Network unit measure on Node Exporter Full #37

Closed yiskaneto closed 4 years ago

yiskaneto commented 5 years ago

Hello,

Network speed is measure on bits per second not bytes. The metrics collected by node_exporter are given in bytes, for example: node_network_receive_bytes_total This needs to be multiplied by 8 to get the real value in bits. To be more specific, the "Network Traffic Basic" has the following query: irate(node_network_receive_bytes_total{instance=~"$node:$port",job=~"$job"}[5m]) This query shows the data as it's given by the node_exporter, in other words in bytes.

The query should be: irate(node_network_receive_bytes_total{instance=~"$node:$port",job=~"$job"}[5m])*8

As a consequence of this, the "unit measure" to show the data in the left "Y" axis needs to be change to "bits/sec" under "data rate": image

You are right, it is changed on last commit.

Thanks,
