3 Monitor management
Monitor management in APM allows you to collect performance indexes, health statuses, and
availability of applications, and provides analysis and statistics reports based on this information in
various views. Important concepts and terms in monitor management include:
MonitorEmploys a background program to collect application index data by using a set of
access parameters and to analyze the health status and availability for the application.
Host monitorOrganizes applications by host and displays the availability and the health status of
each application.
Class monitorOrganizes applications by class and type and displays the health status of each
application type.
Custom ViewDisplays the performance and health status of monitored applications.
Application monitor
All monitors in APM are defined as application monitors. APM provides the ability to query, add, modify,
and delete the application monitors, as well as the ability to customize the application monitor list,
manage/unmanage an application monitor, poll the monitored applications, and view associated
applications. An application monitor has the following statuses:
Management statusWhether APM attempts to collect monitor indexes from the target application.
The state can be Managed or Unmanaged. For applications in Managed state, APM attempts to
collect their monitor indexes in each polling period. For applications in Unmanaged state, APM
does not collect their monitor indexes. By default, the management status of an application is
Managed.
AvailabilityState of the connection between the target application and APM. Available states
include:
AvailableAPM can connect with the target application and collect the specified monitored
indexes.
InaccessibleAPM can connect with the target application but cannot collect the specified
monitored indexes. This status can trigger a critical alarm.
UnavailableAPM cannot connect with the target application. This status can trigger a critical
alarm.
UnmanagedThe target application is not monitored by APM. If the management state is
Unmanaged, the availability of the application also becomes Unmanaged.
Health StatusEvaluation result of the target application. Available states include:
HealthyThe application is available and all indexes collected by APM do not meet the
condition of a Level-1 threshold.
MinorThe application is available but APM cannot collect partial monitored indexes. This
health status can trigger a minor alarm.
MajorThe application is available and the monitored indexes collected by APM meet the
condition of a Level-1 threshold. This health status can trigger a major alarm.
