Network Metrics

The Network metric group contains per-node metrics regarding network activity. The metrics available are:

• Network in
• Network out

While PostgreSQL performance bottlenecks are more likely to be related to memory, CPU or disk performance, network throughput can also be a factor. The network traffic metrics can be a useful tool to identify where bottlenecks lie.

Network in

This metric shows the difference between the number of bytes received over the network since the last metric.

You can also get this metric through the Monitoring API  with the query parameter metrics=n::networkindelta

Network out

This metric shows the difference between the number of 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
