Changing the (automatically discovered) port speed (ifSpeed) of 160.000.000.000 to 200.000.000.000 does not help.
What else can we do?
Thanks for any help!

I did. Got a bit further: the values for the outgoing packets are missing, the incoming are there and are shown in the graph. For the coming 24h (the overload is expected again tonight) I am running a snmpget every few seconds. I’ll check and report back tomorrow.

Perhaps it doesn’t store it after reaching the RRD limit.
Did you run RRDTune after changing the ifSpeeds and wait for the graph to re-draw?
see
When traffic on a LAG reaches above 100G the graph is zeroed out
Hi Chas,
thanks, looks like the same issue. Good catch. I will try the solution.
Reporting back on the snmpget we ran last night : it shows expected values continuously and the rrd file shows the same ‘nan’ gap, so the device is reporting ok, the values arrive in libre but do not end up correct in the rrd.
Solution worked.
Thanks again, Chas.
Jan.
