Monitoring system resources

You can determine the processor usage, memory usage, and disk capacity on the host system from the Dashboard page.

Before you begin

The following minimum requirements must be met for the virtual machine. Depending on the size of your environment and your use of Configuration Patterns, additional resources might be required for optimal performance.
  • Two virtual microprocessors
  • 8 GB of memory
  • 192 GB of storage for use by the XClarity Administrator virtual appliance.
  • Display with a minimum resolution of 1024 pixels in width (XGA)
The following table lists the minimum recommended virtual-machine configurations for a given number of devices. Keep in mind that if you run the minimum configuration, you might experience longer than expected completion times for management tasks. For provisioning tasks such as operating system deployment, firmware updates, and server configuration, you might need to increase the VM resources temporarily.
Number of Managed Devices Virtual CPU/Memory Configuration
0 - 100 devices 2 vCPUs, 8 GB RAM
100 - 200 devices 4 vCPUs, 10 GB RAM
200 - 400 devices 6 vCPUs, 12 GB RAM
400 - 600 devices 8 vCPUs, 16 GB RAM
600 - 800 devices 10 vCPUs, 20 GB RAM
800 – 1,000 devices 12 vCPUs, 24 GB RAM
  • A single XClarity Administrator instance can support a maximum of 1,000 devices.

  • For the latest recommendations and additional performance considerations, see the XClarity Administrator: Performance Guide (White paper).

  • Depending on the size of your managed environment and the pattern of use in your installation, you might need to add resources to maintain acceptable performance. If you frequently see processor usage in the system resources dashboard displaying high or very high values, consider adding 1-2 virtual processor cores. If your memory usage persists above 80% at idle, consider adding 1-2 GB of RAM. If your system is responsive at a configuration as defined in the table, consider running the VM for a longer period to assess system performance.

  • For information about how to free up disk space by deleting XClarity Administrator resources that are no longer needed, see Managing disk space.


From the Lenovo XClarity Administrator menu bar, click Dashboard.

The host-system resource usage is listed in the XClarity Administrator Activity section.
The usage measurement indicates the number of XClarity Administrator processes that are simultaneously accessing the processors on the host.
Tip: The usage measure might occasionally spike to High or Very High. If the usage remains at these level for more than 30 minutes, check the jobs log to see if long running jobs are in progress (see Monitoring jobs).

The total-capacity measurement indicates the number of processors that are available on the host.

The usage measurement indicates the amount of memory that is currently in use by XClarity Administrator.

The total-capacity measurement indicates the total amount of available memory on the host.

User Data
The usage measurement indicates the amount of disk space that is currently in use by XClarity Administrator on the host system.

The total-capacity measurement indicates the total amount of space (used and unused) that is allocated for user data, such as operating systems and firmware updates.

For more information about managing disk space, see Managing disk space.

Attention: If the allocated resources are insufficient to handle the current number of managed devices with good performance, consider increasing the resource allocation. For information about recommended hardware requirements based on the number of managed devices in your environment, see Supported host systems.
