In the diagram above,
NetSpy
s 01 and 03 transmit all network measurement data to
NetSpy
02, where it is logged to SMF. Because this raw measurement data is sent via the
NetSpy
-to-
NetSpy
interface, no bulk data transfer program is required to provide this central logging of Network SMF data.
In the
NetSpy
SMF data logged on host 02, the SYSID field identifies the host of the
NetSpy
that collected the measurement data on, say, host 01 or 03. For example,
NetSpy
01 collected response time statistics for APPL01 and then transmitted this data to
NetSpy
02. When
NetSpy
02 logs the data to SMF, the SYSID field will identify host 01, the host on which the data was collected. For further information about
NetSpy
-to-
NetSpy
communications, refer to the
NetSpy
documentation.
The
NetSpy
-to-
NetSpy
Communications interface does not create duplicate logging of
NetSpy
data to a single
MICS
system as long as you do not transmit
NetSpy
measurement data to a central site using both
NetSpy
-to-
NetSpy
communications and a bulk data transfer program (or courier system).
