How can I log / monitor the used bandwidth externally?

MatthiasGinster

Hey everyone,
As the topic says, I'm searching for a way to log the utilization of my network externally.
So I found this: https://community.sophos.com/products/unified-threat-management/f/management-networking-logging-and-reporting/31918/monitor-bandwidth-usage, bus as far as I can see, IPTraf will only give me insights when I log into the console.
I'd prefer in the most simple way something which logs it into a file.

I wouldn't even care (but instead prefer!) if it would write just a single line into a text file and overwrite it continuously.
On my network, I got a media server with some friends beeing able to access media from it via my internet connection.
I don't care what they do - but would be interested to see how much my PPPoE is utilized throughout the day.

As I use home automation, I could parse this line with the home automation server software I use (IP-Symcon), this could be written into a variable and displayed in nice graphs and do all kind of calculations.

Do you have any idea what I could do? I even enabled syslog-logging, but from what I've seen so far, this information is not useful at all.
Regards,
Matthias

    Matthias, that thread is over ten years old, and a lot of capability has been added.  Look at the 'Bandwidth Usage' tab in 'Logging & Reporting >> Network Usage'.

    If the access is always via HTTP/S, then, with some extra effort, you could use the custom, automatically-emailed reports in 'Logging & Reporting >> Web Protection'.  If you're interested in that, please open a new thread with that question.

    Cheers - Bob

    Thanks for the hint - but I already knew both of it.
    My idea is to log / view this data live, maybe even on the go - without using VPN, logging in etc.
    I'd like to get the data outside of UTM somehow - isn't there any idea / solution.
    Regards,
    Matthias

    Hi Matthias,

    The monitoring is possible via graphs and reports as mentioned by Bob. I don't think an additional feature will be incorporated when an alternative is available. You can still raise it as a feature request here and cast your votes.

    Fingers crossed.

    I'm not using it - but I know a lot of people / companies use NAGIOS, so they can get the syslog-info. But this would not help them to have the utilization info in one place.
    Same for me - its not Nagios - but I try to have it integrated in the (quite powerful) home automation.

    Thanks,

    so I checked for alternatives...
    What do you guys think of SNMP? With SNMPWALK I've seen that there are pages over pages of data!
    The only problem I got is, I can not find the bandwidth currently used (or any average).

    So the MIB database is not helpful at all - it just represents ~10% of the data seen with SNMPWALK. 

     

    But within all this data (I tried two tools) GetIF & OiDView, I haven't found the appropriate values. I mean, I'd "take" everything - a percentage, a bit value, a byte value etc.

    Anyone that can help here to find the right OIDs?
    The only I found which are related to anything close to the speed are the transferred octects (in & out) but in my opinion, the polling time is a major factor here - so I'd rather use anything else if possible.
    The "interface speed" just gives the optimum / rated speed of the interfaces (for e.g. mine are each 1Gbit/s)

    Matthias, I don't think the information is available from the UTM via SNMP.  Have you considered iView?  What about IPFIX which is configured on the 'Settings' tab of 'Logging & Reporting >> Reporting Settings'?  Could you get what you need with something like Splunk and 'Remote Syslog'?

    Cheers - Bob

    I beg to differ.

    I managed it - and so can all other as well with whatever tool, it needs a command line utility which gives back an answer.

    So I inquire every 60 seconds for the updated values of octets in an out for my eth0. (PPPOE interface OID changes with every reconnection attempt)

    I deduct the value collected 60 seconds earlier from the new one. The result is the 60 seconds average bytes.

    This gets multiplied with 8 (bits) and divided by 60 000 000.

    This will give me the Mbit/s average for each minute.

    Hope this can help anyone else that wants to log the speed like me.

    Regards,

    Matthias

    Hi Balfson,

     

    I just saw that I forgot to answer, what I'm doing in the Software (IP-Symcon, programmed in PHP) is in the Code that follows, it is using SNMP and faily simple.
    In fact I just check every 60s about the Bytes sent and received and calculate the Delta, which is divided by 60. Thisi s my Speed.
    Sorry that the variables are in german partially, but I'm german :-) I guess you can still understand what the script does.
