Simple Network Management Protocol (SNMP) is an internet-standard protocol for managing devices on IP networks. SNMP consists of a set of standards for network management, including an application layer protocol, database schema, and set of data objects. Typical devices that support SNMP are routers, switches, servers, workstations, and printers.
SNMP agents expose management data in the form of variables that describe the system configuration. This protocol allows you to modify and apply a new configuration through remote modification of these variables. The variables are organized in tree-structures which are described by Management Information Bases (MIBs). A MIB is a virtual database that is used for managing the entities in a communications network. Each entry in the database is addressed through an object identifier (OID). Each OID identifies a variable that can be read or set using SNMP.
The SNMP Data Monitoring (snmpcollector) probe allows you to monitor network-attached devices for conditions that require administrative attention.
