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`

Investigate and Diagnose Problems

NNMi offers several ways for you to investigate and diagnose network problems.

The Causal Engine keeps track of changes in your network, and alerts you to the root cause of problems and potential problems. See Interpret Root Cause Incidents for more information.
Start by accessing the available information for the Source Object and Source Node for the incident. To access all known information about the Source Object, access the incident's Source Object form . NNMi monitors the following object types:
- Node (and Node Sensors: for example buffers. CPU, disks, memory)
- Chassis (and Physical Sensors: for example backplane, fan, power, temperature, voltage)
- Card
- Interface
- IP Address
- SNMP Agent
- Node Group
- Card Redundancy Group
- Router Redundancy Group
Select an incident. Then, select Actions → Source Object. NNMi displays the form for the object associated with the incident.

A wealth of information about that object is available.
- The object's form is displayed in the top half of the display window. Use the Conclusions tab to display a history of any problems that led to the object's current Status.
- The Analysis Pane is displayed in the bottom half of the display window. It provides a quick summary of available information. For example, the Details tab also lists the available Conclusions.

To explore the information about the object, use the browse buttons:

to display a list of all available tabs. Select any tab name from the list to display that tab.
to display the next subset of tabs (depending on the current width of your NNMi window).

You will find the object's State, Status (No Status, Normal, Warning, Minor, Major, Critical, Disabled, or Unknown), Conclusions, and any related incidents.

If the Source Object is not a node, you can access the form for the node associated with the object by selecting Open using the Lookup icon from the Hosted on Node or Managed By attribute.

Once again, information about the State, Status, and Conclusions can assist yow with identifying the problem.
Use the Actions menu to gather the latest information about multiple aspects of a node (rather than waiting for the next regularly scheduled collection time).
The Actions menu also provides an easy way to use troubleshooting commands to diagnose node connectivity and access problems:
You can also access Line Graphs from the Actions menu to investigate a problem. See Monitor with Graphs for more information.
Use Tools → MIB Browser or select Actions → MIB Information → MIB Browser from a Node or Incident form to view MIB Information for a node. See Run SNMP Walk Commands (MIB Browser) for more information.
If you have NNMi role permits, you can use Actions → Open Incident Configuration to access more information about the incident including its Description, which includes reasons why the incident is generated.
You can also right-click any object in a table or map view to access the items available within the Actions menu.
Use the Tools menu to find a problem node. You can also use the Tools menu to verify that NNMi, itself, is running properly. This includes checking the status of NNMi processes and services:
