CPU Utilization on our servers
what does it take so much CPU?
The site iplists.firehol.org is maintained by FireHOL - the CPU is used for comparing security IP Lists.
CPU Usage of the netdata user
netdata monitors users, user groups, applications (process trees)
and containers (lxc, docker, etc.)
EU - London, CPU % of a single core
US - Atlanta, CPU % of a single core
EU - Greece, CPU % of a single core
this utilization is about the whole netdata process tree and the percentage is of a single core!
including BASH plugins (it monitors mysql on the demo sites), node.js plugins (it monitors bind9 on the demo sites), etc.
and including the chart refreshes for the dashboards of all viewers.
