2.10.10.4 Performance
Statistics
The REPORT NETWORK MANAGER SECONDARY STATISTICS and
REPORT NETWORK MANAGER NETWORK STATISTICS commands are
provided as network diagnostic aids for locating bottlenecks or faulty
secondaries. The REPORT NETWORK MANAGER SECONDARY
STATISTICS command, code 37, returns statistics for a specific secondary
device.
These statistics are counters reflecting the communications between
the
Network
Manager and the secondary
.
Each transaction will update the counters until their maximum value is
reached.
Then the command must be issued to reset the counters.
Y
ou may want
to reset the counters before beginning the diagnostic period so that the counts
start
at the zero baseline.
The second command, REPORT NETWORK MANAGER NETWORK
STATISTICS — code 38, returns statistical counters for an specific media
channel.
The counts reflect the activity between
the Network Manager and all
secondary
addresses. Like the secondary statistics counters,
these counters are
not incremented after reaching their maximum value and must be reset
explicitly
with the special command sequence.
The
REPORT HIU ST
A
TUS command returns the connection status of the HIU
and statistics on network performance. The statistics are counts for Network
Manager
to HIU communications. The counters are not
updated after reaching
their
maximum value and must be explicitly reset.
