Checking the Status of Services
The Applications: Services page displays services that either you or plug-ins specify and services related to
them by dependency (either as dependents or depends-on).Target states of protected services for the Primary
and Secondary can be specified and are typically Running on the active and Stopped on the passive nodes.
Services are protected if they are set to Running or Automatic, and are otherwise logged as unprotected.The
status shows both the target and actual state for both Primary and Secondary nodes and Failure Counts for
both nodes.
Performance Monitoring
Performance Monitoring describes how vCenter Server Heartbeat monitors system and application attributes
to prevent an unexpected system or application failure.
vCenter Server Heartbeat monitors select application attributes to ensure that the application is performing as
it should within configured thresholds. vCenter Server Heartbeat uses Rules that were automatically configured
during Setup to monitor those attributes. Should an attribute exceed predefined thresholds, vCenter Server
Heartbeat can take pre-emptive action to restart the application, restart the service, or initiate a failover.
Rules
The Applications: Rules page provides a list of rules with their current status and the ability to edit and check
rules.
The following plug-ins implement the rules listed.
