1081 Since you have installed netdata as a normal user, to have apps.plugin collect
1082 all the needed data, you have to give it the access rights it needs, by running
1083 either of the following sets of commands:
1085 To run apps.plugin with escalated capabilities:
1087 ${TPUT_YELLOW}${TPUT_BOLD}sudo chown root:${NETDATA_USER} \"${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin\"${TPUT_RESET}
1088 ${TPUT_YELLOW}${TPUT_BOLD}sudo chmod 0750 \"${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin\"${TPUT_RESET}

1091 or, to run apps.plugin as root:
1093 ${TPUT_YELLOW}${TPUT_BOLD}sudo chown root \"${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin\"${TPUT_RESET}
1094 ${TPUT_YELLOW}${TPUT_BOLD}sudo chmod 4755 \"${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin\"${TPUT_RESET}
1096 apps.plugin is performing a hard-coded function of data collection for all
1097 running processes. It cannot be instructed from the netdata daemon to perform
1098 any task, so it is pretty safe to do this.
