Software Availability Manager

Software Availability Manager Functions

SAM has the following functions:
•
Monitor user applications to detect when they fail.
•
Monitor the performance of critical system components—such as disk, CPU, and
memory—to detect performance problems before they cause a crash or data loss.
•
Send messages to the Windows Event Log and notify users, by email, of certain
system-performance conditions.
•
Execute user-specified programs in response to configured alert conditions.

Monitoring Instances and Events

SAM monitors instances and events.
Instances are the system performance elements that you specify to be monitored; for
instance, CPU usage, disk free space, and so on. The list of instances you can monitor
appears on the Express5800/320Ma Monitored Instances tab of the SAM snap-in. (See
"SAM Instances" on page 1-3
specify which instances to monitor by configuring SAM in the MMC console.
An event, in the context of SAM, is a state change in a monitored instance. For
example, available disk space falling below specified limits is an event. You can
configure the instances to generate a warning or alarm and trigger the execution of a
program when the instance reaches a certain value.
For example, you can configure SAM to:
•
Send an email warning (less severe) or alarm (more severe) to members of a
defined email list when available disk space on the system falls to a specified
percentage.
•
Send email notification to members of a defined email list when the available
system memory falls below a specified amount.
•
Execute a program when some specified threshold value is reached.
