Abstract: Apparatus and method for detection, triaging and remediation of unreliable message execution in a multi-entity (e.g., multi-tenant) runtime. The described system solves this reliability issues of message handlers in a multi-tenant distributed application runtime by automated metering, detecting, triaging, remediating, and notifying stakeholders, in a proactive way.
