Alarm Detection(4.2)
An Alarm Detection configuration enables you to define criteria for the generation of alarm messages. You select a condition, or combine a set of conditions, that within specific limits, generate an alarm message. To monitor the system alarms, you use the Usage Engine web interface. You can send alarm messages to SNMP monitoring systems, as well.
Alarm Detection Buttons
The contents of the button panel may change depending on which configuration type has been opened in the currently displayed tab. Alarm Detection uses the standard buttons that are visible for all configurations.
There is one button that is specific for Alarm Detection.
Button | Description |
|---|---|
Workflow Alarm Value Names | To define a variable to use in the APL code, see the https://infozone.atlassian.net/wiki/spaces/UEPE4D/pages/107447284 , and the section below, Workflow Alarm Value for further information. |
Defining an Alarm Detection
An Alarm Detection definition is made up of:
A condition, or a set of conditions, see the section below, Alarm Conditions
An object such as host, pico instance, or workflow, that the alarm should supervise
The parameter that you want the alarm to supervise, for example, Statistics value
Time and value limits of supervision
To create a valid alarm detection configuration make sure that:
The Alarm Detection includes at least one condition.
Two conditions within an alarm guard the same object: host, pico instance, or workflow.
Two conditions are set to the same time interval criteria.
To define an alarm
Create an Alarm Detection configuration by clicking the Alarm Detection button from the Configuration menu.
Click on the Edit menu and select the Validate option to check if your configuration is valid.
Click on the Edit menu and select the Workflow Alarm Value Names option to define a variable you can use in the APL code, see https://infozone.atlassian.net/wiki/spaces/UEPE4D/pages/107447284, and in the Workflow Alarm condition, see the section below, Workflow Alarm Value.
Enter a statement that describes the Alarm Detection that you are defining in the Description field.
Select the importance priority that the alarm should have in the Severity drop-down list.
At the bottom of the Alarm Detection configuration, click the Add button.
The Add Alarm Condition dialog box opens.
Select a condition in the Alarm Condition drop-down list.
Alarm Conditions
The Alarm conditions enable you to define specific situations or events for which you want the system to produce an alarm. You configure a condition to produce an alarm whenever a certain behavior occurs, within specific limits.
Note!
An alarm is generated only if ALL conditions in the Alarm Detection are met.
The Alarm condition limits are reset:
Every time you restart the Platform
Every time you save the alarm configuration
When you resolve the alarm
The Alarm Conditions that you can choose from are:
Host Statistic Value
Pico Instance Statistic Value
System Event
Unreachable Execution Context
Workflow Alarm Value
Workflow Execution Time
Workflow Group Execution Time
Workflow Throughput
Host Statistic Value
The Host Statistic Value condition enables you to setup an Alarm Detection for the various statistic values by host.
