show cpu

This chapter includes the show cpu command output tables.


Important

The outputs of show cpu commands vary based on platform ASR 5000 or ASR 5500, VPC (virtualized), card type and the StarOS release.

show cpu info

Table 1. show cpu info Command Output Descriptions
Field Description

Card

Displays the slot number of the card.

CPU

Displays the CPU number as an integer.

Status

Indicates the CPU status:

Active: The CPU is active and available for session processing.Standby: The CPU is on standby.

Also indicates if Kernel Running and Tasks Running.

Load Average

Indicates the average CPU load.

Total Memory

Indicates the total physical memory available to the CPU in megabytes.

Kernel Uptime

Indicates how long the kernel has been up since last boot in Days, Hours and Minutes.

Last Reading:

Displays current CPU usage statistics (snapshot).

  CPU Usage

Indicates the percentage of use for user, system, I/O, IRQ and idle. In VPC systems, the value displayed excludes the poll CPU values.

  Poll CPUs

Indicates the number of the IFTASK threads. The IFTASK threads are ommitted from the CPU utilization calculation for this command output as well as the bulk statistics output. This means that the reported CPU utilization is more accurate.

  Processes / Tasks

Indicates the total number of running processes and tasks.

  Network

Indicates the number of packets and bytes received and transmitted.

  File Usage

Indicates the number of open and available files.

  Memory Usage

Indicates the amount of physical memory used in bytes and as a percentage of available memory.

Maximum/Minimum:

Displays maximum and minimum usage statistics.

  CPU Usage

Indicates the percentage of use for user, system, I/O, IRQ and idle.

  Poll CPUs

Indicates the number of the IFTASK threads. The IFTASK threads are ommitted from the CPU utilization calculation for this command output as well as the bulk statistics output. This means that the reported CPU utilization is more accurate.

  Processes / Tasks

Indicates the number of running processes and tasks.

  Network

Indicates the number of packets and bytes received and transmitted.

  File Usage

Indicates the number of open and available files.

Memory Usage

Indicates the amount of physical memory used in bytes and as a percentage of available memory.

Important 

In release 21.1, show cpu info outputs are standardized to use Megabytes (M) as the unit of measurement for memory usage.

show cpu info verbose

Table 2. show cpu info verbose Command Output Descriptions
Field Description

Card

Displays the slot number of the card.

CPU

Displays the CPU number as an integer.

Status

Indicates the CPU status:

Active: The CPU is active and available for session processing.Standby: The CPU is on standby.

Also indicates Kernel Running and Tasks Running.

Load Average

Indicates the average CPU load.

Total Memory

Indicates the total physical memory available to the CPU in megabytes.

Kernel Uptime

Indicates how long the kernel has been up since last boot in Days, Hours and Minutes.

Last Reading:

Displays current CPU usage statistics (snapshot).

  CPU Usage All

Indicates the percentage of use across all cores for user, system, I/O, IRQ and idle. In VPC systems, the value displayed excludes the poll CPU values.

    Core n

Indicates the percentage of use for an individual core within the CPU for user, system, I/O, IRQ and idle.

(VPC-DI only) Any Cores that are indicated as Poll CPUs are IFTASK threads that are not included in the CPU calculations.

    Poll CPUs

(VPC-DI only) Number of IFTASK threads that are not included in the CPU calculations. reported by this command.

    Core n

(VPC-DI only) Indicates the percentage of use for an individual Poll CPU core.

Note 

100% CPU utilization for DPDK is an expected behavior as the Poll Mode Driver (PMD) thread runs continuously on a core as per the DPDK driver architecture.

  Processes / Tasks

Indicates the total number of running processes and tasks.

  Network loeth0

Indicates the number of packets and bytes received and transmitted on the management interface.

  Network ports_p

Indicates the number of packets and bytes received and transmitted on a service interface (slot_port).

  File Usage

Indicates the number of open and available files.

  Memory Usage

Indicates the amount of physical memory used in bytes and as a percentage of available memory.

Memory Usage

Indicates the amount of physical memory used in bytes and as a percentage of available memory.

Important 

In release 21.1, show cpu info outputs are standardized to use Megabytes (M) as the unit of measurement for memory usage.

  Memory Details:

Displays more detailed memory usage statistics.

    Static

Indicates the amount of memory used by the kernel and system files in megabytes.

    System

Indicates the amount of memory used for temp storage, buffers and caches in megabytes.

    Process/Task

Indicates the amount of memory used for processes and tasks.

    Free

Indicates the amount of free (available) memory (including reserved).

    Usable

Indicates the amount of unreserved available memory.

  5-Minute Average

Displays the average CPU usage statistics for the last five minutes.

  15-Minute Average

Displays the average CPU usage statistics for the last 15 minutes.

show cpu table

Table 3. show cpu table Command Output Descriptions
Field Description

CPU

Displays the number of the CPU in the format slot_number /cpu_number .

State

Indicates the CPU state as one of the following:

Actve: The CPU is active and available for session processing.Sndby: The CPU is on standby.

Load

Indicates the CPU load for the following time intervals:

Now: Current load5min: Load within the last 5 minutes15min: Load within the last 15 minutes

CPU-Usage

Indicates the CPU usage as a percentage for the following time intervals:

Now: Current usage5min: Usage within the last 5 minutes15min: Usage within the last 15 minutes

Memory

Indicates the memory usage for the following time intervals:

Now: Current usage5min: Usage within the last 5 minutes15min: Usage within the last 15 minutes

In addition, the total memory available on the CPU is displayed.

The PSC has two CPUs, the main CPU (CPU 0) contains 16 GB of memory. The second CPU is contained within the card's NPU and provides an additional 512 MB of memory.The PSC2 has two CPUs, the main CPU (CPU 0) contains 32 GB of memory.
