Items 数据预处理 PREPROCESSING l 5.0版本前，所有预处理操作在Server端处理，5.0版本及以后预 处理操作在Proxy端操作。 l 预处理的相关配置项：StartPreprocessors= 默认为3 l 4.4 版本后，当预处理失败后，可以选择输出默认值，4.4版本前 需要保证输入值正常，否则处理失败后监控项会变成不支持 问答时间 questions 加入技术交流群

configurations. A StartPreprocessors configuration parameter has been added to Zabbix server configuration. As a preprocessing manager process is introduced in this version, the ’StartPreprocessors’ parameter that a non-zero value is required for internal, aggregated and calculated items to work. StartPreprocessors no 1-1000 3 Number of pre-forked instances of preprocessing workers1. The preprocessing Zabbix server configuration file allows users to set count of preprocessing worker processes. StartPreprocessors configuration parameter should be used to set number of pre-forked instances of preprocessing

that a non-zero value is required for internal, aggregated and calculated items to work. StartPreprocessors no 1-1000 3 Number of pre-forked instances of preprocessing workers1.

server configuration file allows users to set the count of preprocessing worker threads. The StartPreprocessors config- uration parameter should be used to set the number of pre-started instances of preprocessing hosts (including IPMI and Java). StartPollers The number of pre-forked instances of pollers. StartPreprocessors The number of pre-started instances of preprocessing workers. StartProxyPollers The number StartPollers The number of pre-forked instances of pollers1. Default: 5
Range: 0-1000 StartPreprocessors The number of pre-started instances of preprocessing workers1. Default: 3
