9-12 Detecting Changes in Availability
The ability of the SystemAlert module to detect changes in availability provides automatic supervision of your
system. It informs you of disturbing changes in the following areas:
• Devices Configured on a Node
• Processes in Applications Defined on a Node
Each time a device or a process belonging to an application changes status, an alert message is sent to the
SystemAlert window.
For details, refer to Configuring Availability Chapter in the OVNPM Server Guide.
9-13 Detecting Incidents on a File
The ability of the SystemAlert module to detect incidents on a file provides monitoring of the size of files.
Each time a monitored file exceeds designated or default thresholds of related metrics, an alert message is sent to
the Display Server process that will forward it to designate output devices.
For details, refer to Configuring File Scanning chapter in the OVNPM Server Guide.
