Introduction

This report measures processor capacity usage and is broken down into various activities over selected period of time. Processor occupancy needs to be carefully monitored to ensure the hardware is operating within accepted tolerances.

Although Call Processing itself is protected through process encapsulation within the Avaya Aura Communication Manager application, this only provides priority access to the processor.

System faults can push processor occupancy to a point where updating adjunct applications and call processing is slowed, leading to unexpected behavior of these applications.

This report can be used in conjunction with Availability Management to immediately identify and notify this type of incident, allowing engineers to take steps to reduce loading before business is impacted.

Uses

This report provides an application view of processor performance and tracks capacity of:

• Static processing
• Call processing
• System Management

Which is useful for:

• Ensuring processor occupancy is within accepted tolerances.
• Identifying system faults, when used in conjunction with Availability Management, before they become business impacting.

Example

In this example, processor occupancy is within recommended levels. If total occupancy exceeds 70%, engineering teams will be immediately notified.

VSM has a very small footprint when compared to other management applications, as shown by the System Management occupancy (light blue section) in the image below.
