Using the Health statistics report, you can check the
availability statistics of your system entities and monitor the health of your
system.
What you should know
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.
Availability is expressed as
a percentage in the report pane.
Procedure
-
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.
Results
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.
Example
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.
