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.

VolAlertName, volAlertEnum, and volAlertType variables indicate when to set or clear NMS internal alarms. System-related traps (other than for media), though not used to set or clear alarms, provide important information about the defect source, such as volAudioLevel and volAlertSeverity.
