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`

About the State Poller

The State Poller Service monitors each discovered interface, address, card, and SNMP agent that is designated to be actively monitored in your management domain. State Poller can also be configured to provide Node Sensor, Physical Sensor, and Router Redundancy Group monitoring.

State Poller gathers information in the following area and updates the State field on each object's form:

Verifies that each monitored IP Address is responding to ICMP ping.
Verifies that each monitored SNMP Agent is responding to SNMP queries.
Issues SNMP queries for the following:
- Each monitored interface, requesting the current value for MIB-II ifAdminStatus and ifOperStatus. (ifAdminStatus is set by the device administrator. ifOperStatus indicates the operational status of interface health.)
- Router Redundancy Groups.
- Node Sensor data.
- Physical Sensor data.
By default, State Poller monitors interfaces connected to another known interface through a Layer 2 Connection.
You can extend monitoring to include the following:
- Unconnected interfaces
- Interfaces that have an IP address (for example a router interface that services mobile laptop machines)
- (NNM iSPI Performance for Metrics). The State Poller also collects performance data and monitors thresholds. See Purchase Network Node Manager i Smart Plug-ins and More.

The State Poller stores the State changes resulting from the queries in the NNMi database and notifies the Causal Engine of any changes. When notifying the Causal Engine of any changes, the State Poller sends only those State values that have changed.

Tip To force the State Poller to send the Causal Engine all of the State information it can collect regardless of changes, use Actions → Status Poll or the nnmstatuspoll.ovpl command.

The Causal Engine gathers additional information about the overall health of each interface and SNMP agent. Using the State information collected from the State Poller as well as this additional information the Causal Engine calculates the Status of each node, interface, and SNMP agent.

Note Any time the State Poller sends updated State values for a selected object, the Causal Engine reanalyzes Status, Conclusions, and Incidents, and updates this information if needed.

See The NNMi Causal Engine and Monitoring for more information.
