+You are attempting to install netdata as non-root, but you plan to install it

+
+Please set an installation prefix, like this:

+
+ sudo $0 ${@}
+
+We suggest to install it as root, or certain data collectors will not be able

+apps.plugin needs privileges
+
+Since you have installed netdata as a normal user, to have apps.plugin collect
+all the needed data, you have to give it the access rights it needs, by running
+these commands:
+
+ sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
+ sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"

+The commands allow apps.plugin to run as root.
+
+apps.plugin is performing a hard-coded function of data collection for all
+running processes. It cannot be instructed from the netdata daemon to perform
+any task, so it is pretty safe to do this.
