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

358 If your system cannot find zlib, although it is installed

361 3. You need basic build tools installed, like:
363 gcc make autoconf automake pkg-config

1050 Update check on the dashboard, will not work.

1068 apps.plugin needs privileges
1070 Since you have installed netdata as a normal user, to have apps.plugin collect
1071 all the needed data, you have to give it the access rights it needs, by running
1072 either of the following sets of commands:
1074 To run apps.plugin with escalated capabilities:
1076 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1077 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1078 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1080 or, to run apps.plugin as root:
1082 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1083 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1085 apps.plugin is performing a hard-coded function of data collection for all
1086 running processes. It cannot be instructed from the netdata daemon to perform
1087 any task, so it is pretty safe to do this.
