流处理器日志
为有助于监视流处理器队列容量，每个流处理器均添加了新的警告级别日志。若任意单个队列的容量大于等于 70%，则这些警告日志将首先出现在应用程序日志中。对于值流、数据表和流处理器，队列已满后，将拒绝任何向队列中添加条目的尝试。对于持久化属性处理器，其将 (通过创建者超时) 重新尝试向队列中添加条目，重试超时后，若无法添加条目，则该条目会遭到拒绝。遭拒条目会根据上述全新 totalWritesRejected 指标予以计数。
以下为这些日志语句的示例。

应监视每个流条目处理器的应用程序日志，以尽可能减少遭拒条目。
以下为此日志语句的模板：
{ProcessorName} queue #{queue number} is curently {percentage} percent full that is at or above 70.0 percent threshold
以下是可在上述日志语句中代替 {ProcessorName} 的所有流处理器的名称：
• BatchStreamProcessor
• BatchValueStreamProcessor
• ValueStreamProcessor
• DataTableProcessor
• InfluxdbStreamProcessor
• InfluxdbValueStreamProcessor
• PersistentPropertyProcessor
• StreamProcessor
