+# Plugin for monitor oracle database reads.
+#
+# Licenced under GPL v2.
+#
+# Usage:
+#
+#       Symlink into /etc/munin/plugins/ and add the monitored
+#       database to the filename. e.g.:
+#
+#       ln -s /usr/share/munin/plugins/oracle__database__hitratio \
+#         /etc/munin/plugins/oracle_<databasename>_database__hitratio
+#       This should, however, be given through autoconf and suggest.
+#
+#       If required, give username, password and/or Oracle server
+#       host through environment variables.
+#
+#
+# Parameters:
+#
+#       config   (required)
+#
+# Config variables:
+#
+#       dbhost     - Which database server to use. Defaults to
+#                    'localhost'.
+#       dbname     - Which database to use. Defaults to orl1
+#       dbuser     - A Oracle user account with read permission to
+#                    the given database. Defaults to
+#                    'oracle'. Anyway, Munin must be told which user
+#                    this plugin should be run as.
+#       dbpass     - The corresponding password, if
+#                    applicable. Default to undef.
+#
+# Magic markers
+#%# family=auto
+#%# capabilities=autoconf
