えっと、上記を参考にして、Muninは設置出来ているものとします。( ´▽`)ノ
*WWWサーバをMuninで監視するよ! [#n4bb30ac]
といえば、当然用意されているプラグインの、Apache関連を使いたい。よね。で、普通に、
blackcube# munin-node-configure -suggest
すると、

amavis | no | no
apache_accesses | no | no [apache server-status not found. check if mod_status is enabled]
apache_processes | no | no [apache server-status not found. check if mod_status is enabled]

となります。(ーー;)

**munin-node-configure -suggest [#e78260c9]
というコマンドのソースを見てませんが、プラグイン実行時のエラーを上げている様です。で、
[apache server-status not found. check if mod_status is enabled]
に対処するわけですが・・・。まず、server-statusを表示させます。
/usr/local/etc/apache22/httpd.conf
# Real-time info on requests and configuration
Include etc/apache22/extra/httpd-info.conf
で、ついで、該当のetc/apache22/extra/httpd-info.confを、
# Get information about the requests being processed by the server
# and the configuration of the server.
#
# Required modules: mod_status (for the server-status handler),
# mod_info (for the server-info handler)
#
# 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.
ScriptAlias /server-status/ ":80/server-status/"
<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from 127.0.0.1
Allow from .smb.net
</Location>
#
# 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.
#
ExtendedStatus On
#
# 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.
#
<Location /server-info>
SetHandler server-info
Order deny,allow
Deny from all
Allow from 127.0.0.1
Allow from .smb.net
</Location>
とします。
ScriptAlias /server-status/ ":80/server-status/"
とするのは、Muninのプラグインが、url:80 でアクセスする事を想定しているからです。
/usr/local/etc/munin/plugin-conf.d/plugin.conf
[apache_*]
env.url http://127.0.0.1:%d/server-status?auto
#env.url http://127.0.0.1/server-status?auto
env.ports 80
これで、
Plugin | Used | Suggestions
------ | ---- | -----------
amavis | no | no
apache_accesses | yes | yes
apache_processes | no | no
apache_volume | yes | yes
となったと思います。あとは、プラグインのリンクを
blackcube# munin-node-configure -shell | sh
で自動生成する、ヨロシ(o゜▽゜)o
http://sunq.jp/style/archives/2012/02/19-165504
apache_processes | no | no
となっていたwww.smb.netですが、他のG7機体ではyesとなってます。ためしに、プラグイン入れて見ると、
blackcube# cat /var/log/munin/munin-node.log
