[mrtg] Reporting Through MRTG...

In theory, MRTG can graph anything for which you can give it the data.


The problem in this case is, how to OBTAIN the data?  MRTG uses SNMP or
custom-written plugins to collect data.  Normal SNMP will only give you the
data throughput for a port, not split by source or port.  To do this, you’
ll need to have something else collecting the data.


The way I do it at home is to route all internet traffic via my Linux
firewall.  This has various iptables rules to count packets based on
internal IP (you could also count by port, of course); I then have a custom
plugin for MRTG that pulls values from the iptables stats, allowing me to
graph which PC in the house is using how much of our bandwidth.


In a commercial setting, you may have an RMON probe that can be used to get
this data, or a switch/router with RMON capabilities.  Or, you can have a
traffic sniffer on a span port somewhere collecting the data.  In any case,
you’d have to make a homegrown method to extract the counts.


Other applications (many requiring money) exist to give you this finer
traffic analysis, and these may suit your purpose better.

We are using MRTG 2.9.17 version on Windows 2003 Server Platform, everything
is working fine but our requirements is to monitor the user activity through
MRTG, is there any way to monitor each user activity about the bandwidth
utilization and all http/https sessions, I would appreciate for your
valuable advise.
