Monitor Globally Distributed Data Centers

Nov 21, 2016

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 NetScaler MAS provides you with a graphical representation of your datacenters and breaks down your network monitoring experience by geography. With geomaps, you can visualize your network instance distribution by location and monitor network issues.

For example, if you have network instances deployed in three datacenters in Santa Clara (USA), Bangalore (India), and Kingston (Australia), the geomap on the Infrastructure > Dashboard page provides a visual representation of these datacenters on the world map as shown in the image below. The blue markers represent the cities where the network instances are deployed.

When you hover your mouse pointer over a marker (for example, Santa Clara), you can view the high-level details of the number of instances deployed at that location. In the following image, there are twenty instances deployed at Santa Clara. You can also view the number of critical and major events raised on the instances at that location.

Click the marker on Santa Clara to view the list of critical and major events raised on the instances located here as shown in the image below.

Click the Instances tab to view the IP address of each network instance, the type of instance, such as NetScaler VPX or NetScaler SDX, and the number of events raised on an instance.

How to Configure Geomaps

Before configuring a data center that you can view on geomaps, you must create IP blocks, so that NetScaler MAS can recognize which data center an instance belongs to when it is added to the NetScaler MAS server.

A NetScaler MAS data center is a logical grouping of NetScaler instances in a specific geographical location. You can have several NetScaler instances within a data center that can be monitored and managed by the NetScaler MAS server. You can use the NetScaler MAS server to manage data such as syslog, appflow, and SNMP etc from the managed instances.

Before configuring a data center, you must create IP blocks, so that NetScaler MAS can recognize which data center an instance belongs to when it is added to the NetScaler MAS server. For example, if the instance’s IP address falls within the range of an IP block associated with Data Center 1, the instance being added to NetScaler MAS is known to be located in Data Center 1.

To create an IP block

  1. Navigate to Infrastructure > Data Centers > IP Blocks, and then click Add.
  2. In Configure IP Blocks, sspecify the name of the IP block and the starting and ending IP addresses in the IP block. Then, specify the country, region, and city. You might have to specify the latitude and longitude of the city if it is not already saved in the geo database.
  3. Click Create to finish.

To configure a data center

  1. Navigate to Infrastructure > Data Centers, and then click Add.
  2. In Configure Data Center, specify the name of the data center.
  3. From the list of available IP blocks, select one or more blocks to associate with the data center.
  4. Click Create.
