Distributed mode

How does the distributed infrastructure work?

Appliances hosting only the sniffer component of Performance Vision are called "pollers".
The appliance hosting the components in charge of collecting, merging and integrating the data from the pollers into a single database is called "collector". The collector appliance may also host one sniffer component.

The pollers listen and analyze the network traffic.
The collector fetches data from the pollers, integrate them in the database, and then provides an access to the data through the Web UI.

When is data being merged / segregated?

 The data is merged (i.e. the data is integrated in the views with no consideration for the poller, which has captured it) in:

• Business Critical Application Dashboard
• Business Critical Network Dashboard
• Application dashboards
• Graphs (performance, bandwidth, matrix)
• Comparison tables (Client / Server, Network performance, Application performance)
