The OS Performance Report contains the following three reports and is most useful if run over a period of 7 days or more to view trend.

Schedule the report weekly or monthly to manage trends. 

OS Memory Usage Report

Introduction

Depicts the consumption of RAM at the Operating System level, so that it takes into account the true loading including non-Avaya Communication Manager applications.

Useful for identifying hardware capacity constraints. Can be used in conjunction with Availability Management to notify IT support staff of an impending capacity issue, and can be instrumental in preventing large outages.

Uses

Tracks actual consumption over a given period:

  • Trend over time period for forecasting hardware upgrade
  • Identify and act on memory leaks



Video Overview

Example

Example 1

There is a memory leak with an application running on this processor. Urgent action is required to avoid a restart.


Example 2

In this example memory is running at dangerously high levels. An immediate upgrade is highly recommended.


OS Processor Occupancy Report

Introduction

Depicts the loading on the processor at the Operating System level, so that it takes into account the true loading including all applications.

Useful for identifying processor hardware capacity constraints. Can be used in conjunction with Availability Management to notify IT support staff of an impending capacity issue, and can be instrumental in preventing large outages.

Uses

Tracks actual occupancy over a given period:

  • Broken down to User, System and IO wait.
  • Data is cumulative, so the total processor occupancy is readily seen.
  • Trend over time period for forecasting hardware upgrade.

Processor capacity in excess of 70% in a Linux Operating System environment is not recommended and will have a detrimental effect on the performance of the application.


Video Overview

Example

The Processor at the top is running well within manufacturer recommendations. The processor at the bottom is hitting 100% occupancy and should be upgraded to more powerful hardware.

OS Free Disk Space Report


Introduction

Depicts the storage on the Hard Disc taken at Operating System level, so that it takes into account the true loading including non-Avaya Communication Manager applications.

This report is best if run for a period of 2 days or more.

Uses

Useful for identifying hardware capacity constraints. Can be used in conjunction with Availability Management to notify IT support staff of an impending capacity issue, and can be instrumental in preventing large outages.

This report tracks actual storage over a given period:

  • Broken down to partition
  • Trend over time period for forecasting hardware upgrade

Example

The HDD at the top is running well within manufacturer recommendations. The HDD at the bottom still has plenty of capacity but consideration should be given for upgrading to larger hardware.
