Old Netgear switches, graphs incorrect

[DJerry]

Hello,

I’m trying to monitor some old Netgear switches however the graph data is incorrect.
Switch model is Netgear FS728TS

Current speed can show as 180 Pbps on a 100Mbps-interface.

And below graph is very wrong.

Cacti is graphing correct if i use non 64-bit counters.

Can I do anything to fix this?

Thanks in advance

See here -> https://docs.librenms.org/#Support/FAQ/#faq15 you need to enable rrdtune for that device and run the scripts.

Thanks for the fast reply!

Tried enabling RRDTune on one device and then ran script on all ports for that host.
Still same error.

Also this thread popped up in Suggested Threads. Seems like same problem with same switches.

FS700TS Switch stack port traffic/troughput incorrect

Hey guys. we have two netgear switch stacks which are fast ethernet (except for trunking ports) but librenms routinely thinks it has troughputs of Pbps on 100Mbit ports (which of course is rediculous) [image] Please let me know what further information you need to tackle this issue or should I change some setting to fix this?
