SNMP Monitoring with Nagios

摘要

Nagios has been around since 2002 and is considered stable software. It is in use by the likes of American Public Media, JP Morgan Chase and Yahoo, just to name a few. It is an enterprise-level network and systems-monitoring platform. Nagios performs checks of services and hosts using external programs called Nagios plugins.rnSNMP (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. The design is extensible, so vendors can define their own items to be monitored.
