Using the Health statistics report, you can check the availability statistics of your system entities and monitor the health of your system.
By monitoring the health and availability of resources such as server roles, video units, door controllers, intrusion detection panels, and so on, you can identify instabilities and even prevent critical system failures.
What you should know
Availability is expressed as a percentage in the report pane.
- Open the Health statistics task.
Set the query filters for your report:
- Event timestamp
- Define the time range for the query. The range can be defined for a specific period or for global time units, such as the previous week or the previous month.
- Observer entity
- The entity (role, server, unit, and so on) that reported the event.
- Show current health events
- Restrict the search to entities with active health events. Only entities with events that have been active for longer than the specified duration are listed in the report.
- Source entity
- Source entity of the event.
- Source group
- Source entity group of the event. Usually a role or a unit.
- Click Generate report.
The report pane lists the health statistics for the selected entities. If health statistics could not be calculated for a given role or entity, the reason is shown in the Calculation status column:
- One or more events used to calculate availability are currently disabled
- The system administrator needs to select which health events to monitor by configuring the Health Monitor role. For information about selecting which health events to monitor in Config Tool, see the Security Center Administrator Guide.
- One or more servers from the system are offline
- The server hosting the selected role is offline, therefore the health statistics for the role cannot be calculated.
A door controller called Gym was down four times over the last week, producing 90.72% availability. From the report results, you can see that this door controller is a potential concern, and have a maintenance crew come and look at the door.
