Monitor your network infrastructure with SNMP

Clear View


SNMP lets you collect a large volume of data that can help you with your evaluation and thus support troubleshooting. The protocol and the queries are easy on resources, so you could assign other tasks to your Raspberry Pi, if necessary.

That said, plain vanilla SNMP queries are not to the liking of administrators who prefer monitoring in real time with visualization. If this sounds like you, you might prefer to go for MRTG, Cacti, or legacy network monitoring tools such as Nagios, Icinga, Zabbix, or Munin.
