      Fields 
      Modifier and Type Field Description
      static io.prometheus.client.Gauge CURRENTLY_INSTANTIATED_TASKS
      Count the number of tasks created by the distributor and not yet completed The tasks maybe in the queue or waiting to be enqueued
      static io.prometheus.client.Histogram PROCESS_WORKFLOW_STEP_EXECUTION_DURATION_HISTOGRAM
      ProcessWorkflow step execution duration form ProcessEngine point of view
      static io.prometheus.client.Gauge REGISTERED_WORKERS
      Count the number of registered workers If we know that we have 2 workers, but metrics says 1 worker => this means that we have to analyse why we have only 1 instead of 2
      static io.prometheus.client.Histogram WORKER_TASKS_EXECUTION_DURATION_HISTOGRAM
      Worker task execution duration From call of worker until receiving the response.
      static io.prometheus.client.Histogram WORKER_TASKS_IDLE_DURATION_IN_QUEUE
      Worker task waiting in the queue From task creation, until dequeue by a given thread
      static io.prometheus.client.Gauge WORKER_TASKS_IN_QUEUE
      Count the number of worker task in the queue If the queue is empty, means there no more operation.

      • WORKER_TASKS_IN_QUEUE

        public static final io.prometheus.client.Gauge WORKER_TASKS_IN_QUEUE
        Count the number of worker task in the queue If the queue is empty, means there no more operation. => if per month for example we have empty queue, means that we can reduce the number of workers If the queue is full, means that worker cant consume all tasks => perhaps, we have to add more workers
