Network | Cassandra Documentation
The Network metric group contains per-node metrics regarding network activity. The metrics available are:
- Network in
- Network out
These metrics traffic can indicate if certain nodes are bearing more load due to traffic or repairs. This can otherwise be hidden under some circumstances (eg, uneven partition size or batch size).
Network in
This metric shows the difference between the number of the bytes received over the network since the last metric.
You can also get this metric through the Monitoring API with the query param metrics=n::networkindelta
Network out
This metric shows the difference between the number of the bytes sent over the network since the last metric.
You can also get this metric through the Monitoring API with the query param metrics=n::networkoutdelta
