From a Message Broker perspective, target endpoints need note be predefined in your message flow, since they can be retrieved dynamically at runtime. 从MessageBroker的角度看,不需要在消息流中预定义目标端点,因为可以在运行时动态检索这些端点。
This example uses a predefined "ping" Nagios plug-in, which sends Internet Control Message Protocol ( ICMP) echo requests to determine if a host is responsive or not. 这个示例使用了一个预定义的“ping”Nagios插件,它将发送Internet控制信息协议(InternetControlMessageProtocol,ICMP)回显请求以确定主机是否有响应。
Certain predefined situations are triggered when there are faults caused by Web services, such as when message sizes or response times for the Web services exceed the configured thresholds. 当Web服务导致错误时(如Web服务的消息大小或响应时间超过配置的阈值时),将触发特定的预定义境况。
This is beneficial, especially when you need to communicate with an existing Web service or client that needs to communicate using a predefined message format. 这对用户很有帮助,特别是当用户需要与现有Web服务或客户端(它们需要使用预定义的消息格式进行通信)进行通信时更是如此。
The spot initiates to detect temperature according to predefined periodic time. If the temperature measured is higher than the stated threshold, the spot opens receiving module to wait for the enquiring message from host so as to send temperature data. 测温节点根据设定周期启动测温,如果温度超过设定阈值,则打开收发模块,等待主机的轮询信号以便发送温度数据。
By means of registering some predefined events on client application, the mechanism enables the client to send message to log server for statistics. 该跟踪机制通过改造网站客户端,使之能将预定义的用于统计的事件发送到分析日志服务器上。
