Monitor Citrix ADC instances
A high-level view of the performance of the appliance and the VPX instances provisioned on the appliance are displayed on the Monitoring page of the Management Service user interface. After provisioning and configuring the Citrix ADC instance, you can perform various tasks to monitor the Citrix ADC instance.
View the properties of VPX instances
The Management Service user interface displays the list and description of all the VPX instances provisioned on the SDX appliance. Use the Citrix ADC instances pane to view details, such as the instance name and IP address, CPU and memory utilization, throughput and total memory assigned to the instance.
Clicking the IP address of the VPX instance opens the configuration utility (GUI) of that instance in a new tab or browser.
To view the properties of VPX instances
-
On the Configuration tab, in the left pane, expand Citrix ADC Configuration, and then click Instances. Note: You can also view the properties of a VPX instance from the Home tab.
-
In the Citrix ADC instance pane, you can view the following details for the Citrix ADC instance:
- Name: The host name assigned to the Citrix ADC instance while provisioning.
- VM State: The state of the virtual machine.
- Citrix ADC State: The state of the Citrix ADC instance.
- IP Address: The IP address of the Citrix ADC instance. Clicking the IP address opens the GUI of this instance in a new tab or browser.
- Rx (Mbps): The packets received on the Citrix ADC instance.
- Tx (Mbps): The packets transmitted by the Citrix ADC instance.
- HTTP Req/s: The total number of HTTP requests received on the Citrix ADC instance every second.
- CPU Usage (%): The percentage of CPU utilization on the Citrix ADC.
- Memory Usage (%): The percentage of memory utilization on the Citrix ADC.
-
Click the arrow next to the name of a Citrix ADC instance to view the properties of that instance. You can also click Expand All to view the properties of all the Citrix ADC instances. You can view the following properties:
- Netmask: The netmask IP address of the Citrix ADC instance.
- Gateway: The IP address of the default gateway, the router that forwards traffic outside of the subnet in which the instance is installed.
- Packets per second: The total number of packets passing every second.
- NICs: The names of the NICs used by the Citrix ADC instance, along with the virtual function assigned to each interface.
- Version: The build version, build date, and time of the Citrix ADC software currently running on the instance.
- Host Name: The host name of the Citrix ADC instance.
- Total Memory (GB): The total memory being assigned to the Citrix ADC instance.
- Throughput (Mbps): The total throughput of the Citrix ADC instance.
- Up Since: The date and time since when the instance has been continuously in the UP state.
- SSL Chips: The total number of SSL chips assigned to the instance.
- Peer IP address: The IP address of the peer of this Citrix ADC instance if it is in an HA setup.
- Status: The status of the operations being performed on a Citrix ADC instance, such as the status of whether the inventory from the instance is completed.
- HA Master State: The state of the device. The state indicates whether the instance is configured in a standalone or primary setup or is part of a high availability setup. In a high availability setup, the state also displays whether it is in primary or secondary mode.
- HA Sync Status: The mode of the HA sync status, such as enabled or disabled.
- Description: The description entered while provisioning the Citrix ADC instance.
Notes:
From release 13.0 build 79.x, when an ADC instance goes out of service due to authentication failure, the instance state color changes to gray if the following conditions are met:
- The ADC instance password is changed directly using the instance CLI.
- The password doesn’t match the instance admin profile password stored in the Management Service.
- The previous session is lost after you reboot the instance for the first time.
Typically, when an instance goes out of service, the instance state color is yellow.
To recover the instance, do one of the following:
- From the instance CLI, modify the password of the instance to match the password in the admin profile of the instance. Then rediscover the instance from the Management Service.
- Create an admin profile with the same password as the current password of the ADC instance. Then, update the ADC instance with the new admin profile.
View the running and saved configuration of a Citrix ADC instance
By using the Management Service you can view the currently running configuration of a Citrix ADC instance. You can also view the saved configuration of a Citrix ADC instance and the time when the configuration was saved.
To view the running and saved configuration of a Citrix ADC instance
- On the Configuration tab, in the left pane, expand Citrix ADC Configuration, and then click Instances.
- In the Citrix ADC instances pane, click the Citrix ADC instance for which you want to view the running or saved configuration.
- To view the running configuration, click Running Configuration, and to view the saved configuration, click Saved Configuration.
- In the Citrix ADC Running Config window or the Citrix ADC Saved Config window, you can view the running or saved configuration of the Citrix ADC instance.
Ping a Citrix ADC instance
You can ping a Citrix ADC instance from the Management Service to check whether the device is reachable.
To ping a Citrix ADC instance
- On the Configuration tab, in the left pane, expand Citrix ADC Configuration, and then click Instances.
- In the Citrix ADC instances pane, click the Citrix ADC instance you want to ping, and then click Ping. In the Ping message box, you can view whether the ping is successful.
Trace the route of a Citrix ADC instance
You can trace the route of a packet from the Management Service to a Citrix ADC instance by determining the number of hops used to reach the instance.
To trace the route of a Citrix ADC instance
- On the Configuration tab, in the left pane, expand Citrix ADC Configuration, and then click Instances.
- In the Citrix ADC instances pane, click the Citrix ADC instance you want to trace, and then click TraceRoute. In the Traceroute message box, you can view the route to the Citrix ADC.
Rediscover a Citrix ADC instance
You can rediscover a Citrix ADC instance when you need to view the latest state and configuration of a Citrix ADC instance.
During rediscovery, the Management Service fetches the configuration. By default, the Management Service schedules devices for rediscovery once every 30 minutes.
To rediscover a Citrix ADC instance
- On the Configuration tab, in the left pane, expand Citrix ADC Configuration, and then click Instances.
- In the Citrix ADC instances pane, click the Citrix ADC instance you want to rediscover, and then click Rediscover.
- In the Confirm message box, click Yes.
