xcmHrDevAlertV2Event — Multiple manufacturers; see the original MIB MIB copies (LibreNMS/Observium Community)
This trap is sent whenever a device alert row transitions to 'active' row status or (optionally) transitions to 'notInService' row status in 'xcmHrDevAlertTable'. This trap is sent when requested by a prior subscription. Note: The variable-bindings of this trap have been chosen to specify a complete device alert event while keeping trap messages reasonably concise (generally a few hundred octets at most). This notification has the following special semantics: o The device's 'hrDeviceIndex' field value SHALL be appended to this trap object ID, as a BER binary OID suffix. This trap OID qualifier allows device management/monitoring applications to limit the alerts they receive to ones generated by devices of interest. Systems MAY add other variable-bindings from any MIB.
