Diagnostics calculated over time
The System Status page (Figure 7-5) contains seven diagnostic attributes that are
calculated over time and presented as arrays of four elements (Figure 7-12).
Figu
re 7-12 Diagnostic attributes calculated over time
These attributes are defined in Table 7-5.
The elem
ent arrays represent the following:
• Max: The maximum value measured over the last hour.
• Avg: The mean of a set of values recorded at one second intervals over the last
hour.
• Min: The minimum value measured the last hour.
• Latest: The latest value measured.
If the link has been running for less than one hour, then the values are calculated over
the time that has elapsed since the link was established.
These attributes can be plotted against time, downloaded and reset by using the
Diagnostics Plotter page, as described in Using the diagnostics plotter on
page 7-21.
