349 You many need to check these:
351 1. The package uuid-dev (or libuuid-devel) has to be installed.
353 If your system cannot find libuuid, although it is installed
354 run me with the option: --libs-are-really-here

965 Version update check warning
967 The way you downloaded netdata, we cannot find its version. This means the
968 Update check on the dashboard, will not work.

986 apps.plugin needs privileges
988 Since you have installed netdata as a normal user, to have apps.plugin collect
989 all the needed data, you have to give it the access rights it needs, by running
990 either of the following sets of commands:
992 To run apps.plugin with escalated capabilities:
994 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
995 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
996 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
998 or, to run apps.plugin as root:
1000 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1001 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1003 apps.plugin is performing a hard-coded function of data collection for all
1004 running processes. It cannot be instructed from the netdata daemon to perform
1005 any task, so it is pretty safe to do this.
