Alarms |
This chapter summarizes the Alarm Rules that are specific to the supported platform components.
The chapter contains the following sections:
The hardware common config reader contains a number of alarm rules used by the system to determine the state of various components. Each alarm rule instance is applied to a specific property of a table in the config reader. A single rule can be applied to multiple properties and tables.
An alarm rule takes input from three main sources:
All three of these sources can be modified on a per-object and property basis. You can change user-specifiable values, while the rule programmer specifies which object properties and stored data are used.
You can assign actions to rule states and state transitions through the Sun Management Center console (see chapter 9 and chapter 12 of the Sun Management 3.0 Center Software User's Guide).
This rule is applied to any node that contains an operational status property. It will alarm if the operational state is anything other than OK, Starting or Stopping (all of which are deemed to be normal operational states). The error string incorporates the value of the Additional Information property to provide additional information to the end user.
|
Alarm Severity for each of the following four groups of Operational Status values: |
This rule is applied to any table with an availability property.
|
Alarm Severity for each of the following three groups of Availability values: |
This rule is applied to any non-numeric sensor. It uses the Current Reading in the error message.
This rule is applied to any numeric sensor. It reads the various thresholds presented in the sensor, and generates an alarm if the current value is outside the specified ranges.
|
Numeric Temperature, Voltage and Current Sensors, Tachometers |
|
|
Alarm Severity for Non-Critical, Critical and Fatal thresholds |
This rule generates an alarm when the occupancy of a location changes.
|
Note - You can clear this alarm by acknowledging the alarm in the Sun Management Center console. All other alarms are cleared by a change of state. |
This rule enables you to specify a rate or count for any integer property. If the rate or count exceeds the specified values, an alarm is generated. Apply the rule to all properties that count a number of errors, so that you can generate such alarms as required.
This rule only applies to the Module Status property in the system object. It is primarily used to report module data acquisition problems.
|
An Alarm Severity level can be assigned to each of the Module Status Severity levels of Information, Warning and Error |
This rule applies only to the Indicator Alarm Status property in the Indicator object.
