A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Configure Time-Based Threshold Monitoring for Node Groups

Time-Based Threshold Settings enable you to determine whether a threshold is reached for a particular duration of time (for example, the CPU utilization for a node is above 90 percent for 20 out of 30 minutes).

To establish time-based threshold monitoring behavior for nodes:

Prerequisite. Before setting thresholds, analyze performance data over time to determine wise threshold settings for each Node Group.
- Determine Reasonable Threshold Settings.
- Examples of Time-Based Threshold Monitoring.
Navigate to the Node Settings form.
1. From the workspace navigation panel, select the Configuration workspace.
2. Expand the Monitoring folder.
3. Select Monitoring Configuration.
4. Navigate to the Node Settings tab.
5. Do one of the following:
  - To create an Node Settings definition, click the New icon.
  - To edit an Node Settings definition, select a row and click the Open icon.
In the Node Settings form, navigate to the Threshold Settings tab.
Do one of the following:
- To create a threshold definition, click the New icon and select Time-Based Threshold Settings.
- To edit a threshold definition, select a row and click the Open icon.
- To delete a threshold definition, select a row and click the Delete icon.
Select the Monitored Attribute you want to monitor and establish the threshold values for that attribute.

When you configure thresholds using this technique, NNMi uses the assigned Node Group as a filter (only monitoring the threshold for nodes belonging to the specified Node Group).
Click Save and Close to return to the Node Settings form.
Click Save and Close to return to the Monitoring Configuration form.
Click Save and Close. NNMi applies your changes during the next regularly scheduled monitoring cycle.

Note Threshold Incidents are disabled by default within NNMi to prevent Incident storms. If you are ready to generate Threshold Incidents, see Generate Performance Threshold Incidents (NNM iSPI Performance for Metrics). See also Custom Incident Attributes Provided by NNMi (Information for Administrators) for a description of the special custom incident attributes available in Threshold Incidents.

Basic Time-Based Threshold Settings
Attribute	Description
Monitored Attribute	In the Monitored Attribute drop-down list, select the attribute for which you want to establish a threshold configuration. Tip Some of the choices in the Monitored Attribute selection list do not apply in this context. See the tables in About Threshold Settings Provided by NNMi for information about which Monitored Attributes are available for Node Groups.
A High Threshold situation occurs when: The Monitored Attribute is greater than the High Value for at least the time specified in High Duration within the High Duration Window. When these criteria are met, NNMi does the following: Updates the Threshold's state value to High for the appropriate Interface. Generates the related incident (if one is Enabled ). If an incident is generated, NNMi closes that incident when the Threshold criteria are no longer met.
High Value	The value that above which becomes a threshold situation. Use one of the following: Designate a percentage between 0.00 and 100.00. For special situations, the following values can be used: 0.000000000000001 (or 1E-15 in Scientific Notation) for the smallest value greater than zero. 99.99999999999999 for the highest value less than one hundred. Designate any appropriate integer value (for example, a Management Address ICMP Response Time of 0 or greater milliseconds ). The High Value must be greater than or equal to the designated Low Value. If you use the highest possible value, the threshold is disabled because it cannot be crossed.
High Value Rearm	The High Value Rearm designates the lower boundary of the High Threshold range of values. After entering a High threshold situation, when a returned value is below the specified High Value Rearm, the following happens (for Time-Based Thresholds): The current polling interval does not contribute toward High Duration. The criteria for High Duration and High Duration Window determine when the High Threshold situation ends. Note The High Value Rearm must be less than or equal to the High Value and greater than or equal to the Low Value Rearm.
High Duration	Designate the minimum time within which the value must remain in the High range before the threshold state changes to High and (optionally) an incident is generated. The High Duration should be equal to or greater than which ever currently configured Fault Polling Interval or Performance Polling Interval setting is influencing the Monitored Attribute you chose, because that is how often NNMi provides a data point. See the tables in About Threshold Settings Provided by NNMi for details. See the following topics for instructions about finding the current polling interval setting: Default Settings for Monitoring Interface Settings for Monitoring Node Settings for Monitoring Tip Setting both the High Duration and High Duration Window to zero disables the High threshold.
High Duration Window	Designate the window of time within which the High Duration criteria must be met. The value must be greater than 0 (zero) and can be the same as or greater than the High Duration value. NNMi uses a sliding window, meaning that each time the High Window Duration is reached, NNMi drops the oldest polling interval and adds the most recent. Tip Setting both the High Duration and High Duration Window to zero disables the High threshold.
A Low Threshold situation occurs when: The Monitored Attribute is lower than the Low Value for at least the time specified in Low Duration within the Low Duration Window. When these criteria are met, NNMi does the following: Updates the Threshold's state value to Low for the appropriate Interface. Generates the related incident (if one is Enabled ). If an incident is generated, NNMi closes that incident when the Threshold criteria are no longer met.
Low Value	The value that below which becomes a threshold situation. Use one of the following: Designate a percentage between 0.00 and 100.00. For special situations, the following values can be used: 0.000000000000001 (or 1E-15 in Scientific Notation) for the smallest value greater than zero. 99.99999999999999 for the highest value less than one hundred. Designate any appropriate integer value (for example, a Management Address ICMP Response Time of 0 or greater milliseconds ). The Low Value must be less than or equal to the designated High Value. If you use the minimum possible value, the Low threshold is disabled because it cannot be crossed.
Low Value Rearm	The Low Value Rearm designates the upper boundary of the Low Threshold range of values. After entering a Low threshold situation, when a returned value is above the specified Low Value Rearm, the following happens (for Time-Based Thresholds): The current polling interval does not contribute toward Low Duration. The criteria for Low Duration and Low Duration Window determine when Low Threshold ends. Note The Low Value Rearm must be greater than or equal to the Low Value and less than or equal to the High Value Rearm.
Low Duration	Designate the minimum time within which the value must remain in the Low range before the threshold state changes to Low and (optionally) an incident is generated. The Low Duration should be equal to or greater than which ever currently configured Fault Polling Interval or Performance Polling Interval setting is influencing the Monitored Attribute you chose, because that is how often NNMi provides a data point. See the tables in About Threshold Settings Provided by NNMi for details. See the following topics for instructions about finding the current polling interval setting: Default Settings for Monitoring Interface Settings for Monitoring Node Settings for Monitoring Tip Setting both the Low Duration and Low Duration Window to zero disables the Low threshold.
Low Duration Window	Designate the window of time within which the Low Duration criteria must be met. The value must be greater than 0 (zero) and can be the same as or greater than the Low Duration value. NNMi uses a sliding window, meaning that each time the Low Window Duration is reached, NNMi drops the oldest polling interval and adds the most recent. Tip Setting both the Low Duration and Low Duration Window to zero disables the Low threshold.
