show load

This command displays task level system usage.

Syntax

show load

Guidelines

The show load command displays the system usage by task. Use this command with the load-interval command to monitor system load.

The show load command displays memory usage for many tasks across the system, not for just the main task. The total memory usage from the show load command might be higher than the memory usage that displays with the show memory command. This discrepancy is because the show load command displays memory for these additional tasks.

The show load command displays the following status information.
  • The instance of the task.
  • The name of the task.
  • The percentage of total load for the tasks during the measurement interval. A load above 90 indicates that the task is at or near load capacity. High load values are not necessarily indicative of a problem, if transaction latencies are not affected. Low load values mean that the task is looking for work. High load values mean that the task is doing work.
  • The number of pending work items, including internal communication, in the queue for processing by the appliance. This number is for internal diagnostic tests and is not intended for capacity planning.
  • The percentage of processor capacity that is used by this task.
  • The percentage of memory that is used by this task. This ratio is relative to the amount of memory accessible to each task, rather than the memory accessible to the appliance as a whole. The cumulative task memory is not comparable to the memory usage as reported by the show memory command.
  • The number of open file handles. The file count increases when the appliance accepts new connections or opens a file for reading. The count decreases when this file handle is closed. The file count value helps to identify which tasks are contributing to the high open file counts.
