Monitoring Distributed Task Execution Using a Chained Text Messaging System

A system for monitoring tasks processing in a distributed system, comprising:

• a task controller configured to:
• distribute a task as a plurality of subtasks to a plurality of computing devices within the distributed system for execution, wherein a respective computing device executes a subtask, the subtask including a remote method invocation (RMI) object that invokes a callback function;
• monitor execution of the plurality of subtasks using at least one message generated by the RMI object on the respective computing device;
• and
• determine a progress and status information of the task based on the at least one message.

A computer-readable medium, having instructions stored thereon, wherein the instructions cause a computing device to perform operations for monitoring task processing in a distributed system, the operations comprising:

• distributing a task as a plurality of subtasks to a plurality of computing devices within the distributed system for execution, wherein a respective computing device executes a subtask, the subtask including a remote method invocation (RMI) object that invokes a callback function;
• monitoring execution of the plurality of subtasks using at least one message generated by the RMI object on the respective computing device;
• and
• determining a progress and status information of the task based on the at least one message.
