This DisplayString, accessible only via notification (accessible-for-notify), carries the textual description of an event detected by the CODIMA Express, such as an activity failure, threshold breach, or Expert System discovery. An admin reads this field inside the SNMP trap to understand, in plain text, exactly what condition triggered the alert without needing to decode separate numeric alarm fields. For example, alarmMessage might read something like "Node stopped transmitting" when a monitored device's activity abruptly ceases, immediately telling the admin what happened.
