How to monitor globally distributed sites
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 datacenters.
Geomaps in Citrix Application Delivery Management (Citrix 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 sections explain how you can monitor datacenters in Citrix ADM.
Monitoring globally distributed sites in Citrix ADM
Citrix ADM site is a logical grouping of Citrix Application Delivery Controller (Citrix 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. Citrix ADM manages and monitors all Citrix ADC instances connected to all sites. You can use Citrix ADM to monitor and collect syslog, AppFlow, SNMP, and any such data originating from the managed instances.
Geomaps in Citrix 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 click Networks on the menu and this displays the Instances Dashboard for a visual representation of the sites created on the world map.
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.
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.

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 Citrix ADC instances in Citrix ADM. You must also add the instance to the site, add an agent, and bind the agent to the site. Citrix ADM then recognizes the site that the Citrix ADC instance and the agent belong.
For more information on adding Citrix ADC instances, see Adding Instances.
To create sites:
Create sites before you add instances in Citrix ADM. Providing location information allows you to locate the site precisely.
- In Citrix ADM, navigate to Networks > Sites, and click Add.
On the Create Site page, update the following information, and click Create.
- Site Type. Select Data Center.
Note: The site can function as the primary data center or as a branch. Choose accordingly.
Type. Select AWS as the cloud provider from the list.
Note: Check the Use existing VPC as a site box accordingly.
Site Name. Type the name of the site.
Search Location. Type the name of the city. Click Get Location to place the site precisely at the location.\ The City, Zip code, Region, Country, Latitude and Longitude fields are filled in automatically.
- Click Create to create a site in Bangalore.
To add instances and select sites:
After creating sites, you must add instances in Citrix ADM. You can select the previously created site, or you can also create a site and associate the instance.
In Citrix ADM, navigate to Networks > Instances > Citrix ADC.
Select the VPX, and click Add.
On the Add Citrix ADC VPX page, type the IP address and select the profile from the list.
Select the site from the list. You can click the Add button next to Site field to create a site or click the Edit button to change the details of the default site.
Click the right arrow and select the agent from the list that displays.
After choosing the agent, you must associate the agent with the site. This step allows the agent to be bound to the site. Select the agent and click Attach Site.
- Select the site from the list and click Save.
Optionally, you can enter key and value fields for Tags.
You can also attach an agent to a site by navigating to Networks > Agents.
To associate a Citrix ADM agent with the site:
In Citrix ADM, navigate to Networks > Agents.
Select the agent, and click Attach Site.
You can associate the site and click Save.
Citrix ADM starts monitoring the Citrix ADC instances added in Bangalore site along with the instances at the other two sites as well.
