MANAGING SYSTEM INVENTORY

Performance

The Intel Server Manager Performance page lets you monitor the performance of various system

objects. You can monitor specific hardware components, such as drives, processors, and

memory, or you can monitor OS components, such as processes or bytes/sec transferred by the

system's Web server. The Performance page includes a graph that displays real-time or historical

data for a counter. You can also acknowledge alerts received for a counter and stop monitoring a

performance counter by deleting it from the list of monitored counters.

In order to monitor a performance counter you must first select the counter, which adds it to the

list of

monitored counters. When you do this you also specify the frequency for polling the item

and set performance thresholds and the number of violations that are allowed before an alert is

generated.

You can set alert actions to trigger notification when a performance counter crosses an upper or

lower threshold a predetermined number of times.

To view a performance graph for a monitored counter

1. Click System, then click Performance.

2. Click Performance graph.

3. From the Counters drop-down list, select the counter you for which want to see a

performance graph.

4. Select View real-time data to display a graph of real-time performance.

Select View historical data to display a graph showing performance over the period you

specified (Keep history) when selecting the counter.

Notes

• The horizontal axis represents time that has passed.

• The vertical axis represents the units you are measuring, such as bytes/sec (when

monitoring file transfers, for example), percentage (when monitoring percentage of the

CPU that is in use), or bytes available (when monitoring hard drive space).

• The line height is not a fixed unit. The height of the line changes relative to the extremes

in the data; for one counter the vertical axis might represent 1 to 100 and for another it

might represent 1 to 500,000. When the data varies across a wide extreme, minimal

changes can appear as a flat line.

• Selecting another counter refreshes the graph and resets the units of measurement.

• Click

to clear and restart the graph.

• Click Reload counters to refresh the list with any new objects, instances, or counters.

To stop monitoring a performance counter

1. Click System, then click Performance.

2. Click Monitored performance counters.
