Detecting High Processor Utilization

A processor overload can lead to unpredictable performance degradations in a filer. To prevent such problems, administrators need to monitor the Processor Utilization parameter on each filer to diagnose whether the filer processor constitutes the performance bottleneck.

1.	In the Status tab, click the NetApp Filer for which you need to check the Processor Utilization, then click:

•	Node > Processor > Processor Utilization (C-Mode)

•	Controller > Processor > Processor Utilization (7-Mode)

to display the current value for the Processor Utilization parameter.

2.	Click the History icon to automatically display a graph that shows the Processor Utilization values collected for a selected parameter during the previous six hours. You can customize the chart and table to show parameter history for different time periods.

GRAPH_Processor_Utilization

Viewing a NetApp Filer's Processor Utilization as a graph

A processor utilization over 80% means that this processor is overloaded and that it constitutes a bottleneck for the filer.

By default, the Processor Utilization parameter will display a warning when reaching 80% and an alert when reaching 90 %. You can easily modify these thresholds in the Thresholds page.
