Working with Nodes
•CPU Utilization Chart—Displays the CPU utilization percentage for the
node as a function of time.
To see the exact time and data coordinates for a data point, left-click the data
point. The coordinates are displayed in the format (hh:mm:ss, dd.dd), where:
–
hh:mm:ss is the time for that data point in hours, minutes, and seconds.
–
dd.dd is the CPU utilization percentage for that data point.
The total time displayed in the chart is specified in the Time Window (mins)
field.
New data points are added to the right side of the chart. When the chart
reaches the end of the time window (for example, after 5minutes, if the Time
Window (mins) field is set to 5), new data points continue to be added to the
right side of the chart, while old data points “drop off” the left side of the
chart.
If a poll is missed (for example, as a result of an SNMP timeout), SGM
ignores the missing data point, stops drawing the line, and waits for the next
valid data point to begin drawing the line again.
To scroll left, right, up, or down in the chart, drag the cursor while holding
down Ctrl and the left mouse button.
To zoom in on a section of the chart, drag the cursor while holding down Shift
and the left mouse button.
To reset the chart to the default view and scaling, click Reset.
•Time Average—Displays three color-coded icons, one for each average
calculation: 5 seconds, 1 minute, and 5minutes.
To remove the data for a given average from the chart, click the icon in this
field. To return the data to the chart, click the icon again.
•Reset—If you scrolled or zoomed the chart, resets the chart to the default
view and scaling.
•Grid On—Superimposes a graphic grid on the chart. The grid can make the
data easier to read.
•Grid Off—Removes the graphic grid from the chart.
•Close—Closes the SGM Real-Time Statistics: CPU Statistics window.
•Help—Displays online help for the current window.
