Hello,
I have installed grafana and nodeexporter on my infrastructure.
I would like to display the 95th percentile of the bandwidth of my instance because my host charges it if I exceed a certain threshold.
I found the metrics node_network_receive_bytes_total and node_network_transmit_bytes_total which correspond to the total bytes received / sent by the node.
I created 2 queries to calculate 95% of the lowest values on the network every 5 minutes:
quantile(0.95, sum(irate(node_network_receive_bytes_total{instance=“my-instance”,job=“nodeexporter”}[5m]))) * 8)
quantile(0.95, sum(irate(node_network_transmit_bytes_total{instance=“my-instance”,job=“nodeexporter”}[5m])) * 8)
I have some values displayed, but I don’t know if they are the right values. What do you think?
Do you know how to check that it’s returning the right values?
Thank you very much for your help!
