For more information on how to create custom graphs, see the graphs section of the documentation site at https://www.zabbix.com/documentation/2.4/manual/config/visualisation/graphs.
Compare containers to your host machine
As we added the Linux OS template and the Docker template to the host and we are also recording quite...
