NetFlow: Application Templates

For NetFlow analysis, applications are categorized based on the source address, destination address, source port, destination port, and protocol values in the flow record. The port and protocol values are defined in preconfigured templates and matched with the list of applications.

Site24x7 provides a list of such application templates, which contain preconfigured values. These values are matched with the applications, protocols, and ports and are associated with the template for simplified analysis.

In this doc, we'll cover:

From the Site24x7 web client, navigate to Network > NetFlow > Application Templates to view these templates.

This tab lists the preconfigured application templates along with their rule count.

Number of rules

Displayed next to each application template is the number of rules associated with that template; the rules differ by port and protocol.

Click on a template’s name to view its rules.
