Dynamic Cluster Wide Subsystem Engagement Using a Tracing Schema

A computer system comprising:

• a node including a processor-based device executing computer-readable code to provide functionality;
• an application running on the processor-based device and experiencing a plurality of states of a state machine, the application encountering a tracepoint in response to experiencing one of the states;
• and
• a tracepoint interpreting utility running on the processor-based device and configured to:
• receive the tracepoint, wherein the tracepoint includes data describing the tracepoint and metadata describing the state of the processor;
• determine whether the metadata further includes action data that describes one or more actions to be invoked;
• and
• when it is determined that the metadata describes one or more action, invoking the one or more actions.

A method of affecting changes throughout a cluster in a multi-node cluster-based computer system, each node including a processor that executes application, comprising:

• processing an instruction associated with an application at a processor in one of a plurality of nodes in the cluster-based computer system;
• encountering an error as a result of processing the instruction, the error being associated with a tracepoint;
• pausing the processing of the application's instructions while the processor:
• stores state data that describes the state of the processor to a memory buffer, the state data including action data that identifies actions to be invoked throughout the cluster;
• and
• notifies a messaging utility that state data has been buffered;
• and
• in response to the notification:
• accessing via the messaging utility the state data and associated action data;
• determining from the action data the actions to be invoked throughout the cluster;
• and
• invoking the actions throughout the cluster.
