xMatters allows me to identify the user responsible for the initiation of an event or a user who acknowledges an event. But the xMatters event log does not appear to identify the user who terminates an event manually. Termination can be done not just by the initiator, but also by other users. A manually-terminated event probably was opened in error, or some new detail about the corresponding incident made notification through xMatters unnecessary. In the worst-case scenario, someone might terminate an event to delay/prevent resolution of an incident. Is there a break in the audit trail, or does this information reside somewhere other than the event log?
