[Resolved] Counter64 For Linux in / out

Help
1

I have a couple of heavily loaded VMs, which I cannot reboot ideally.

My TX/RX packet count in ifconfig far exceeds a 32 bit number, meaning my snmp data is very sporadic.

How can I make use of the MIBs at 1.3.6.1.2.1.31.1.1.1 so I can use the Counter64 values instead of the Counter32 values for monitoring eth0 in/out packets?

Thanks

I have managed to fix this using an SNMPd config on my Linux VMs.

I basically exclude the counter32 values for the interface MIBs.

Example from snmpd.conf

## LibreNMS MIBs (restricted for faster polling)

view    libre-mibs      excluded        .1.3.6.1.2.1.2.2.1.19

This seems to force the usage of the 64 bit counters instead of 32 bit counters.

For ref, also fixes miscalculated port speeds in TP-Link Jetstream T1700G-28TQ

I also added as an include: 1.3.6.1.4.1.11863.6.4.1 specifically for TPLInk CPU and RAM stats
