I am monitoring the bandwidth utilization of every interface in each router. During the configuration nagiosxi shows you the max speed of each interface, however I am not seeing those numbers in mysql. Do you have any idea?

By that do you mean the theoretical maximum (eg. 1 Gbps), or the highest it's actually been (eg. 637 Mbps)?

That would be the ifSpeed returned by SNMP, OID 1.3.6.1.2.1.2.2.1.5

I really did not get it. Is the max speed store in the database?

The max speed for each port is retrieved from your switch, I'm not sure where exactly it's stored. You could check /var/www/mrtg/mrtg.cfg and see if it's stored in there.

It is not there and I really need it in order to perform some percentage bandwidth utilization of each interfaces.

If it's not stored, you can always fetch again yourself -
