Solarflare traffic graph broken for extra PFs

stephenw10

There's probably not much we can do about this if the driver does not report the stats as expected for the virtual NICs.
Do you see traffic logged in the RRD graphs? (Status > Monitoring)
Or from iftop at the command line?

@stephenw10 Is this the RRD Graph?

stephenw10

It is. I assume LAN is assigned as one of the virtual interfaces there?

netnerdy

@stephenw10 yup.

stephenw10

Hmm, how do those interfaces appear in, say, ifconfig?

Was ifconfig output helpful? :)

stephenw10

Not really, they look to be presented almost identically.

I would look at the interface stats in the sysctls. Make sure they are incrementing Equally across both NIC types. They may not even be defined for the virtual NICs.

@stephenw10

You’re right about sysctl. I guess no fix for this, right?

[2.5.2-RELEASE][root@pfSense.home]/root: sysctl -a | grep sfxge.1.stats.tx_pkts
dev.sfxge.1.stats.tx_pkts: 0
[2.5.2-RELEASE][root@pfSense.home]/root: sysctl -a | grep sfxge.0.stats.tx_pkts
dev.sfxge.0.stats.tx_pkts: 76506024

stephenw10

Probably not in pfSense, it looks like a driver issue.

Unless there is some other sysctl that can alter that behaviour. I don't see anything listed though.
