背景信息
我最近刚开始在生产ColdFusion 10服务器上遇到这些错误:
Service Temporary Unavailable!
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Jakarta/ISAPI/isapi_redirector/1.2.32 ()
在谷歌呆了几个小时后,我在adobe论坛上看到了这个帖子:

这篇文章中有很多信息,但我主要关注两个方面。
-
获取线程/会话/内存度量的当前使用情况。
-
使用度量信息调整ColdFusion IIS连接器配置
我的目标是完成这篇博文:

此报告的错误中引用了日志:

问题
我目前被困在#1;获取线程/会话/内存度量的当前使用情况。
我检查了:CFadmin>调试&日志记录>调试输出设置>启用度量记录。
ColdFusion 10 metrics.log:
"Information","scheduler-1","07/20/14","15:12:24",,"Max threads: null Current thread count: null Current thread busy: null Max processing time: null Request count: null Error count: null Bytes received: null Bytes sent: null Free memory: 1055964040 Total memory: 1570766848 Active Sessions: 679"

在ColdFusion 11开发服务器上,我打开了EnableMetricsLogging,只是想看看它报告了什么。该文件的metrics.log如下所示:
"Information","scheduler-1","07/20/14","15:20:59",,"Max threads: null Current thread count: null Current thread busy: null Max processing time: null Request count: null Error count: null Bytes received: null Bytes sent: null Free memory: 589971080 Total memory: 1320157184 Active Sessions: 40"

"Information","scheduler-2","07/20/14","15:22:59",,"Max threads: null Current thread count: null Current thread busy: null Max processing time: null Request count: null Error count: null Bytes received: null Bytes sent: null Free memory: 907572096 Total memory: 1431830528 Active Sessions: 40"
问题是,几乎所有的信息都返回为“空”。
ColdFusion 10环境:
Windows Server 2008 R2,
ColdFusion 10标准64位,
Java 7u60
ColdFusion 11环境:
Windows Server 2012 R2,
ColdFusion 11标准64位,
Java 7u65
附加说明
这在coldfusion 10上的coldfusion-error.log中找到(但不在CF 11中):
java.lang.NullPointerException
at coldfusion.server.jrun4.metrics.SimpleLoadMetric.run(SimpleLoadMetric.java:157)
at coldfusion.scheduling.ThreadPool.run(ThreadPool.java:211)
at coldfusion.scheduling.WorkerThread.run(WorkerThread.java:71)
问题
是否有人知道如何使用EnableMetricsLogging来实际报告使用的线程?
在第一个链接中,“carl type3”发布了他的metrics.log文件的示例,其中包含了我想要获取的所有信息。
