SysOrb can monitor any numerical measurements available through SNMP and this can be used for monitoring network devices like Switches,Routers,printers etc.
SysOrb comes with a number of MIB's pre-installed. These MIB's cover standard parameters such as traffic statistics for routers and switches, and some common printer parameters. You should be able to set up basic monitoring of almost any SNMP enabled router, switch or printer without adding other MIB files.
Should you, however, wish to monitor vendor-specific parameters on your network equipment, you will need to add the relevant MIB files to the ones already in SysOrb. It is easy to ad MIB files to the SysOrb server while it is running and operational.
