Alarm Manager

The automatic alarm system is an essential part of Trimble 4D Control Server. If one of the modules in the Trimble 4D Control Server system reports that it is in a status defined as an alarm condition, it issues an alarm message. When this status disappears, it issues another message. The Alarm Manager module receives the messages and, if configured accordingly, reacts to them with performing a user-defined action.

Alarms come in several levels (information, warning, alert), some of them requiring to be acknowledged.

The Alarm Manager module is available from the root item of the Tree view item. While it is possible to use only one Alarm Manager module for the whole system, Trimble recommends to set up one Alarm Manager module for each computer participating the distributed environment.

For a specified alarm condition, Alarm jobs define the actions that are performed, if this condition occurs or disappears. To define individual actions for a group of selected modules, you may use the System properties to specify module groups first.

The Alarm Manager module organizes its tasks in "jobs". Each job defines

• the alarm condition: selectable from all conditions or module-dependent,
• the alarm action: you can select group-dependent actions,
• the condition status (did the condition occur or disappear?),
• an action delay (optional).

Additionally, the following applies:

• If the Alarm module is loaded, its jobs are enabled; if the module is unloaded, the jobs stop executing their tasks.
• You can pause any job by selecting the None action.
• You can define several action settings depending on Alarm groups.
  

  To define a module group, you select specific modules from all modules currently added to the system.

  Tip - If you add new modules to the system later, they are by default members of the All group. For all other groups, make sure to add new modules to the matching group(s).

  Many Trimble products allow one to make use of module groups, when setting up alarm jobs. For all alarm jobs, the same module groups are available. When defining an alarm job, you define for each module group the specific action settings.

The Alarm Manager module can run multiple jobs. For example, to invoke two different actions for the same alarm condition, set up two jobs.

Modules that trigger an alarm message and can be selected for alarm jobs.

Actions Trimble 4D Control Server supports to perform after the alarm is issued.

Settings and module views

When the module is first being added, the Alarm Manager Properties dialog appears. It lets you define and select Alarm Manager module configurations. Each configuration holds one or several Alarm jobs, which you define first, before the Alarm Manager module can start executing its tasks. You also may remove a configuration or an Alarm job from here, if you do not need them anymore. You can add further settings and jobs to the selected Alarm configuration at any time.

The module displays the Alarm Status, History, and All Alarms History module-view pages.

In the Tree view, an Alarm Manager module is represented by its configuration name and a status-identifying icon.

Logging into the database

All actions of the Alarm Manager module are logged into the central database. The database contains the following tables referring to the Alarm Manager system:
