4 Calendar Server Redundancy Group

The Calendar Server Redundancy Group target is a grouping of all Calendar server agent monitored targets that have identical configuration, characteristics, and functionality. While a single Calendar server instance is vulnerable to the failure of its host or system, a redundant group of Calendar Servers continues to function despite the loss of a Calendar server instance, hiding any such failure from clients, and allowing other Calendar server instances in the group to service the requests.

4.1 Connections

The Connections category provides information about the number of connections made to the Calendar servers.


Note:

For Version 1.0, the evaluation and collection frequency for each metric is every 15 minutes.
