PHP classes for monitoring various devices via SNMP, supporting v1 and v2c.
This code could be the building block for the poller in a monitoring suite, for example.
Currently tested on HP ProCurve 1920-48G and Synology RS815+, but it's designed to be easily ported to any other SNMP enabled device.
Requires php5-snmp and snmp-mibs-downloader packages to be installed.
