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

1155 apps.plugin needs privileges
1157 Since you have installed netdata as a normal user, to have apps.plugin collect
1158 all the needed data, you have to give it the access rights it needs, by running
1159 either of the following sets of commands:
1161 To run apps.plugin with escalated capabilities:
1163 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1164 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1165 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1167 or, to run apps.plugin as root:
1169 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1170 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1172 apps.plugin is performing a hard-coded function of data collection for all
1173 running processes. It cannot be instructed from the netdata daemon to perform
1174 any task, so it is pretty safe to do this.
