This is the project homepage of PerfMon which is a SNMP based performance monitoring tool. PerfMon has the following chracteristics: High performance, it requires little cpu to run, even with more that thousand hosts being polled. No lockups when multiple hosts are unreachable. Elements are placed in a hierarchy of groups for easy access. Easy to use web interface that is completely templated, it is possible to use different templates for each group. PerfMon can search a configurable table and use the index found to poll some variables (e.g. search for a ifDescr with value eth0 and poll ifInOctets and ifOutOctets). Configuration is easy, every instance polled requires only one additional line. New SNMP objects to poll can easily be defined by configuring the MIB to use and the object from the MIB you want to poll (e.g. ciscoEnvMonTemperatureStatusValue from MIB CISCO-ENVMON-MIB). You can add new types of graphs whithout programming. Take a look at the screen captures to get a quick overview of PerfMon.
