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.
