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.

Search for	Operator	Example
Two or more words in the same topic	`AND` `and` `+` (plus symbol) `&` (ampersand)	`cat AND dog` `"cat food"+milk` `"cat food"&"dog food"`
Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`
Topics that contain one string and do not contain another	`^` (caret)	`cat ^ mouse`
A combination of search types	`( )` parentheses	`cat + (dog \| mouse)` `cat \| dog + (! mouse)`

Determine Reasonable Threshold Settings

You must decide how to define normal behavior for devices in the associated Node Group or Interface Group. You can then set reasonable thresholds for the group and avoid Threshold Incident storms. See Examples of Count-Based Threshold Monitoring and Examples of Time-Based Threshold Monitoring.

Access the NNM iSPI Performance for Metrics Headline report:

Prerequisites:
1. Create a Node Group or Interface Group filter that includes the devices you want to monitor. See Create Groups of Nodes or Interfaces.
2. Export the Node Group or Interface Group filter to NNM iSPI Performance for Metrics.
  
  Tip (NNM iSPI Performance for Metrics only) NNMi automatically synchronizes Interface Group and Node Group configuration changes between NNMi and NNM iSPI Performance. However, in some cases, additional configuration changes that affect Node Group or Interface Group membership might take longer to synchronize. If you do not see one or more nodes in an NNM iSPI Performance report that are visible in NNMi, use the Actions → NNM iSPI Performance → Sync Interface and Node Groups with NNMi option. This option forces NNMi to synchronize the Interface and Node Group information between NNMi and NNM iSPI Performance more quickly than the default time frame.
3. Enable Performance Monitoring for the Node Group or Interface Group. See Node Settings for Monitoring or Interface Settings for Monitoring.
4. Wait a minimum of 24 hours before following the steps below.
In the NNMi console, click Actions → NNM iSPI Performance → Reporting - Report Menu.
Click the link for Headline. The Headline report displays data from the past 24 hours from the time you request the report. So if you run the report at 5.03 p.m., the report includes data since 5.03 p.m. yesterday. Click the Help link in the report if you need information about how to use this report.
Open the Topology Filters panel and restrict your view to the network elements for which you are determining thresholds.
Click Confirm Selection to return to the report.
Open the Time Controls panel and select a start time and interval.
Click Confirm Selection.
The report appears using the filters you specified.
Study the Range & Exceptions graphs to guide your decision about what constitutes reasonable threshold settings. See online help for this report for information about how to read this report.
