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

1151 The way you downloaded netdata, we cannot find its version. This means the
1152 Update check on the dashboard, will not work.

1170 apps.plugin needs privileges
1172 Since you have installed netdata as a normal user, to have apps.plugin collect
1173 all the needed data, you have to give it the access rights it needs, by running
1174 either of the following sets of commands:
1176 To run apps.plugin with escalated capabilities:
1178 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1179 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1180 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1182 or, to run apps.plugin as root:
1184 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1185 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1187 apps.plugin is performing a hard-coded function of data collection for all
1188 running processes. It cannot be instructed from the netdata daemon to perform
1189 any task, so it is pretty safe to do this.
