 Because Require local was changed to all, you can view stats instead of a 403.
-To change servername on graphs from: localhost.localdomain
+==== Change servername on graphs====
 <code>
 vi /etc/munin/munin-node.conf
 #uncomment and update to:
 host_name server.domain.com
+</code>
+<code>
+vi /etc/munin/munin.conf
+#Change
+#[localhost.localdomain]
+#to
+[server.domain.com]
+    address 127.0.0.1
+    use_node_name yes
 </code>
 ...A few minutes later, you should see updates.
+==== Removing graphs / plugins ====
+All possible plugins are stored in: /usr/share/munin/plugins/ and symlinked into: /etc/munin/plugins
+To delete a plugin, simply delete it from /etc/munin/plugins
+==== Adding graphs / plugins ====
+=== Apache plugins ===
+<code>
+ln -s /usr/share/munin/plugins/apache_accesses /etc/munin/plugins/apache_accesses
+ln -s /usr/share/munin/plugins/apache_processes /etc/munin/plugins/apache_processes
+ln -s /usr/share/munin/plugins/apache_volume /etc/munin/plugins/apache_volume
+ln -s /usr/share/munin/plugins/port_ /etc/munin/plugins/port_80
+#You may need to do:
+a2enmod status
+#reported: Module status already enabled
+#check /etc/apache2/mods-enabled/status.conf
+</code>
+Note: there are lots more graphs for apache, but require apache mod_watch. See [[munin_statistics#apache_mod_watch_munin_graphs_showing_vhost_accesses|here]]
+=== SQL plugins ===
+Well MySQL is now MariaDb.
+<code>
+ln -s /usr/share/munin/plugins/mysql_queries /etc/munin/plugins/mysql_queries
+ln -s /usr/share/munin/plugins/mysql_slowqueries /etc/munin/plugins/mysql_slowqueries
+ln -s /usr/share/munin/plugins/mysql_bytes /etc/munin/plugins/mysql_bytes
+</code>
+=== Other useful plugins ===
+<code>
+ln -s /usr/share/munin/plugins/postfix_mailstats /etc/munin/plugins/postfix_mailstats
+ln -s /usr/share/munin/plugins/multips_memory /etc/munin/plugins/multips_memory
+^ For the above, to monitor just certain processes
+vi /etc/munin/plugin-conf.d/munin-node
+#Add
+[multips_memory]
+env.names apache2 mariadbd
+</code>
