Measure Reference Manual

CLUSTER
The CLUSTER entity provides information about the number of FOX messages sent and received
by all processes on the local system. In this manual, the term FOX refers to:
ServerComponent
Cyclone or VLXFOX II
NonStop K-seriesTorusNet
NonStop S-seriesServernet/FX
A FOX link involves at least two processes on different systems: the linker that initiated the link and
the listener that accepted the link. Because the Measure subsystem can measure only the local
system, the measurement data reflects only one side of each FOX link: that of the linker or the
listener, but not both.
