icon brings up a menu where you can Access System Monitor or exit (quit) the Omniverse Nucleus services. The system monitor is comprised of 3 major tabs. Apps, Cache and Logs.



If Exited (Quit), the Omniverse Omniverse Nucleus will shut down along with associated services. It also will be removed from your system tray. To restart the system monitor, you will need to use the windows start menu to locate the Omniverse System Monitor found in the shortcuts installed with Omniverse. A Quick search for Omniverse Should reveal it.

Apps Tab

The Apps tab offers access to Omniverse Nucleus Services and allows you to check their status, start, stop and restart services as necessary.


Cache Tab

The Cache tab is found within the NVIDIA Omniverse™ Nucleus System Monitor under the Cache Tab and offers the ability to set your local cache directory, clear data accumulated by the cache service, and allows you to connect to an Upstream Cache Server.

System Monitor



Local Cache Directory

Local hard drive location where cache data will be stored.

Max Cache Size

Total data stored by Cache.

Cleanup Threshold

The limit at which cache clearing will stop, leaving recent files.

Disk Space Used

Displays used/available disk space on selected cache directory.


Clears the locally stored files in the Cache.


You can enable and disable local and remote by selecting the toggle in the top right of the respective pane.

Installing Cache on Secondary Computers

Any machine with the full Omniverse workstation installed will by default have omniverse cache. Alternatively the workstation installer can be configured to only install Omniverse Nucleus which includes the cache service. Each cache can be configured to use an upstream cache by entering the address into the Proxy Cache Server.

Servers Tab


Omniverse allows users to connect to multiple Omniverse Servers at a time. Though these connections can be made through tools like Omniverse Kit, Omniverse USD Presenter, Omniverse Maya Plugin etc. This tab allows you to maintain these connections in one localized place and reduces the need to log-in to servers on a tool by tool basis.

Adding Servers


To add a server, simply click on the “Add Server” button and enter the address of your server. If connecting to your own localhost server, you can use “localhost”.


Enter your credentials to continue or click “register” to create an account.


For organizations with NVIDIA SSO, you can use your single sign on credentials by clicking the SSO login and entering your credentials.


Once a server is set up, you will see it in the list of servers. You can continue to add Omniverse Nucleus servers and they will be listed here.


Removing servers can be done by clicking the 3 bars or the right top of a server and click remove.

Logs Tab

Cache Access and Status can be reviewed in the Logs Tab




If you are experience issues with your nucleus localhost, the first thing to check is that your system monitor is running. Please look in your windows system tray and check that the omniverse system monitor is running. It may be hidden so use the chevron to locate.
