System dashboard

The first section of the Performance dashboard includes the System dashboard details. In the System dashboard section, you can view charts about current processor usage, current memory usage, current network traffic, and current storage traffic. The charts depict how the current processor usage, current memory usage, current network traffic, and current storage traffic of the system compare used capacity against the activated capacity. These charts represent if the overall server usage is consistently high, activate more processors, move workloads to other servers, or buy more servers, processors, or memory.

Current processor usage
The current processor usage graph shows the average processor usage and the peak processor usage for the selected system. The average processor usage is represented by a horizontal bar and the peak processor usage is represented by a vertical bar. This graph indicates the current and recent peak usage compared to the total activated processors on the server. Click the down arrow icon in the current processor usage area to view information about Installed, Activated, Allocated, Available, Used, Minimum, and Peak processor usage.
Current memory usage
The current memory usage graph shows the average memory usage and the peak memory usage for the selected system in GB. The average memory usage is represented by a horizontal bar and the peak memory usage is represented by a vertical bar. Click the down arrow icon in the current memory usage area to view information about Installed, Activated, Allocated, Available, Used, Minimum, and Peak memory usage. You can also view information about the Assigned virtual persistent memory. Persistent memory is available only when the Hardware Management Console (HMC) is at Version 9.1.940, or later, and when the firmware is at level FW940, or later. Persistent memory is a virtualization feature that creates persistent memory volumes by using the existing DRAM (Dynamic Random Access Memory). Here, data persistence is maintained across applications and the operating systems even when the logical partition is restarted.
Current network traffic
The current network traffic graph shows the average network traffic and the peak network traffic for the selected system. The network traffic is measured in bytes. The average network traffic is represented by a horizontal bar and the peak network traffic is represented by a vertical bar. Click the down arrow icon in the current network traffic area. The table shows information about:
  • Network traffic measured per second
  • Maximum amount of the network bandwidth used
  • Number of physical adapters
  • Number of reporting Virtual I/O Servers
  • Number of network bridges
  • Number of single root I/O virtualization (SR-IOV) adapters
Current storage traffic
The current storage traffic graph shows the average storage traffic and the peak storage traffic for the selected system. The average storage traffic is represented by a horizontal bar and the peak current storage traffic is represented by a vertical bar. Click the down arrow icon in the current storage traffic area. The table shows information about:
  • Storage traffic measured per second
  • Maximum amount of storage I/O bandwidth used by system
  • Number of VIOSs
  • Number of physical adapters
  • Number of NPIV adapters
  • Number of vSCSI adapters
