The Performance View displays monitoring point performance statistics gathered by SPECTRUM. These statistics include load, error rate, frame rate and collision rate. The banner across the top of the Performance View provides information about the monitoring point. The border color of the banner indicates the device status. The banner area contains the following fields:

Name

The user-defined or default name of the model.

Location

The location of the device as entered in the Creation dialog box when the model was created. If no location has been specified, this field displays the model name of the SPECTRUM location view containing the device.

System Up Time

The time, displayed in days+hours:minutes:seconds, that the device has been on-line.

The Performance View includes a multi-attribute line graph that shows network load in green, frame rate in blue, percent errors in orange and the percent collisions in yellow. For the IRM2 and IRM3 hubs, the number of active users is shown in brown.

Table 6-1displays the categories of information supplied by the Performance View.
