The data collector must examine your management station’s capabilities to
determine what is appropriate for the resource setting that you select. The
capabilities test begins when you click on the
Apply changes button. You will
see a screen listing some statistics about the test. Data collection will stop
during the test, and your management station may run slowly When the test
is complete (approximately four minutes), your resource settings will be in
effect.
Troubleshooting Traffic Monitor
There may be times when your Traffic Monitor gauges are not registering any
data (you see no gauge needles), or one or more segments in the histogram
may go gray. Some of the reasons this may occur are:
■ No Known Segments—If there are no known segments for the selected
network, the gauges will not have needles or threshold indicator colors.
The Selected Segment list box will be empty.
■ Data Not Current—If the data is not current, the gauges will not have
needles, the attribute values are grayed out, and the segment bars in the
histogram are shades of gray. Darker shades of gray indicate more serious
problems with that segment.
