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).
