Extra management CPU
If you need better performance for configuration and monitoring of a Citrix ADC MPX appliance, you can allocate an extra management CPU from the appliance’s packet engine pool. This feature is supported on certain Citrix ADC MPX models and all VPX models except the VPX instances that run on Citrix ADC SDX appliances. It affects the output of the stat system cpu and stat system commands.
Supported Citrix ADC MPX models:
- 25xxx
- 22xxx
- 14xxx
- 115xx
- 15xxx
- 26xxx
Note
For Citrix ADC MPX 26xxx models with more than 20 cores, the mandatory extra management CPU feature is enabled by default. For Citrix ADC VPX models, a license that supports atleast 12 vCPUs is required to enable this feature.
Allocate or deallocate an extra management CPU by using the Citrix ADC CLI
At the command prompt, type one of the following commands:
enable extramgmtcpu
disable extramgmtcpu
Note
After you enable and disable this feature, the Citrix ADC appliance displays a warning to restart the appliance, for the changes to take effect.
To show the configured and effective state of an extra management CPU.
At the command prompt, type:
`show extramgmtcpu`
Example
> show extramgmtcpu ConfiguredState: ENABLED EffectiveState: ENABLED
Note
In this example, the show command is entered before restarting the appliance.
Parameter descriptions of commands listed in the command line interface
enable extramgmtcpu
Enables and dedicates extra CPU for management from PE pool.
See also:
disable system extramgmtcpu
show system extramgmtcpu
- disable extramgmtcpu
Disables extra CPU for management and returns it to the PE pool.
See also:
enable system extramgmtcpu
show system extramgmtcpu
- show extramgmtcpu
Displays configured and effective states of the extra management CPU.
Configured and effective state are different if enable extramgmtcpu command has been entered but system is has not been restarted.
See also:
enable system extramgmtcpu
disable system extramgmtcpu
Allocate an extra management CPU by using the GUI
To allocate an extra management CPU by using the GUI, navigate toSystem>Settingsand clickConfigure Extra Management CPU. From theConfigured Statedrop-down menu, selectEnabledand then selectOK.
To check CPU usage, go toSystem>Settings>Dashboard.
Configure an extra management CPU by using the NITRO API
Use the following NITRO methods and formats to enable, disable, and show an extra management CPU.
To enable an extra management CPU:
HTTP Method: POST
URL: http://
Payload: {"systemextramgmtcpu":{}}
curl -v -X POST -H "Content-Type: application/json" -u nsroot:nsroot http://10.102.201.92/nitro/v1/config/systemextramgmtcpu?action=enable -d '{"systemextramgmtcpu":{}}'
To disable an extra management CPU
HTTP Method: POST
URL: http://
Payload: {"systemextramgmtcpu":{}} curl -v -X POST -H "Content-Type: application/json" -u nsroot:nsroot http://10.102.201.92/nitro/v1/config/systemextramgmtcpu?action=disable -d '{"systemextramgmtcpu":{}}'
To show an extra management CPU
HTTP Method: GET
URL: http://
Example
curl -v -X GET -H "Content-Type: application/json" -u nsroot:nsroot http://10.102.201.92/nitro/v1/config/systemextramgmtcpu
Statistics and monitoring
The following examples show the differences in the output of the stat system cpu and stat system commands before and after adding an extra management CPU.
- stat system cpu
This command displays statistics of CPUs.
Here is a sample output before adding an extra management CPU on one of the supported models.
Example output
> stat system cpu CPU statistics ID Usage 8 1 7 1 11 2 1 1 6 1 9 1 3 1 5 1 4 1 10 1 2 1
Here is the output after adding an extra management CPU on the same MPX appliance.
> stat system cpu CPU statistics ID Usage 9 1 7 1 5 1 8 1 11 2 10 1 6 1 4 1 3 1 2 1
2. stat system
This command displays CPU use. In the following example, the output before adding an extra management CPU on one of the supported models is:
Mgmt Additional-CPU usage (%) 0.00
Example output
> stat system Citrix ADC Executive View System Information: Up since Wed Oct 11 11:17:54 2017 /flash Used (%) 0 Packet CPU usage (%) 1.30 Management CPU usage (%) 4.00 Mgmt CPU0 usage (%) 4.00 Mgmt Additional-CPU usage (%) 0.00 Memory usage (MB) 2167 InUse Memory (%) 5.76 /var Used (%) 0
In the following example, the output after adding an extra management CPU on the same MPX appliance is:
Mgmt Additional-CPU usage (%) 0.80
> stat system Citrix ADC Executive View System Information: Up since Wed Oct 11 11:55:56 2017 /flash Used (%) 0 Packet CPU usage (%) 1.20 Management CPU usage (%) 5.70 Mgmt CPU0 usage (%) 10.60 Mgmt Additional-CPU usage (%) 0.80 Memory usage (MB) 1970 InUse Memory (%) 5.75 /var Used (%) 0
