400G Ports and snmp

Hello
we have a problem with 400g ports on arista and on cisco 8201 devices, when the device reaches more than 100GB util, the graphs are blank as you can see in the picture

Hello,
See if this works for you.

RRDTune - LibreNMS Docs

i have it turned on and it actually recognizes the port as 400gbps but wont show the graph when traffic reach 100gb

[SantiagoSilvaZ]

Now, see if the script solves the problem.

./scripts/tune_port.php -h <hostname> -p <ifName>

Note: The failure of the previous graph will continue as it was not saved in the RRD file. The graph will show correct in future records.

Make sure port speed is reflected correctly for the port too, that is what determines the new max value.

[axsis_leet]

but the max value was OK and as it should be… i ran the script
will let you know soon

[axsis_leet]

the script indeed solved our problem
the graphs are now showing proper usage
