How does snmptt work?
SNMPTT is an SNMP trap handler written in Perl for use with the NET-SNMP/UCD-SNMP snmptrapd program. Received traps are translated into user friendly messages using variable substitution. Output can be to STDOUT, text log file, syslog, NT Event Log, MySQL (Linux/Windows), PostgreSQL, or an ODBC database.

What is Nagios SNMP?
Nagios provides complete monitoring of SNMP (Simple Network Management Protocol). SNMP is an “agentless” method of monitoring network devices and servers, and is often preferable to installing dedicated agents on target machines.
Can Nagios send SNMP traps?
Nagios provides management of SNMP traps – including the ability to read, process, and generate alerts from SNMP traps it receives. Nagios can also send SNMP traps to other management hosts, which allows seamless integration with other Network Management Systems.
What is SNMP trap used for?
An SNMP trap message is an unsolicited message sent from an agent to the the manager. The objective of this message is to allow the remote devices to alert the manager in case an important event happens. In other words, traps don’t need a status request from the master.
What is OID in Nagios?
SNMP (Simple Network Management Protocol) is a network protocol designed for monitoring network-attached devices. It uses OIDs (Object IDentifiers) for defining the information, known as MIBs (Management Information Base), that can be monitored.
What protocol does SNMP use?
User Datagram Protocol (UDP)
Typically, the SNMP protocol is implemented using the User Datagram Protocol (UDP). UDP is a connectionless protocol that works like the Transmission Control Protocol (TCP) but assumes that error-checking and recovery services are not required.
Does Nagios core support SNMP?
Nagios Core is fully capable of monitoring SNMP through both SNMP traps and active polling.
What is the difference between SNMP and SNMP trap?
An SNMP poll is initiated by the server and the router or switch responds to the server. An SNMP trap is initiated by the router or switch when it has information to send (usually some event happened) and does not want to wait for the server to ask for information.
What is SNMP polling and trap?
SNMP protocol works in two different ways: SNMP polls and traps. Polling consists of launching remote queries, either actively or on demand, carrying out operation queries synchronously. Traps, meanwhile, are messages sent by SNMP devices asynchronously, according to changes or events, to configured addresses.
What is hard and soft state in Nagios?
There are two state types in Nagios Core – SOFT states and HARD states. These state types are a crucial part of the monitoring logic, as they are used to determine when event handlers are executed and when notifications are initially sent out.
