94 netdata will be installed in /opt/netdata

103 Do not wait for the user to press ENTER.

109 If you get errors about missing zlib,

111 you have a broken pkg-config.
112 Use this option to allow it continue

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
359 run me with the option: --libs-are-really-here
361 3. You need basic build tools installed, like:
363 gcc make autoconf automake pkg-config

1217 apps.plugin needs privileges
1219 Since you have installed netdata as a normal user, to have apps.plugin collect
1220 all the needed data, you have to give it the access rights it needs, by running
1221 either of the following sets of commands:
1223 To run apps.plugin with escalated capabilities:
1225 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1226 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1227 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1229 or, to run apps.plugin as root:
1231 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1232 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1234 apps.plugin is performing a hard-coded function of data collection for all
1235 running processes. It cannot be instructed from the netdata daemon to perform
1236 any task, so it is pretty safe to do this.
