ColdFusion 10/11指标记录问题

Question

背景资料

我刚刚开始使用生产ColdFusion 10服务器来解决这些错误：

    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google上花了几个小时后，我在adobe论坛上遇到了这个帖子：

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

这个帖子中有很多信息，但我关注的是两个方面。

1. 获取线程/会话/内存指标的当前用法。

2. 使用指标信息调整ColdFusion IIS连接器配置

我的目标是完成这篇博文： http://blogs.coldfusion.com/post.cfm/tuning-coldfusion-10-iis-connector-configuration

此报告错误中引用了博客文章： https://bugbase.adobe.com/index.cfm?event=bug&id=3318104

问题

我目前停留在＃1;获取线程/会话/内存指标的当前使用情况。

我查了一下：CFadmin＆gt;调试＆amp;记录＆gt;调试输出设置＆gt;启用度量标准记录。

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ColdFusion 11开发服务器上，我打开了启用度量标准，只是为了查看报告的内容。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会以“null”的形式返回。

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

这可以在ColdFusion 10上的coldfusion-error.log中找到（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

有谁知道如何让Enable Metrics Logging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文件样本，它包含了我想要的所有信息。

CF管理指标设置



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

要启用指标记录，请转到调试＆amp;记录＆gt;调试输出设置，然后更新下面突出显示的值。

＆＃34;最大线程＆＃34;在日志中显示空值，进一步推断未启用度量标准日志。使用Current Thread Count作为connection_pool_size的输入，然后设置max_reuse_connections。您还需要在http://blogs.coldfusion.com/post.cfm/coldfusion-11-iis-connector-tuning中建议的server.xml中添加connectionTimeout和maxThreads。这也适用于CF10。

Answer 2

您需要在CF Admin中设置的正确端口可以在cfusion的server.xml中找到。

在大多数使用IIS作为前端网络服务器的设置中它是8012，因此您需要将CF管理中的此设置更改为此值。 重新启动coldfusion，你应该最终看到cfstat以及指标日志中的一些值。
