配置对IBM Http Server的实时监控

文件：{HTTPServerInstallPath}/conf/ httpd.conf
找到以下段落，去掉前面的“#”号即可。
LoadModule status_module modules/mod_status.so
<IfModule mod_status.c>
ExtendedStatus On
</IfModule>

<Location /server-status>
SetHandler server-status
</Location>
配置完成，重启web服务器之后，使用“http://ip/server-status?refresh=10”查看。refresh=10表示刷新频率为秒钟。或使用“http://ip/server-status?refresh=auto”查看汇总信息。
默认的httpd.conf相关描述：
# Allow server status reports generated by mod_status,
# with the URL of http://servername/server-status
# Change the ".example.com" to match your domain to enable.
#
#<Location /server-status>
# SetHandler server-status
# Order deny,allow
# Deny from all
# Allow from .example.com
#</Location>

## Turn on extended status by default when mod_status is enabled
##
# 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.
#
#LoadModule status_module modules/mod_status.so
<IfModule mod_status.c>
ExtendedStatus On
</IfModule>
