IRIS, Caché监控指导 - 控制台日志和错误

这里只讨论Caché和IRIS本身产生的错误和警告。用户在维护工作中通常会需要更多的内容， 那些我们在后面的 “系统性能指标”里介绍。另外， 关于集成平台的告警和日志， 也会在后面单独讨论。集成平台，也就是Ensemble Production，是IRIS系统上运行的应用，它的日志，告警，以及指标，测量，是单独的内容。

控制台日志

控制台日志是系统运行状态的日志文件，在IRIS里是messages.log, 在Cache‘里的名字是console.log，默认放在安装目录的mgr子目录。 用户也可以在管理门户的"系统操作>系统日志>控制台日志"里查看。以下是一个实际的例子：
