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)`

Best Practices Tour for the Troubleshooting Workspace

This Best Practices Tour describes how to use the Troubleshooting workspace to troubleshoot network problems.

Tip The Troubleshooting workspace provides access to the same maps as the Actions → Maps submenu.

Use the maps in the Troubleshooting workspace to see the location of a node, its connections (communication channels) to other devices, and each node’s Status color (calculated by NNMi based on all available data). Status values are listed in table views, as well as on maps. Possible Status values include:

Status	Map Symbol Background Color	Table Column Symbol
No Status		none
Normal
Warning
Minor
Major
Critical
Disabled
Unknown

See Status Color for Objects and Status Color for Aggregator Objects (NNMi Advanced) for more information about Status colors and values.

NNMi uses SNMP and ICMP Polling to gather information about the health of each device in your network environment.

Maps are a quick way to determine which nodes have a Status that is not Normal (green). Maps are valuable tools that help you determine the scope of a problem. For example, a map can indicate whether a problem affects an entire site or only a small subset of devices. The map view you select depends on the types of information you want to view.

The Layer 2 Neighbor View shows a graphical representation of the selected device and any connections with other devices within a specified number of hops (other devices) from the selected device. The map also shows the health of those devices. Layer 2 Connections traverse switches and switch-routers.

The Layer 3 Neighbor View is a graphical representation of the devices in subnets to which the selected node belongs, and the health of the routers in those subnets. The connections in this map traverse routers and switch-routers.

The Node Group Map displays the group of nodes, if any, to which the selected node belongs. Your NNMi administrator can configure Node Groups to group nodes together according to selected criteria, for example by location, importance, or device type.

A Path View map displays the flow of network traffic between two devices, rather than all of the available connections. Path View calculates the route of data flow between two nodes, and provides a map of that information. The end nodes can be Nodes or Routers.

To access the form for any object on the map, double-click the object of interest.

Tip See also the nnmtopoquery.ovpl Reference Page. Use this command-line tool to list all connected neighbor interfaces for a specified node.
