Not sure what you mean by adding an interface but if you mean a new network port to the actual LibreNMS server then this is unrelated to that I’m sure.

However you can’t get data back, we only store it in rrd so if those files have gone or been changed then that’s it.

Do you actually mean ALL graphs though or just port graphs for one device?

Thanks for the reply
sorry, i was adding an network port to librenms server.

Librenms was only graphing 1 device so far, so i missed ALL ports graph of the device.

Most likely the ifindex has changed. You will find the old ports in the rrd/$hostname/port-id*.rrd. Most likely if you rename the old named one (shown with an older modified date/time) over the new one it will show up.

Also look in the docs for port association mode, you will need to set it to ifName.

hi Iaf,
i read somewhere you mentioned when deleting a device, graphs are not deleted completely, can you help me to recover if possible the graph from January,
looking under /opt/librenms/rrd/device, it appear only graph of April

When deleting a device it does delete the graph data (rrd files). If for some reason it hasn’t, just re-add the device and the old files be used.

Dear laf,
Basically, we lost all the graphs after adding a network interface card. We can only see the graphs after that upgrade. Is there a way to recover old graphs? Where does LibreNMS store all old graphs? how do we do a copy/backup of all those graphs for future reference.

Thanks for your guidance
