NetScaler discovery is failing for one particular device. What could be the cause?

For successful NetScaler discovery, the SNMP Manager list must be empty or Command Center must be listed as one of the SNMP Managers. Verify the SNMP Managers configured on the device.

Is it possible to view the device label as a host name or system name instead of as an IP Address?

Yes. In Administration > Server Settings change the Device Label value to display the System Name/Host Name.

Which IP address should I use to discover an SDX device?

Use the SVM IP address to discover the SDX device in Command Center.

When I discover a CloudBridge Advanced Platform by using the SVM IP address, the CloudBridge instances on the CloudBridge Advanced Platform are not discovered in Command Center?

Only the CloudBridge accelerators on a CloudBridge Advanced Platform are discovered.

Are NAT, SNIP, and MIP based discovery of NetScaler devices supported in Command Center?

Yes. But SNIP and MIP cannot be used for the discovery of a device configured in HA mode.

I changed the credentials of my device; do I have to change the credentials in Command Center also?

Yes, you have to update the credentials in the device profile that is used to discover that device. After you update the profile, you have to rediscover the device.

How can I back up the configuration files, such as ns.conf, for a device?

Command Center backs up the NetScaler configuration(ns.conf, the certificates, and so on) the first time the device is discovered and at regular intervals. By Default, the archive interval is 12 hours. You can back up the configuration files on demand from the page that lists the properties of that device.

Where is the ns.conf file located on my Command Center ?

The file is located on the database as a plain text.

I am trying to discover a NetScaler device with SNMP v3 profile and the discovery fails with the following error message: Problem in finding device HA Mode for this device. For input string: " " . What should I do?

On the NetScaler device, in the SNMP v3 view, verify if you have set the subtree value to 1. If it is not set to 1, then clear the SNMP v3 configuration (SNMP view, SNMP group, and SNMP user) from the NetScaler device. Delete the device from Command Center and re-discover.

We see all the devices that we manage under Device Inventory page on Command Center. When we click on IP addresses in the Device Inventory page a new browser is opened and displays the Netscaler management page over HTTPS. However the we manage all Netscalers over HTTP and not over HTTPS. Is there a way to change from HTTPS to HTTP on Command Center Inventory page in order to access over HTTP.

Answer: This is as per design. The command center initiates only a secure connection to the Netscaler when clicked on the Device Inventory IP addresses. There is no possibility to open in HTTP. Enable secure access under the NSIP settings and this should enable the access to the Netscaler management page from Command Center.

How to change Netscaler device location in Command Center?

The location is defined in the NetScaler > System > SNMP > Change SNMP MIB >Change location.

CLI Command : set snmp mib [-contact <string>] [-name <string>] [-location <string>].

By default the location entry would be POP (Default).

Question: Discovery of few Netscaler devices get stuck with status as  "Started".

This was caused by the MIB location value being greater than 50 characters. Check for the following line in the ns.conf and if the location value is greater than 50 characters then we must reduce the length and run discovery again for this unit.

set snmp mib -contact test@contoso.com -name PRD-NS01 -location "This is where the location information would be displayed" -customID PRD-NS01
