Muninを入れて、Apacheを通してログを確認する所までは問題無く行けたのですが、
グラフをCGIで動的に生産するために、色々と試行錯誤してみても、エラーが出たまま一向に前に進まず、途方に暮れています……
どうか……みなさまのお力添えを頂けると幸いです。

# This is the main Apache server configuration file. It contains the # configuration directives that give the server its instructions. # See http://httpd.apache.org/docs/2.4/ for detailed information about # the directives and /usr/share/doc/apache2/README.Debian about Debian specific # hints. # # # Summary of how the Apache 2 configuration works in Debian: # The Apache 2 web server configuration in Debian is quite different to # upstream's suggested way to configure the web server. This is because Debian's # default Apache2 installation attempts to make adding and removing modules, # virtual hosts, and extra configuration directives as flexible as possible, in # order to make automating the changes and administering the server as easy as # possible. # It is split into several files forming the configuration hierarchy outlined # below, all located in the /etc/apache2/ directory: # # /etc/apache2/ # |-- apache2.conf # | `-- ports.conf # |-- mods-enabled # | |-- *.load # | `-- *.conf # |-- conf-enabled # | `-- *.conf # `-- sites-enabled # `-- *.conf # # # * apache2.conf is the main configuration file (this file). It puts the pieces # together by including all remaining configuration files when starting up the # web server. # # * ports.conf is always included from the main configuration file. It is # supposed to determine listening ports for incoming connections which can be # customized anytime. # # * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/ # directories contain particular configuration snippets which manage modules, # global configuration fragments, or virtual host configurations, # respectively. # # They are activated by symlinking available configuration files from their # respective *-available/ counterparts. These should be managed by using our # helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See # their respective man pages for detailed information. # # * The binary is called apache2. Due to the use of environment variables, in # the default configuration, apache2 needs to be started/stopped with # /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not # work with the default configuration. # Global configuration # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE! If you intend to place this on an NFS (or otherwise network) # mounted filesystem then please read the Mutex documentation (available # at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>); # you will save yourself a lot of trouble. # # Do NOT add a slash at the end of the directory path. # #ServerRoot "/etc/apache2" # # The accept serialization lock file MUST BE STORED ON A LOCAL DISK. # Mutex file:${APACHE_LOCK_DIR} default # # PidFile: The file in which the server should record its process # identification number when it starts. # This needs to be set in /etc/apache2/envvars # PidFile ${APACHE_PID_FILE} # # Timeout: The number of seconds before receives and sends time out. # Timeout 300 # # KeepAlive: Whether or not to allow persistent connections (more than # one request per connection). Set to "Off" to deactivate. # KeepAlive On # # MaxKeepAliveRequests: The maximum number of requests to allow # during a persistent connection. Set to 0 to allow an unlimited amount. # We recommend you leave this number high, for maximum performance. # MaxKeepAliveRequests 100 # # KeepAliveTimeout: Number of seconds to wait for the next request from the # same client on the same connection. # KeepAliveTimeout 5 # These need to be set in /etc/apache2/envvars User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} # # HostnameLookups: Log the names of clients or just their IP addresses # e.g., www.apache.org (on) or 204.62.129.132 (off). # The default is off because it'd be overall better for the net if people # had to knowingly turn this feature on, since enabling it means that # each client request will result in AT LEAST one lookup request to the # nameserver. # HostnameLookups Off # ErrorLog: The location of the error log file. # If you do not specify an ErrorLog directive within a <VirtualHost> # container, error messages relating to that virtual host will be # logged here. If you *do* define an error logfile for a <VirtualHost> # container, that host's errors will be logged there and not here. # ErrorLog ${APACHE_LOG_DIR}/error.log # # LogLevel: Control the severity of messages logged to the error_log. # Available values: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the log level for particular modules, e.g. # "LogLevel info ssl:warn" # LogLevel warn # Include module configuration: IncludeOptional mods-enabled/*.load IncludeOptional mods-enabled/*.conf # Include list of ports to listen on Include ports.conf # Sets the default security model of the Apache2 HTTPD server.

自分でも色々調べて試してみましたが、一向に前に進む気配がありません。
みなさまの知恵と技術をお借り出来ればと思います。
