System and Method for a Simple Network Management Protocol Downtime Calculator

A system and method for simple network management protocol downtime calculator includes storing a log comprising a plurality of trap events from corresponding nodes in a subsystem in a network, the plurality of trap events comprising down events and up events, parsing the log to separate down events and up events, pairing down events with corresponding up events, the pairing including matching, for the at least one node in the subsystem, a down event having a severity level with an up event having the corresponding severity level, calculating subsystem downtime, and calculating operational availability of the subsystem. Additional features include identifying overlapping downtimes in the subsystem.
