Flap Handling

When a flapping service or host is detected for the first time, SONARPLEX will:

• Create an event log message indicating that the service or host is flapping.
• Add a non-persistent comment to host or service about it.
• Send a "flapping start" notification for the host or service to appropriate contacts.
• Suppress all other notifications for the service or host.

When flapping for service or host stops, SONARPLEX will:

• Create an event log message indicating that the service or host has stopped flapping.
• Delete the comment that was originally added to the service or host when it started flapping.
• Send a "flapping stop" notification for the host or service to appropriate contacts.
• Start to send other notifications for the service or host.

Utilities

Utitlities with self-explaining names can be used to manage flap detection immediately without restarting monitoring process.
