Monitoring Citrix NetScaler 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 NetScaler instance, you can perform various tasks to monitor the Citrix NetScaler instance.
Viewing 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 NetScaler instances pane to view details, such as the instance name and IP address, CPU and memory utilization, number of packets received and transmitted on the instance, the 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 NetScaler Configuration, and then click Instances. Note: You can also view the properties of a VPX instance from the Home tab.

-
Viewing the Running and Saved Configuration of a Citrix NetScaler instance
By using the Management Service you can view the currently running configuration of a Citrix NetScaler instance. You can also view the saved configuration of a Citrix NetScaler instance and the time when the configuration was saved.
To view the running and saved configuration of a Citrix NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the Citrix NetScaler instances pane, click the Citrix NetScaler 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 NetScaler Running Config window or the NetScaler Saved Config window, you can view the running or saved configuration of the Citrix NetScaler instance.
Pinging a Citrix NetScaler instance
You can ping a Citrix NetScaler instance from the Management Service to check whether the device is reachable.
To ping a Citrix NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the Citrix NetScaler instances pane, click the Citrix NetScaler instance you want to ping, and then click Ping. In the Ping message box, you can view whether the ping is successful.
Tracing the Route of a Citrix NetScaler instance
You can trace the route of a packet from the Management Service to a Citrix NetScaler instance by determining the number of hops used to reach the instance.
To trace the route of a Citrix NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the Citrix NetScaler instances pane, click the Citrix NetScaler instance you want to trace, and then click TraceRoute. In the Traceroute message box, you can view the route to the Citrix NetScaler.
Rediscovering a Citrix NetScaler instance
You can rediscover a Citrix NetScaler instance when you need to view the latest state and configuration of a Citrix NetScaler 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 NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the Citrix NetScaler instances pane, click the Citrix NetScaler instance you want to rediscover, and then click Rediscover.
- In the Confirm message box, click Yes.
