Monitoring 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.
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 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.
-
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, or 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 network interface cards 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 status of whether inventory from the instance is completed or whether reboot is in progress.
-
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.
-
Viewing 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.
Pinging 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.
Tracing 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.
Rediscovering 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.
