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

1011 Version update check warning
1013 The way you downloaded netdata, we cannot find its version. This means the
1014 Update check on the dashboard, will not work.
1016 If you want to have version update check, please re-install it
1017 following the procedure in:

1032 apps.plugin needs privileges
1034 Since you have installed netdata as a normal user, to have apps.plugin collect
1035 all the needed data, you have to give it the access rights it needs, by running
1036 either of the following sets of commands:
1038 To run apps.plugin with escalated capabilities:
1040 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1041 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1042 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1044 or, to run apps.plugin as root:
1046 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1047 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1049 apps.plugin is performing a hard-coded function of data collection for all
1050 running processes. It cannot be instructed from the netdata daemon to perform
1051 any task, so it is pretty safe to do this.
