System Threshold window for setting text-string thresholds

This topic describes the System Threshold window for setting text-string thresholds in IBM® Director.

Introduction

This dialog enables you to define a string threshold for a selected managed system or group.

Fields

Name
Identifies the threshold. This name identifies the threshold when you view a listing of thresholds in the All Available Thresholds window.
Description
Enter additional descriptive information here, for example, list the criteria or the purpose of the threshold. This description is included when you view a listing of thresholds in the All Available Thresholds window. This information can also be included as part of the event text when an event is entered in the event log.
Enabled to generate events
Selecting this box activates the threshold when you save the information. Leave this check box blank if you do not want to activate the threshold.
Generate events on value change
Selecting this box will result in events being generated when the value of the tracked attribute changes. A severity level of Warning is assigned to the event.

All other threshold specification fields except for Minimum Duration are disabled when you select this option because you cannot specify a range of values and because the severity of the event is fixed.

Maximum queued events
Specifies the number of events for this threshold to be held for the server when the server is unavailable. This setting is ignored on agents that do not support event queuing.

The Block queued events option in the Event Filter Builder window allows you to specify whether blocked queued events are included in an event filter.

Minimum Duration
Specifies the length of time these criteria have to be met before an event is triggered.

For example, if you select 5 minutes in this field and specify a string threshold of "offline," the string "offline" must be consistently issued for at least 5 minutes before an event is triggered.

Resend Delay
Specifies the length of time that must transpire after an initial event is triggered before a subsequent event is triggered.

For example, if you select 1 hour in this field and these criteria cause an event to trigger, another hour must elapse before a second event is triggered. The specified criteria have to be met continuously during the interval for the event to trigger when the interval expires.

Threshold strings
Specifies the text string used to generate an event. If more than one string is defined, if any string occurs that matches a defined string, an event is triggered.
String
Specifies the text string used to generate an event. If more than one string is defined, if any string occurs that matches a defined string, an event is triggered.

If the attribute selected has one or more enumerated (predefined) strings, the strings are listed in this pane. You can select a string and change the severity level of the string, but you cannot modify a string or delete a string from the list.

Level
Identifies the severity level of the string threshold.
Add
Select this option to add a string value and severity level to this threshold. This option does not apply to enumerated attribute strings.
Edit
Select a string entry then click this option to edit the entry.

If the attribute has enumerated strings, you can use this option to change the severity level of one or more strings, but you cannot edit the listed string value.

Delete
Select a string entry then click this option to remove the entry as a threshold criterion. This option does not apply to enumerated attribute strings.
Default event type for strings not listed above
Select the severity level that applies to strings generated except those listed. The default severity level is Normal. This option is useful for isolating and responding to the severity of the listed strings.

For Exampled, if you want to isolate a string value to generate an event with a specific severity level, you can use the default severity of Normal in this option to indicate that the occurrence of all other string values associated with this attribute will generate an event with a Normal severity.

This option does not apply to enumerated attribute strings.
