Monitor 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 NetScaler instance, you can perform various tasks to monitor the NetScaler 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 NetScaler 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 NetScaler Configuration, and then click Instances. Note: You can also view the properties of a VPX instance from the Home tab.
-
In the NetScaler instance pane, you can view the following details for the NetScaler instance:
- Name: The host name assigned to the NetScaler instance while provisioning.
- VM State: The state of the virtual machine.
- NetScaler State: The state of the NetScaler instance.
- IP Address: The IP address of the NetScaler instance. Clicking the IP address opens the GUI of this instance in a new tab or browser.
- Rx (Mbps): The packets received on the NetScaler instance.
- Tx (Mbps): The packets transmitted by the NetScaler instance.
- HTTP Req/s: The total number of HTTP requests received on the NetScaler instance every second.
- CPU Usage (%): The percentage of CPU utilization on the NetScaler.
- Memory Usage (%): The percentage of memory utilization on the NetScaler.
-
Click the arrow next to the name of a NetScaler instance to view the properties of that instance. You can also click Expand All to view the properties of all the NetScaler instances. You can view the following properties:
- Netmask: The netmask IP address of the NetScaler 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 NetScaler instance, along with the virtual function assigned to each interface.
- Version: The build version, build date, and time of the NetScaler software currently running on the instance.
- Host Name: The host name of the NetScaler instance.
- Total Memory (GB): The total memory being assigned to the NetScaler instance.
- Throughput (Mbps): The total throughput of the NetScaler 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 NetScaler instance if it is in an HA setup.
- Status: The status of the operations being performed on a NetScaler 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 NetScaler instance.
Notes:
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 NetScaler instance
By using the Management Service you can view the currently running configuration of a NetScaler instance. You can also view the saved configuration of a NetScaler instance and the time when the configuration was saved.
To view the running and saved configuration of a NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the NetScaler instances pane, click the 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 NetScaler instance.
Ping a NetScaler instance
You can ping a NetScaler instance from the Management Service to check whether the device is reachable.
To ping a NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the NetScaler instances pane, click the NetScaler 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 NetScaler instance
You can trace the route of a packet from the Management Service to a NetScaler instance by determining the number of hops used to reach the instance.
To trace the route of a NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the NetScaler instances pane, click the NetScaler instance you want to trace, and then click TraceRoute. In the Traceroute message box, you can view the route to the NetScaler.
Rediscover a NetScaler instance
You can rediscover a NetScaler instance when you need to view the latest state and configuration of a 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 NetScaler instance
- On the Configuration tab, in the left pane, expand NetScaler Configuration, and then click Instances.
- In the NetScaler instances pane, click the NetScaler instance you want to rediscover, and then click Rediscover.
- In the Confirm message box, click Yes.
