Issue Details

• I want to monitor the CPU and memory usage of a network-connected Real-Time (RT) controller using NI Distributed System Manager (DSM). I selected the RT target of interest from the tree in the left-hand window and then made sure to enable Auto View by selecting View»Auto View. I expected to see the CPU/Memory tab, but it did not show up. How can I view the CPU and memory usage of my real-time controller?
• When selecting my RT controller on DSM, the CPU/Memory, VI States, and Alerts tabs are missing. 

How can I fix this?

Solution

This information (CPU/Memory, VI States and Alerts) is provided by the System State Publisher software. This package must be installed in your controller to display the information in the Distributed System Manager. If this package is already installed and you can't still see these tabs, see the Additional Information section.

To install the System State Publisher package in your RT controller, follow these steps:
1. Open NI Measurement & Automation Explorer (NI MAX). You can do this by selecting Start»Programs»National Instruments»NI MAX.
2. Expand Remote Systems in the Configuration window.
3. Select your remote system (RT target) from the configuration tree. Right-click Software and select Add/Remove Software.
4. Once the installation window is opened, go to the Add tab, select System State Publisher, and press Review changes. Then, click Continue as seen in the image below.

5. Once the controller reboots, access the NI Distributed System Manager by navigating to Start»Programs»National Instruments»NI Distributed System Manager. Add your controller by right-clicking the My Systems folder and selecting Add System. Type in your controller's IP address in the pop-up window. 
 6. Once your controller has been added, you will be able to see the missing tabs in the Distributed System Manager software.
 

Additional Information

• This issue may also occur if the real-time target has inconsistent IP settings . Please check NI MAX to see if this issue is occurring and if so, use the linked article to ramify that error.
• This issue might also occur in some targets if the Embedded UI is enabled on them. This is a known issue, and the current workaround is to disable the Embedded UI.
• There is a known issue when installing the NI-Industrial Communications for CANopen package. This happens when installing both packages at the same time or the NI-Industrial Communications for CANopen after the System State Publisher. To fix this issue, first install the NI-Industrial Communications for CANopen and then the System State Publisher package. If your system is already in a bad state (the tabs are missing), you can follow one of the following options:
  1. Format the target (right-click the target on NI MAX and select Format Disk) and reinstall the software.
  2. Remove all software using the Remove Tab. Then, reinstall the required software in the right order.
