  collect sends JFR data to the OAP server

  message AsyncProfilerData

  AsyncProfiler.proto:36

  • optional AsyncProfilerMetaData metaData = 1

    metaData of the AsyncProfiler task and its result data, only sent in the first request.

  • oneof result

    • string errorMessage = 2

    • bytes content = 3

      JFR binary content

  message AsyncProfilerCollectionResponse

  • AsyncProfilingStatus type = 1

• rpc getAsyncProfilerTaskCommands (AsyncProfilerTaskCommandQuery, v3.Commands)

  AsyncProfiler.proto:33

  getAsyncProfilerTaskCommands sends query to the OAP server for all AsyncProfiler tasks to be executed for the given Java Agent instance

  message AsyncProfilerTaskCommandQuery

  • string service = 1

    service name of the Java process

  • string serviceInstance = 2

  • int64 lastCommandTime = 3

    lastCommandTime is the timestamp of the last AsyncProfiler task received

• string service = 1

• string serviceInstance = 2

• string taskId = 3

  async-profiler task id

• AsyncProfilingStatus type = 4

  AsyncProfilerCollectType indicates the overall status of the AsyncProfiler task, i.e. success or failure

• int32 contentSize = 5

  if type is success then it will be the size of the JFR file, otherwise it will be 0

Used in: AsyncProfilerCollectionResponse, AsyncProfilerMetaData

• PROFILING_SUCCESS = 0

  PROFILING_SUCCESS indicates the Java Agent has finished the execution

• EXECUTION_TASK_ERROR = 1

  EXECUTION_TASK_ERROR indicates a potential execution error caused by the Java Agent, such as an error in the task parameters that were sent.

• TERMINATED_BY_OVERSIZE = 2
