Strange spikes on the traffic graphs

Hello. Could anyone help to solve the problem with crazy spikes on the traffic graphs?
I tried to enable RRD Tune for all ports of this device, but it doesn’t work and these spikes are going to appear again. I noticed that this problem belongs only to eth1 interfaces.

Hi :slight_smile:

Check your interface speeds under “Edit Device → Port Settings” , make sure it is set to the correct interface speed.

After enabling RRD tune, did you also run the script against the device ?

e.g
./scripts/tune_port.php -h 1.1.1.1

You will need to wait for the graph to redraw as i dont think it fixes history.

#RRDTune - LibreNMS Docs

If you still see a large spike, i think the next step is to run an snmpwalk to check what values the device is returning.

Hello. Thanks for your reply.

Didn’t run the script tune_port.php, seems to be much better, but anyway it should be run regularly.

Thank you.
