Blue Coat Systems SGOS Version 5.2.2 manual About Health Monitoring Notification

Volume 9: Managing the Blue Coat SG Appliance

For the license expiration metrics, the threshold interval is irrelevant and is set by default to 0. You should set the Warning Threshold to a value that will give you ample time to renew your license. By default, all license expiration metrics have a Warning Threshold of 30 days. By default, the Critical Threshold is configured to 0, which means that a trap is immediately sent upon license expiration.

About Health Monitoring Notification

By default, the Director polls the SG appliances to determine their current state. If the state has changed, Director updates the device status. Other types of notification are also available. Any or all of the following types of notification can be set:

❐SNMP trap: Sends an SNMP trap to all configured management stations.

❐E-mail: Sends e-mail to all persons listed in the Event log properties.

❐Log: Inserts an entry into the Event log. See “Setting Up Event Logging and Notification” on page 15 for more information.

About the General Metrics

The following table lists the metrics displayed in the Maintenance > Health Monitoring > General page. The thresholds for these metrics are user-configurable. See “About Health Monitoring” on page 24 for information about thresholds and alert notification.

All threshold intervals are in seconds.
