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

1159 apps.plugin needs privileges
1161 Since you have installed netdata as a normal user, to have apps.plugin collect
1162 all the needed data, you have to give it the access rights it needs, by running
1163 either of the following sets of commands:
1165 To run apps.plugin with escalated capabilities:
1167 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1168 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1169 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1171 or, to run apps.plugin as root:
1173 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1174 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1176 apps.plugin is performing a hard-coded function of data collection for all
1177 running processes. It cannot be instructed from the netdata daemon to perform
1178 any task, so it is pretty safe to do this.
