Sometimes an error message may indicate an issue with one of the virtual machines in the appliance. To check their status,
go to the System Configuration page and select an Instance view of either the SD-WAN or NetScaler subsystems. For
example, the SD-WAN page is shown below:
A fully active instance will show a green circle for VM State, Instance State, and Licensed.
Your appliance may have more instances present than are licensed; ignore the unlicensed instances.
If the VM State or Instance State of the remaining instances are not green, use the “Rediscover” action to attempt to
bring these instances back into operation.
You can also get detailed information for each instance, as shown below:
Every instance should have a Status of “Inventory from SD-WAN Instance completed.
Every instance should be running the same version of the software.
Every instance should have the netmask (255.255.255.0) and gateway (169.254.0.20).
Instances that show an uptime shorter than other instances have rebooted since the last whole-system reboot.

Sometimes it is useful to log into the NetScaler instance to check its status or do configuration. You can log into the
NetScaler instance from the NetScaler Instances page of the System Configuration view, as shown below. Click the IP
Address link.
You can also log into the NetScaler instance directly from your browser if you know its IP address on the management port
(port 0/1).
Once logged in, you will see the NetScaler GUI, which identifies itself as NetScaler VPX at the top of the page.
This is the standard NetScaler user interface. Using monitoring features is safe. Configuration changes should be made with
caution, as the SD-WAN 4000/5000 makes undocumented assumptions about how the NetScaler instance is configured.

The ping and traceroute utilities are not available on the accelerator instances, as they are on other SD-WAN products.
Instead, you can use the equivalent features on the NetScaler instance, using the Diagnostics page as shown below.
These features will work over your external network and on the appliance’s internal subnets.

Unlike the SD-WAN Dashboard, the System Dashboard page is devoted largely to hardware monitoring.
The System Health tables show a status summary, with a Details link for expanded information in graphical form.
The Events tables show a status summary, with a Show Events link to see the related log entries.
The system below shows a conditions worth investigating:
The power supply was struggling, as can be seen in both the Hardware Sensors Summary and the System Health Events
log. (The count in the System Health Events heading shows that there was only one event, the Date field shows that it
