That value is the ports IfIndex as reported by IF-MIB and is kept in `ifIndex` in the ports table.

Hi,

I would like to do some rrdtool fetch against the raw rrd files observium generated to get some reports. But I couldn’t figure out how to match the portid or device_id from observium tables to get the correct path to match to the rrd files.

Rrd files location seemed to be at ~observium/rrd/devicenames. But the rrd file name like port-123.rrd, 123 seems not to be the port_id in the ports table. Rather it’s device specific.

Thank you very much for your help.
