Data Monitoring - Add Server Subnets

Add one or more server subnets to specify the range of server IP address that you want to monitor.

Frequently Asked Questions

• Can I exclude a particular server from the server subnet? After you add a server subnet, you can exclude one or more servers within the specified range of IP addresses by adding an exclusion.
• How should I define a server subnet? Add server subnets that closely align with your server VLAN definitions. A properly-defined server subnet provides the management console with the flexibility that is required to keep a user-defined application up-to-date. When you assign a server subnet to an application, the management console monitors the application as the servers which host the application change.
• Why add an exclusion to a server subnet? To prevent the management console from monitoring particular servers that match the specified server subnet, add an exclusion.
• Why does the management console add matching servers in the Network List? To enable the management console to monitor a multi-tier application where a server initiates client requests to another server, the management console automatically creates a /32 client network for each IPv4 server, respectively. When a monitoring device observes server traffic that matches a specified server subnet, the management console automatically adds the server to the Server List and adds a /32 client network, with the network type you specify, to the Network List.

Property Details

Complete the following fields:

Server Subnet Name

Specify the name of the server subnet as you want it to appear in the management console with a maximum length of 50 characters.

Subnet

Specify the range of server IP addresses to monitor:

IPv4 server subnet

Use the following format for IPv4 addresses: x.x.x.x/n, where x.x.x.x is the IPv4 subnet address in dotted notation and n is the number of bits to use for the mask.

Network Type

Specify the network type that you want the management console to assign to corresponding /32 client networks that are created from matching IPv4 server traffic.

If you do not specify a network type, it is set to Unassigned.
