The Device Statistics Screen
Page 5-22
This read only screen enables the user to monitor the performance of the
managed network. The error statistics provided here can be useful in the
diagnosis of LAN problems.
The counters are updated at each screen refresh.
5.8.1 Screen Mode
The screen operates under three different counting modes, described
below. The screen mode currently in effect is listed in parentheses on the
screen title line. The remaining two modes-in-waiting are listed on the
screen command line. To select another screen mode, invoke it from the
screen command line.
TOTAL 1
In this mode, the counters display totals since the STHI hub’s last reset.
DELTA 2
In this mode, the counters display totals since last screen refresh.
ACCUMULATE 3
In this mode, the screen provides a CLEAR screen command which clears
all counters, enabling the user to monitor network performance from a
user-determined moment. Clear Date and Clear Time fields are
provided to note the moment the counters were reset.
