+ 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
+ either of the following sets of commands:
+
+ To run apps.plugin with escalated capabilities:
+
+ sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
+ sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
+ sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
+
+ or, to run apps.plugin as root:
+
+ sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
+ sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
+
+ 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.
