Network Statistics Extended (NSX)

Tandem Network Statistics Extended (NSX) is a NonStop operating system network

performance monitor that collects and displays processor, process, and Expand process

statistics from other NonStop systems operating in a Tandem network.

NSX monitors and reports high-level, real-time network statistics from multiple network

nodes to one or more locations within that network. In addition, NSX collects and

reports on the busiest processes in each processor in all monitored systems.

How NSX Works

NSX collects performance statistics data with a set of Monitor and Collect processes

operating on selected nodes within the network. A Monitor process in each node reports

statistics for its node to a Collect process, which maintains the statistics in the NSX

database.

You can configure both Monitor and Collect processes on one or more nodes throughout

the network. You can centralize data collection to a single node, or on to groups of

regional nodes, or you can completely distribute it so that each individual node in a

network has its own NSX statistics database. Figure 9-6 illustrates the NSX architecture.
