Rare project developers

[Maria Del Carmen Misa Moreira <>]

Hi all,

I'm creating some Grafana dashboards by using Prometheus DB. 
I have data on ifaces-hw-byte-tx/rx but not on ifaces-hw-pack-tx/rx, any idea 
about this? Maybe the sensors changed again or something like that.

Best regards,
Carmen Misa
