Monitor globally distributed sites

Last published : Sep 21, 2026
As a network administrator, you might have to monitor and manage network instances deployed across geographical locations. However, it is not easy to gauge the requirements of the network when managing network instances in geographically distributed data centers.
Geomaps in NetScaler® Application Delivery Management (ADM) provides you with a graphical representation of your sites and breaks down your network monitoring experience by geography. With geomaps, you can visualize your network instance distribution by location and monitor network issues.
The following section explains how you can monitor data centers in NetScaler ADM.
NetScaler ADM site is a logical grouping of Citrix Application Delivery Controller (ADC) instances in a specific geographical location. For example, while one site is assigned to Amazon Web Services (AWS) and another site might be assigned to Azure. Still another site is hosted on the premises of the tenant. NetScaler ADM manages and monitors all NetScaler instances connected to all sites. You can use NetScaler ADM to monitor and collect syslog, AppFlow, SNMP, and any such data originating from the managed instances.
Geomaps in NetScaler ADM provides you with a graphical representation of your sites. Geomaps also breaks down your network monitoring experience by geography. With geomaps, you can visualize your network instance distribution by location and monitor all network issues. You can navigate to Infrastructure > Instances page for a visual representation of the sites created on the world map.

Use case

A leading mobile carrier company, ExampleCompany, was relying on private service providers for hosting their resources and applications. The company already had two sites - one at Minneapolis in the United States and another in Alice Springs in Australia. In this image, you can see that two markers represent the two existing sites.  
Use case
The markers also display a number, which shows the number of applications in each site. You can click these markers for more information about each site.

Configuring Geomaps

ExampleCompany decided to create a third site in Bangalore, India. The company wanted to test the cloud by offloading some of their less-critical, internal IT applications to the Bangalore office. The company decided to use the AWS cloud computing services.
As an administrator, you must first create a site, and next add the NetScaler instances in NetScaler ADM. You must also add the instance to the site, add an agent, and bind the agent to the site. NetScaler ADM then recognizes the site that the NetScaler instance and the agent belong.
For more information on adding NetScaler instances, see Adding Instances.
