Installation

pip install openvpn-status-reader

Don’t forget to put it in setup.py / requirements.txt.

Getting Started

You could configure your OpenVPN server to log for client status. In usual it could be achieved by adding status /path/to/openvpn-status.log line to /etc/openvpn/openvpn.conf. For example:

proto udp
port 1194
dev tun0
status /var/run/openvpn-status.log

Once OpenVPN server running, the log file will be created and written. It looks like:

OpenVPN CLIENT LIST
Updated,Thu Jun 18 08:12:15 2015
Common Name,Real Address,Bytes Received,Bytes Sent,Connected Since
foo@example.com,10.10.10.10:49502,334948,1973012,Thu Jun 18 04:23:03 2015
bar@example.com,10.10.10.10:64169,1817262,28981224,Thu Jun 18 04:08:39 2015
ROUTING TABLE

192.168.255.134,foo@example.com,10.10.10.10:49502,Thu Jun 18 08:12:09 2015
192.168.255.126,bar@example.com,10.10.10.10:64169,Thu Jun 18 08:11:55 2015
GLOBAL STATS
Max bcast/mcast queue length,0
END

Now we could parse log file with this library:

from openvpn_status import parse_status

with open("/var/run/openvpn-status.log") as logfile:
    status = parse_status(logfile.read())

print(status.updated_at)  # datetime.datetime(2015, 6, 18, 8, 12, 15)

foo_client = status.client_list["169.254.0.1"]
print(foo_client.common_name)  # foo@example.com
print(foo_client.bytes_received)  # 334.9 kB
print(foo_client.bytes_sent)  # 2.0 MB
print(int(foo_client.bytes_sent))  # 2097152
