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)`

Node Form: Node Sensors Tab

[This is the Context-Sensitive Help topic for the Node form, Node Sensors tab.]

The Node Form provides details about the selected node.

For information about each tab: See Also

The Node Form: Node Sensors tab displays information about node fault and performance metrics:

Management Address ICMP Response Time

Threshold based on elapsed time (in milliseconds) for receiving a node's reply to an Internet Control Message Protocol (ICMP) echo request. The address queried is the node's Management Address attribute value. See the node's Node form, Basic Attributes section for the currently configured address.
(NNM iSPI Performance for Metrics) If the Network Node Manager iSPI Performance for Metrics Software is installed and configured within your environment, the NNMi administrator can configure threshold for the following performance metrics (click here for more information):
- Buffer Failure Rate
  
  Threshold based on the percentage of a node's buffer failures compared to the total number of attempts to create new buffers. These failures are caused by insufficient memory when the device tried to create new buffers.
- Buffer Miss Rate
  
  Threshold based on the percentage of a Node's buffer misses compared to the total attempts at buffer access. Crossing this threshold indicates the number of available buffers are dropping below a minimum level required for successful operation.
- Buffer Utilization
  
  Threshold based on the percentage of a Node's buffers that are currently in use, compared to the total number of available buffers. Nodes have multiple buffers and potentially multiple buffer types (various sizes and manufacturers). This threshold provides results for each buffer type that the Node's SNMP agent is capable of detecting. Therefore, the Node Sensor form might show multiple Buffer Utilization result entries for each polling cycle (one for each group of buffers comprised of a specific buffer type).
- CPU 5Sec Utilization
  
  Threshold based on the percentage of a node's CPU usage compared to the total amount of available CPU capacity. This percentage is the average CPU utilization over the prior 5-seconds.
- CPU 1Min Utilization
  
  Threshold based on the percentage of a node's CPU usage compared to the total amount of available CPU capacity. This percentage is the average CPU utilization over the prior 1-minute.
- CPU 5Min Utilization
  
  Threshold based on the percentage of a node's CPU usage compared to the total amount of available CPU capacity. This percentage is the average CPU utilization over the prior 5-minutes.
- Disk Space Utilization
  
  Threshold based on the percentage of a node's disk space usage compared to the total amount of available disk space.
- Memory Utilization
  
  Threshold based on the percentage of a node's memory usage compared to the total amount of available memory.

Tip See Node Sensor Form for more details about the node sensor attributes that appear in this view's column headings. Node Sensors are displayed in three views: Node Sensors View, Non-Normal Node Sensors View, and Unmanaged Node Sensors View.

Node Sensors Table
Attribute	Description
Node Sensors	Table view of the fault and performance metrics associated with the current node. You can use this table to determine the Status, Name, and Type for each Node Sensor metric associated with the selected node. Double-click the row representing a Node Sensor. The Node Sensor Form displays all details about the selected Node Sensor. Note The NNMi administrator can set Node Sensor thresholds. For more information, see Node Form: Node Sensors Tab, Chassis Form: Node Sensors Tab, and Card Form: Node Sensors Tab.
