Displaying System Information

To display the system information for the ACE, perform the following task:

Command
Purpose

show system {cpuhog | error-id {hex_id | list} | internal | kcache | kmem | kmemtrack | resources | skbtrack | uptime | watchdog [lcp | memory | scp] }

Displays the system information.

The keywords and argument are as follows:

cpuhog—Displays information related to the process watchdog timer that monitors CPU usage by any currently active processes. This keyword is intended for use by trained Cisco personnel for troubleshooting purposes only.

error-id—Displays description about errors.

hex_id—Error ID in hexadecimal format. The range is from 0x0 to 0xffffffff.

list—Specifies all error IDs.

internal—Displays Cisco internal system-related functions. The internal keywords and related keywords, options, and arguments are intended for use by trained Cisco personnel for troubleshooting purposes only. This option is available in the Admin context only.

kcache—Displays the Linux kernel cache statistics..

kmem—Displays the Linux kernel memory usage.

kmemtrack—Displays the kernal memory allocations in the kernel loadable modules. This keyword is intended for use by trained Cisco personnel for troubleshooting purposes only.

resources—Displays system-related CPU and memory statistics.

skbtrack—Displays the socket buffer (network buffer) allocations in the kernel loadable modules. This keyword is intended for use by trained Cisco personnel for troubleshooting purposes only.

uptime—Displays how long the ACE has been up and running. This keyword is available in all user contexts.

watchdog [lcp | memory | scp]—Displays whether the watchdog is enabled or disabled. When the watchdog is enabled, its timeout is displayed. When you enter this keyword without an option, all watchdogs are displayed. To display a specific watchdog, enter one of the following options:

lcp—LCP process watchdog. The current SCP watchdog watches this process. However, if the LCP process is not scheduled on time, this watchdog reboots the ACE.

memory—Low memory watchdog when the ACE memory reaches 99 percent.

scp—Watchdog for SCP keepalive messages from the hardware timer interrupt level.

The system watchdog memory command allows you to configure the Memory watchdog timeout. The LCP and SCP timeouts are not configurable.

Table 5-10 describes the fields in the show system kmem command output.

Table 5-10 Field Descriptions for the show system kmem Command 

Field
Description

Mem

Total

Total usable Linux kernel RAM (physical RAM minus the reserved bits and the kernel binary code)

Used

Total Linux kernel RAM in use.

Free

Available Linux kernel RAM.

Shared

Always zero.

Buffers

Memory in buffer cache.

Cached

RAM used for the page cache (disk cache) minus the RAM used for the swap cache.

Swap

Total

Total amount of physical swap memory.

Used

Total swap memory in use.

Free

Available swap memory.

MemTotal

Total usable Linux kernel RAM (physical RAM minus the reserved bits and the kernel binary code).

MemFree

Available Linux kernel RAM.

MemShared

Always zero.

Buffers

Memory in buffer cache.

Cached

RAM used for the page cache (disk cache) minus the RAM used for the swap cache.

SwapCached

Memory that once was swapped out, is swapped back in, but is still in the swap file. If this memory is needed, it does not need to be swapped out again because it is already in the swap file. This saves I/O.

Active

Memory that has been used recently and usually not reclaimed unless it is absolutely necessary.

Inactive

Memory that is unused or easily freeable.

HighTotal

Total amount of memory in the high memory (highmem) region. Highmem is all memory above approximately 860 MB of physical RAM. The kernel uses indirect methods to access the high memory region. Data cache can go in this memory region.

HighFree

Total amount of available memory in the highmem area.

LowTotal

Amount of memory in the low memory region (non-highmem memory).

LowFree

Amount of free memory in the low memory region. The kernel can address low memory directly. All kernel data structures need to go into low memory.

SwapTotal

Total amount of physical swap memory.

SwapFree

Available swap memory.

Committed_AS

An estimate of how much RAM you would need to make a 99.99% guarantee that there never is an out-of-memory (OOM) condition for a particular workload. Normally, the kernel overcommits memory. For example, if you dynamically allocate 1 GB of memory, no demand is placed on that memory until you actually start using it. The Committed_AS is an estimate of how much RAM or swap memory you would need in a worst-case scenario.

Displaying or Collecting Technical Information for Reporting Problems

To display or collect general information about the ACE for use when reporting a problem, perform one of the following tasks:

Command
Purpose

show tech-support [details]

Displays general information about the ACE for use when you report a problem. You can use this command to collect a large amount of information about your ACE and provide the command output to technical support representatives.

This command displays the output of several show commands at once. The command output varies depending on your configuration.

The optional details keyword provides detailed information for each show command.

You can choose to have detailed information for each command or even specify the output for a particular interface or module. Each command output is separated by the line and the command that precedes the output.

The default output of the show tech-support command includes, for example, the output of the following commands:

show hardware—See the "Displaying Hardware Information" section

show interface—See the Cisco Application Control Engine Module Routing and Bridging Configuration Guide

show process—See the "Displaying General System Process Information" section

show running-config—See Chapter 4, Managing the ACE Software

show version—See the "Displaying Installed Software Information" section

When using this command, explicitly set the terminal length command to 0 (zero) to disable autoscrolling and enable manual scrolling. Use the show terminal command to view the configured terminal size. After obtaining the output of this command, reset your terminal length as required (see the "Configuring Terminal Display Attributes" section in Chapter 1, Setting Up the ACE).

You can save the output of this command to a file by appending > filename to the show tech-support command (see Chapter 4, Managing the ACE Software). If you save this file, verify that you have sufficient space to do so; each file may take about 1.8 MB.

   

tac-pac {disk0:[path/]filename | {ftp://server/path[/filename] | scp://[username@]server/path[/filename] | sftp://[username@]server/path[/filename] | tftp://server[:port]/path[/filename]}

Redirects the same information as the show tech-support command output to a file on either the ACE disk0: or a remote server.

The keywords, arguments, and options are as follows:

disk0:[path/]filename—Specifies that the file destination is the disk0: file system of the current context. If you do not provide the optional path, the ACE copies the file to the root directory on the disk0: file system.

ftp://server/path[/filename]—Specifies the FTP network server and, optionally, the filename.

scp://[username@]server/path[/filename]Specifies the SCP network server and optional file name.

sftp://[username@]server/path[/filename]—Specifies the SFTP network server and, optionally, the filename.

tftp://server[:port]/path[/filename]—Specifies the TFTP network server and, optionally, the filename.

The output of the show tech-support command is in gzip format. We recommend that you include the .gz extension in the filename so that it can be easily unzipped from the destination file system.

Examples

The following example shows the show tech-support command output:
