Example of query for total traffic (sum all servers in a site with In/Out traffic):

# prometheus.XX.grapeshot.co.uk:9090 from Cam
sum(irate(node_netstat_IpExt_InOctets{instance=~"^.*nj\\.grapeshot\\.co\\.uk"}[5m]) + irate(node_netstat_IpExt_OutOctets{instance=~"^.*nj\\.grapeshot\\.co\\.uk"}[5m]))*8/1000000000

• Exporter (in the server/device to be monitored)
  • node exporter (linux box)
  • snmp exporter (really anything)
• Dashboard
  • Grafana
• Alert
  • YAML configuration for prometheus

cardinality in lables (?)
prometheus stores its data in a time series database
