LoadRunner监控Apache

2010-04-30  刘小袁 

一、Apache上的设置

打开<Apache Installation>\conf\httpd.conf,进行如下修改:

1  设置允许查看Apache运行状态的主机

#

# Allow server status reports, with the URL of http://servername/server-status

# Change the ".your-domain.com" to match your domain to enable.

#

#取消一下代码前面的注释符号“#”,并且设置Order(顺序)为允许优先

<Location /server-status>

    SetHandler                              server-status

    Order                                      allow,deny

    Deny from                                    nothing

    Allow from                                  all

</Location>

这样改变以后重新启动Apache在浏览器中输入http://servername/server-status就可以看到Apache运行时的信息,而输入http://servername/server-status?auto就会看到如下信息:

Total Accesses: 124

Total kBytes: 444

CPULoad: 3.32432

Uptime: 37

ReqPerSec: 3.35135

BytesPerSec: 12288

BytesPerReq: 3666.58

BusyWorkers: 1

IdleWorkers: 7

Scoreboard: ____W___.........................

看到这样的信息就表示修改成功,这样就可以使用LoadRunner监视Apache了。

以下两步跟使用LoadRunner监视Apache无关,可以跳过不看。

2  改变Apache的设置,打开详细状态开关;

#

# ExtendedStatus controls whether Apache will generate "full" status

# information (ExtendedStatus On) or just basic information (ExtendedStatus

# Off) when the "server-status" handler is called. The default is Off.

#

#取消了下面一行前面的注释符号“#

ExtendedStatus On

3  有用的设置,查看各模块信息

#

# Allow remote server configuration reports, with the URL of

#  http://servername/server-info (requires that mod_info.c be loaded).

# Change the ".example.com" to match your domain to enable.

#

#取消一下代码前面的注释符号“#”,并且设置Order(顺序)为允许优先

<Location /server-info>

    SetHandler                              server-info

    Order                                       allow,deny

    Deny from                              nothing

    Allow from                                   all

</Location>

二、LoadRunner上的设置

经过以上第一项设置以后就可以使用LoadRunner监控Apache的运行情况了,在LoadRunner可用的监视器中双击Web Server Resource Graphs下的Apache节点,然后在右边对应的窗口中添加Apache所在主机的IP地址,并且加入计数器后单击OK,这样就可以在LoadRunner中实时显示Apache的运行状态信息了。

注意:您可能收到如下消息【Monitor name :Apache. Parsing error, cannot find token: BusyServers. Measurement: BusyServers|192.168.0.186. Hints: 1) Such a measurement does not exist, or the html page may be different from the supported one. 2) Try to replace the Apache.cfg with appropriate Apache_<version>.cfg file in <Installation>\dat\monitors and rerun the application (entry point: CApacheMeasurement::NewData).       [MsgId: MMSG-47479]】,这是由于要监视Apache的版本提供的计数器与LoadRunner默认的计数器不一致导致的。此时建议先关闭Controller,打开<Installation>\dat\monitors下的apache.cfg文件(其它文件名类似Apache_<version>.cfg的是Apache监视配置的备份,只有apache.cfg是生效的):

1  修改Counter0=IdleServersCounter0=IdleWorkers,同时修改注释信息Label0=#Idle Servers (Apache)Label0=#Idle Workers (Apache),描述信息也建议修改;

2  修改Counter4=BusyServersCounter4=BusyWorkers,同时修改注释信息Label4=#Busy Servers (Apache)Label4=#Busy Workers (Apache) ,描述信息也建议修改。

然后保存并关闭该文件,重新打开Controller并添加计数器,这样监视就正常了。
