Hi all,
this patch does only works if the common name is the same then the
connection name. Have encountered that the rrd creation for OpenVPN
uses the common name of the certificate not the connection name -->

# root @ ipfire-server in /var/log/rrd/collectd/localhost [8:34:50] 
$ ls
cpu-0      disk-loop0                 iptables-filter-PSCAN  processes-charon    processes-spamd
cpu-1      disk-sda                   load                   processes-java      processes-squid
cpu-2      entropy                    memory                 processes-mpd       processes-squidguard
cpu-3      interface                  openvpn-rwonecert      processes-nmbd      processes-sshd
cpufreq    iptables-filter-NEWNOTSYN  openvpn-rwtwocert      processes-openvpn   sensors-coretemp-isa-0000
disk-dm-0  iptables-filter-POLICYFWD  ping                   processes-qemu      sensors-f71869-isa-0290
disk-dm-1  iptables-filter-POLICYIN   processes              processes-rtorrent  swap
disk-dm-2  iptables-filter-POLICYOUT  processes-asterisk     processes-smbd

$ cat /var/ipfire/ovpn/ovpnconfig 
1,on,rwonename,rwonecert,host,cert,,,,,,,,,,,,,,,,,,,,,,,,,,,,dynamic
2,on,rwtwoname,rwtwocert,host,cert,,,,,,,,,,,,,,,,,,,,,,,,,,,,dynamic,,,,,,,,,,,

strangely enough if i set the element index to [2] it doesn´t work. Currently not sure why that´s happen.

It is better to revert this patch.

Best,

Erik
