The program allows you to monitor OID and MIB values on switches via the SNMP protocol.
SNMP (Simple Network Management Protocol) – a widespread protocol, which functions include managing network devices and obtaining information on their performance in particular. As a rule, all modern manageable network devices (workstations, laptops, switches, printers, routers, modems, web cams, etc.) have the so-called Management Information Base (MIB). That base contains a lot of useful information on the state of the device: output counters, active processes, network traffic values on the interfaces, etc. In some devices, the total number of different records in such bases can reach tens of thousands. Each record in the base is accompanied by a unique identifier OID (object identifier). Having OID of the record storing the parameter of interest, you can configure the application to monitor it. The application will connect to the device over the SNMP protocol, then obtain the parameter value over OID and then compare it with the specified value. If the parameter value doesn't match the specified one, the application will alert of that.
More information on configuring SNMP and obtaining data from MIB can be read on these resources:
