Total CPU Activity

This table displays the following CPU utilization information for a given LoadMaster:

Statistic

Description
User

The percentage of the CPU spent processing in user mode
System

The percentage of the CPU spent processing in system mode
Idle

The percentage of CPU which is idle
I/O Waiting

The percentage of the CPU spent waiting for I/O to complete

The sum of these four percentages equals 100%.

Core Temperatures: The temperature for each CPU core is displayed for LoadMaster hardware appliances. Temperature will not show on a Virtual LoadMaster statistics screen.

These values are only available using SNMP. For further information on SNMP Options, refer to the SNMP Options section.

CPU Details: To get statistics for an individual CPU, click the relevant number button in CPU Details.

The CPU details screen has two additional statistics displayed - HW Interrupts and SW Interrupts.

Memory usage

This bar graph shows the percentage (MB) amount of memory in use and the amount of memory free.

Network activity

These bar graphs show the current network throughput on each interface.

Note: For Elastic Network Adapter (ENA) driver interfaces, the speed displayed behaves similar to bonded interfaces in that the speed of the overall interface is the aggregate of the number of separate logical interfaces that have been defined on that interface.

Disk Usage

This section provides an indication of the percentage (GB) used/free of the log partitions. Color-coding is used to highlight different usage levels:

  • 0% to 50%: green
  • 50% to 90%: orange
  • 90% to 100%: red
