Welcome to our NetScaler Application Delivery Manager (ADM) FAQs. If you don’t see what you’re looking for, get in touch and we can give you a straight answer to your question.

What is NetScaler ADM?

NetScaler ADM is a centralised solution for the management, monitoring and troubleshooting of all your NetScaler appliances. It provides a single pane of glass view where you can perform all the management tasks. Such as adding new devices, edit configurations, backup/restore configurations, monitor traffic, report, alert and more.

NetScaler ADM can also be configured for AppFlow reporting, receiving HDX/ICA AppFlow traffic from NetScaler devices.

What does NetScaler ADM do?

NetScaler ADM is a virtual appliance that runs on NetScaler Hypervisor, VMware ESXi, and Linux KVM.

It collects the following information about web applications and virtual desktop traffic and provides visibility of:

  • User session level information
  • Webpage performance data
  • Database information flowing through the NetScaler instances and provides actionable reports.

NetScaler ADM enables IT administrators to troubleshoot and proactively monitor customer issues in a matter of minutes.

How does NetScaler ADM work?

Once the NetScaler ADM server is installed and licenced appropriately you can connect using a supported browser over port 80 or 443. From this browser, you can perform all the management, monitoring and troubleshooting you need.

For example, you can add instances (NetScaler appliances ) to the ADM server by adding their management IPs (for NetScalers this is the NSIP).

Once these devices are added and discovered by the ADM server, it uses NITRO calls, SNMP, SSH, and SCP protocols to initiate the transfer of information such as appliance inventory, licence, certificate details etc. It can also perform configurations and firmware updates.

All the information is processed by the NetScaler ADM server and stored in the internal database for current and future reporting/use.

What are NetScaler ADM prerequisites?

NetScaler ADM is a virtual appliance that can be installed on the following hypervisors, NetScaler Hypervisor, Microsoft Hyper-V, VMware ESXi and Generic KVM

The requirements for an install are 32GB memory, 8 vCPU’s and at least 120 GB disk storage depending on what you want to record and how long you want to keep it.

The recommendation is that you add a second disk for your data storage at the initial time of installation. The size of this storage is dependent on several factors such as the number of instances, type of traffic, NetScaler licences etc.

See all system requirements here, or contact us at hello@clouddnagroup.com for more specific information.

How to install NetScaler ADM?

Installation of NetScaler ADM depends on your needs, what you want to record, how long you want to keep it, and the available hypervisor. The basic requirement for an on-premises install is 32GB memory, 8 vCPU’s and at least 120 GB disk storage.

What is a NetScaler ADM agent?

A NetScaler ADM agent is an intermediary ADM device between the main NetScaler ADM server (either on-premises or in the cloud) and the discovered instances at different datacentres or sites.

The agent is used when remote instances require management and it collects the local instances information and passes the data back to the main NetScaler ADM

What does NetScaler ADM agent do?

The agent is used when remote instances require management. The agent collects appropriate information from the local instances and passes the data back to the main NetScaler ADM server.

The NetScaler ADM agent provides a local communication point for instances which in turn communicates with the main ADM Server. This means only the agent communicates with the main ADM server minimising WAN traffic and firewall port configurations.

What is the application security dashboard?

The application delivery dashboard is an overview of the licenced and discovered applications monitored by the ADM server. It shows the security attack information these applications have endured, such as sync attacks, DNS flood attacks and more.
