MIB variables

SNMP V2 MIB variables, with definitions, are listed in the “EncoderTraps_v2.mib” file or a similar *.mib file located on the Volicon Media Intelligence service server in the “Program Files\Volicon\docs” (Commented [CH1]: Is this up-to-date?) directory. The MIB file should be used in addition to the “MIB variables” table below.

The Volicon Media Intelligence service can send SNMP V2 trap messages both for media-related alerts that create fault clips and for system critical events that do not generate clips.
