If you get errors about missing zlib,
- but you know it is available,
+ or libuuid but you know it is available,
you have a broken pkg-config.
Use this option to allow it continue
without checking pkg-config.
Netdata will by default be compiled with gcc optimization -O3
If you need to pass different CFLAGS, use something like this:
- CFLAGS="<gcc options>" $ME <installer options>
+ CFLAGS="<gcc options>" ${ME} <installer options>
For the installer to complete successfully, you will need
these packages installed:
- gcc make autoconf automake pkg-config zlib1g-dev
+ gcc make autoconf automake pkg-config zlib1g-dev (or zlib-devel)
+ uuid-dev (or libuuid-devel)
For the plugins, you will at least need:
- curl node
+ curl nodejs

apps.plugin needs privileges
Since you have installed netdata as a normal user, to have apps.plugin collect
all the needed data, you have to give it the access rights it needs, by running
-these commands:
+either of the following sets of commands:
- sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
- sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
+To run apps.plugin with escalated capabilities:
-The commands allow apps.plugin to run as root.
+ sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
