表 1. Expression queue status and statistics
Field 說明
現行佇列狀態
  • Queued Expressions: Number of expressions currently in the queue that are waiting to be run.
  • Running Expressions: Number of expressions currently in the queue that are started, but has not completed.
  • Concurrent Expression Threads: Number of threads on all nodes that are currently running the expressions.
表示式佇列歷程圖形
  • Queued: Number of queued expressions over time. It is displayed as a line in the graph.
  • Running: Number of running expressions over time. It is displayed as a line in the graph.
  • Added: Number of expressions that are added to the queue at a certain point in time. It is displayed as a bar in the graph.
  • Successful: Number of expressions that are run at a certain point in time. It is displayed as a bar in the graph.
  • Failed: Number of expressions that are run with errors at a certain point in time. It is displayed as a bar in the graph. A message with details about the error is displayed in the expression holder attribute.
Select the graph horizon by clicking the links for either All (displays all history since dawn), 24 hours, 1 hour, 5 minutes, or 1 minute.
佇列產量
  • Successful Evaluations: Number of expressions that are run successfully.
  • Failed Evaluations: Number of expressions that are run with errors.
  • Number of Added or Changed Expressions: The sum of all new expressions and all changed expressions.
佇列效率 The lower the numbers for queue efficiency, the fewer the expression container attributes with the Pending Update message.
  • Successful Evaluation Mean Time: The mean time for executing an expression successfully.
  • Average Latency: The average time an expression is in the queue before a thread starts to run the expression, regardless of being successful or failed.
  • Max Latency: The maximum time an expression is in the queue before a thread starts to run the expression, regardless of being successful or failed.
  • Average Queue Time: The average time taken to add, run and complete an expression, regardless of being successful or failed.
  • Max Queue Time: The maximum time taken to add, run and complete an expression, regardless of being successful or failed.
