ColdFusion 10/11度量记录问题

Question

背景信息

我最近刚开始在一个生产ColdFusion 10服务器上获取这些错误：

    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 ()

在与google相处了几个小时之后，我在adobe论坛上看到了一条帖子：

https://forums.adobe.com/thread/1016323?start=0&tstart=0

在这个帖子中有很多信息，但是我集中在两个方面。

1. 获取线程/会话/内存度量的当前使用情况。
2. 使用度量信息优化ColdFusion IIS配置

我的目标是写完这篇博文：http://blogs.coldfusion.com/post.cfm/tuning-coldfusion-10-iis-connector-configuration

这篇博文是在这个报告的bug中引用的：https://bugbase.adobe.com/index.cfm?event=bug&id=3318104

问题

目前，我仍然停留在#1；获取当前线程/会话/内存度量的使用情况。

我检查了: CFadmin >调试和日志记录>调试输出设置>启用度量日志记录。

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"
    "Information","scheduler-1","07/20/14","15:13:24",,"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: 1136605536 Total memory: 1572864000 Active Sessions: 674"
    "Information","scheduler-1","07/20/14","15:14:24",,"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: 939095720 Total memory: 1572339712 Active Sessions: 673"

在一个ColdFusion 11开发服务器上，我打开了，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","15:21:59",,"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: 583831160 Total memory: 1320157184 Active Sessions: 41"
    "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，几乎所有的信息都以"null“的形式返回。

ColdFusion 10环境: Windows 2008 R2，ColdFusion 10标准64位，Java7u60

ColdFusion 11环境: Windows 2012 R2，ColdFusion 11标准64位，Java7u65

附加说明

这可以在ColdFusion 10上的ColdFusionError.log中找到(但在CF 11中不是这样)：

    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

有人知道如何让Enable日志记录实际报告使用的线程吗？

在第一个链接中，"carl type3“发布了他的metrics.log文件的示例，其中包含了我想要得到的所有信息。

CF管理度量设置

​

​

ColdFusion 10 workers.properties：

    worker.list=cfusion

    worker.cfusion.type=ajp13
    worker.cfusion.host=localhost
    worker.cfusion.port=8012
    worker.cfusion.max_reuse_connections=250
    worker.cfusion.connection_pool_size=500
    worker.cfusion.connection_pool_timeout=60

ColdFusion 10 server.xml连接器：

<Connector port="8012" protocol="AJP/1.3" redirectPort="8445" tomcatAuthentication="false" maxThreads="500" connectionTimeout ="60000" />

Answer 1

在cfusion中需要设置的正确端口可以在server.xml中找到。

在大多数以IIS作为前端with服务器的设置中，它是8012，因此需要将CF管理中的此设置更改为此值。重新启动coldfusion，您将最终看到cfstat以及度量日志中的一些值。

Answer 2

若要启用度量日志记录，请转到“调试& Logging>Debug输出设置”，然后更新下面突出显示的值。

"Max线程“在日志中显示空值，这进一步推断没有启用度量日志。使用当前线程计数作为connection_pool_size的输入，然后设置max_reuse_connections。您还需要按照connectionTimeout中的建议，在server.xml中添加server.xml和maxThreads。这也适用于CF10。
