Displaying uptime OpenVPN client

[Intrepid2007]

Unfortunately, the uptime is not available at the page where OpenVPN client statistics are shown.

Is there another way to find this info? Maybe via telnet? I have a RT-AX88U

Thanks

The VPN Client '/etc/openvpn/clientX/status' file does not track/contain the UP time

However, a crude method would be to manually record the VPN Client initialised time (to a file) using the openvpn-event 'vpnclientX-up' trigger script

e.g. VPN Client 4

VPN_ID=4;echo "$(date "+%F %T")" > /tmp/vpnclient$VPN_ID.log

then when appropriate you can simply compare the timestamp in '/tmp/vpnclient$VPN_ID.log' to the current time to calculate the elapsed duration.

e.g. Determine the TOTAL (PID UP time) in the openvpn-event vpnclientX-down trigger script.

Alternatively you could use a SyslogEventMonitor script to track the VPN Client events and calculate the actual duration in more detail.

Thank you for your reply...
Unfortunately I am not familiar with scripting and how to implement it in Asus routers..

Indeed, the SyslogEventMonitor has this information. I could configure the router to send it's log data to a utility that analyses the log data. I am interested how stable is the vpn connection and the uptime is an indication. Writing such a utility is not too much work.

Sorry for bringing up an old thread.
I too is curious to know what is my vpn client uptime. Sometimes I find the connection stale and I have to manually reset the vpn connection to get it up again.
Thanks @Martineau, I have added your suggestion to create a time logging. Anyone has develop some script for this?

A script to display the VPN connection session duration, or to detect stale/degraded throughput VPN Client connections?

i.e. To simply display the tracking time, I use the following

# Extract the timestamp from the VPN tracker file

VPN_ID=$1            # Select the appropriate VPN Client instance either dynamically (arg) or static (e.g. 'VPN_ID=5')

if [ -f /tmp/vpnclient${VPN_ID}.log ];then
    SESSION_TIMESTAMP=$(date -r /tmp/vpnclient${VPN_ID}.log +%s)
    CURRENT_TIMESTAMP=$(date +%s)
    echo $(($(date +%s)-$(date -r /tmp/vpnclient${VPN_ID}.log +%s))) | awk '{printf("%d days %02d hours %02d minutes %02d seconds\n",($1/60/60/24),($1/60/60%24),($1/60%60),($1%60))}'
    #echo -e $cBGRE"\n\t\tClient ${VPN_ID} Connected session duration" $(Convert_SECS_to_HHMMSS "$((CURRENT_TIMESTAMP-SESSION_TIMESTAMP))" "daystext")  >&2
else
    echo -e $cBGRE"\n\t\tClient ${VPN_ID} Connected session duration not tracked...missing '/tmp/vpnclient${VPN_ID}.log'. Check 'openvpn-event:vpnclient${VPN_ID}-up'" >&2
fi

e.g.

./VPN_Client_Switch.sh status

(VPN_Client_Switch.sh): 14642 v1.11 Request..... [status]


    VPN Client Status:

        Client 1 Connected session duration 3 days 00 hours 49 minutes 45 seconds
                 Connection 553:udp to 100.120.249.243 (HMA New York)           VPN STUN tunnel end-point I/P: 212.102.33.48

Thanks @Martineau. Perhaps a bit of both is better .
I have two VPN client running. Do I have to specify which VPN client ID or just use it as it is? I try to use it as is, and I am getting some error message. Can you help me see what could be the problem?

./VPN_Client_Switch.sh: local: line 12: not in a function

The code snippet was an example of how to use the VPN Client tracker file.

You said you had modified a script to initialise the tracker so assumed you could understand the snippet.

I have now simply commented out the lines causing you the errors and uncommented the line that should work and added the loop for your two VPN Clients

for VPN_ID in 1 2
    do
        if [ -f /tmp/vpnclient${VPN_ID}.log ];then
            #SESSION_TIMESTAMP=$(date -r /tmp/vpnclient${VPN_ID}.log +%s)
            #CURRENT_TIMESTAMP=$(date +%s)
            #echo $(($(date +%s)-$(date -r /tmp/vpnclient${VPN_ID}.log +%s))) | awk '{printf("%d days %02d hours %02d minutes %02d seconds\n",($1/60/60/24),($1/60/60%24),($1/60%60),($1%60))}'
            echo $(($(date +%s)-$(date -r /tmp/vpnclient${VPN_ID}.log +%s))) $VPN_ID | awk '{printf("VPN Client %d uptime %d days %02d hours %02d minutes %02d seconds\n",($1/60/60/24),($1/60/60%24),($1/60%60),($1%60))}'
            #echo -e $cBGRE"\n\t\tClient ${VPN_ID} Connected session duration" $(Convert_SECS_to_HHMMSS "$((CURRENT_TIMESTAMP-SESSION_TIMESTAMP))" "daystext")  >&2
        else
            echo -e $cBGRE"\n\t\tClient ${VPN_ID} Connected session duration not tracked...missing '/tmp/vpnclient${VPN_ID}.log'. Check 'openvpn-event:vpnclient${VPN_ID}-up'" >&2
        fi
    done

EDIT: Include VPN Client instance in output
e.g.

VPN Client 1 uptime 0 days 00 hours 09 minutes 20 seconds
VPN Client 2 uptime 0 days 00 hours 08 minutes 00 seconds

Thanks again @Martineau. Now I get to see the output.

Edit: Really appreciate your help. The enhanced version to include VPN instance is even better. Now I have it on a cronjob for logging.

Update: Logging is good.
