Using SNMP with InterSystems IRIS
SNMP defines a client-server relationship where the client (a network management application) connects to a server program (called the SNMP agent) which executes on a remote network device or a computer system. The client requests and receives information from that agent. There are four basic types of SNMP messages:
-
GET – fetch the data for a specific managed object
-
GETNEXT – get data for the next managed object in a hierarchical tree, allowing system managers to walk through all the data for a device
-
SET – set the value for a specific managed object
-
TRAP – an asynchronous alert sent by the managed device or system
The SNMP MIB (Management Information Base) contains definitions of the managed objects. Each device publishes a file, also referred to as its MIB, which defines which portion of the standard MIB it supports, along with any custom definitions of managed objects. For InterSystems IRIS, this is the ISC-IRIS.mib file, located in the install-dir\SNMP directory.
