Diamond is a python daemon that collects system metrics and publishes them to Graphite (and others). It is capable of collecting cpu, memory, network, i/o, load and disk metrics. Additionally, it features an API for implementing custom collectors for gathering metrics from almost any source.

NetworkCollector sends absurd data to grafana #730

Look at the graph. In the time of that peak I have downloaded a 1.8GB file. The graph displays the rx_byte metric of the NetworkCollector. Can someone explains the data which is send to grafana?

If I extract the data of the graph above out of influxdb:

> SELECT rx_byte FROM "network" WHERE ("host" = 'firewall' AND "interface" = 'enp3s0')
name: network
time                rx_byte

The counter is already high... rx_bytes is 430625254007 ... so around 430GB But the counter has increased while downloading the 1.8GB file for that size. I have checked this.

rx_bytes is a rate (bytes per second), not just a counter that increments. If this does not answer your question, reopen.
