To have Netdata re-discover data sources, you need to restart it. There are a few exceptions to this: - containers and VMs are auto-detected forever (when Netdata is running at the host). - many data sources are collected but are silenced by default, until there is useful information to collect (for example network interface dropped packet, will appear after a packet has been dropped). - services that are not optimal to collect on all systems, are disabled by default. - services we received feedback from users that caused issues when monitored, are also disabled by default (for example, `chrony` is disabled by default, because CentOS ships a version of it that uses 100% CPU when queried for statistics). -Once a data collection source is detected, netdata will never quit trying to collect data from it, until Netdata is restarted.

So, if you stop your web server, Netdata will pick it up automatically when it is started again.
