Install netdata monitoring in CentOS 7

netdata became a great tool for admins to monitor in real time their servers!
At first it was just an additional not mandatory tool to check what’s going on with the servers for the last hour or so, but it evolved to really handy and informative monitoring server tracking every seconds what is going on with the server and server’s most used services like database, web, application service.
Today in version 1.9 (this installation howto is for netdata 1.9) it could track activity at least of this services:

apache          hddtemp          postgres
beanstalk       haproxy          rabbitmq
ceph            isc_dhcpd        retroshare
bind_rndc       ipfs             redis
couchdb         memcached        sensors
chrony          mdstat           samba
cpufreq         mongodb          squid
dns_query_time  nginx            springboot
dnsdist         mysql            smartd_log
elasticsearch   nsd              tomcat
dovecot         nginx_plus       web_log
exim            ovpn_status_log  varnish
example         ntpd             fronius
freeradius      postfix          named
fail2ban        phpfpm           snmp
go_expvar       powerdns         stiebeleltron

And some of these plugins support multiple programs and services, for example web_log supports the access/error logs of the major web servers at the moment.

The installation is really simple netdata includes a script to facilitate the installation process.
Here are the minimal steps to install this great software:

STEP 1) Install dependencies, because will pull it from the official repository we also need git command

yum install -y git gcc make autoconf automake pkgconfig zlib-devel libuuid-devel curl nodejs freeipmi freeipmi-devel elfutils-libelf cmake openssl-devel libuv-devel

As you can see there is a nodejs packet, which depends on additional repository (you could skip this, just the modules, which depends on nodejs won’t work, as if now only the plugins using nodejs are located in “/etc/netdata/node.d/” and they are not so many).

yum -y install epel-release
yum -y install nodejs

STEP 2) Clone the netdata repository

cd
git clone https://github.com/firehol/netdata

STEP 3) Instal netdata

cd netdata
CFLAGS="-march=native -O2 -msse3 -fomit-frame-pointer -pipe" ./netdata-installer.sh --install /usr/local/netdata

Install the netdata software in a separate directory and if you clean the system, just delete this directory. The example above uses

/usr/local/netdata

all files will be installed there.
As you can see the installation output the path of your files

   - the daemon     at /usr/local/netdata/netdata/usr/sbin/netdata
   - config files   in /usr/local/netdata/netdata/etc/netdata
   - web files      in /usr/local/netdata/netdata/usr/share/netdata
   - plugins        in /usr/local/netdata/netdata/usr/libexec/netdata
   - cache files    in /usr/local/netdata/netdata/var/cache/netdata
   - db files       in /usr/local/netdata/netdata/var/lib/netdata
   - log files      in /usr/local/netdata/netdata/var/log/netdata
   - pid file       at /usr/local/netdata/netdata/var/run/netdata.pid
   - logrotate file at /etc/logrotate.d/netdata

STEP 4) USE firewall and open the port 19999 of your server to check e able to load the monitoring page

firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="<YOURIP>" port protocol="tcp" port="19999" accept"
firewall-cmd --add-rich-rule="rule family="ipv4" source address="<YOURIP>" port protocol="tcp" port="19999" accept"

Because firewalld is the default firewall under CentOS 7 we used it ot show you how to let your IP access netdata web – replace with your current trusted IP.

* The installation process creates start/stop unit files for systemd and tells you how to update it (even you can run it automatically in a cron job)

To stop netdata run:
  systemctl stop netdata
To start netdata run:
  systemctl start netdata
 
Uninstall script generated: ./netdata-uninstaller.sh
Update script generated   : ./netdata-updater.sh
 
netdata-updater.sh can work from cron. It will trigger an email from cron
only if it fails (it does not print anything when it can update netdata).
Run this to automatically check and install netdata updates once per day:
 
sudo ln -s /root/netdata/netdata-updater.sh /etc/cron.daily/netdata-updater

* Here is the output of an installation help menu – it also hints the dependencies it may need:

[root@srv.local netdata]# ./netdata-installer.sh --help

./netdata-installer.sh <installer options>

Valid <installer options> are:

   --install /PATH/TO/INSTALL

        If you give: --install /opt
        netdata will be installed in /opt/netdata

   --dont-start-it

        Do not (re)start netdata.
        Just install it.

   --dont-wait

        Do not wait for the user to press ENTER.
        Start immediately building it.

   --auto-update | -u

        Install netdata-updater to cron,
        to update netdata automatically once per day
        (can only be done for installations from git)

   --enable-plugin-freeipmi
   --disable-plugin-freeipmi

        Enable/disable the FreeIPMI plugin.
        Default: enable it when libipmimonitoring is available.

   --enable-plugin-nfacct
   --disable-plugin-nfacct

        Enable/disable the nfacct plugin.
        Default: enable it when libmnl and libnetfilter_acct are available.

   --enable-lto
   --disable-lto

        Enable/disable Link-Time-Optimization
        Default: enabled

   --zlib-is-really-here
   --libs-are-really-here

        If you get errors about missing zlib,
        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 -O2
If you need to pass different CFLAGS, use something like this:

  CFLAGS="<gcc options>" ./netdata-installer.sh <installer options>

For the installer to complete successfully, you will need
these packages installed:

   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, bash v4+, python v2 or v3, node.js

* netdata in action

main menu
All real-time monitoring plugins, System Overview opened

main menu
Memory details

main menu
PHP-FPM local details

* And here is the output of an installation process:

[root@lsrv3 netdata]# CFLAGS="-march=native -O2 -msse3 -fomit-frame-pointer -pipe" ./netdata-installer.sh --install /usr/local/netdata

  You are about to build and install netdata to your system.

  It will be installed at these locations:

   - the daemon     at /usr/local/netdata/netdata/usr/sbin/netdata
   - config files   in /usr/local/netdata/netdata/etc/netdata
   - web files      in /usr/local/netdata/netdata/usr/share/netdata
   - plugins        in /usr/local/netdata/netdata/usr/libexec/netdata
   - cache files    in /usr/local/netdata/netdata/var/cache/netdata
   - db files       in /usr/local/netdata/netdata/var/lib/netdata
   - log files      in /usr/local/netdata/netdata/var/log/netdata
   - pid file       at /usr/local/netdata/netdata/var/run/netdata.pid
   - logrotate file at /etc/logrotate.d/netdata

  This installer allows you to change the installation path.
  Press Control-C and run the same command with --help for help.

netdata by default listens on all IPs on port 19999,
so you can access it with:

  http://this.machine.ip:19999/

To stop netdata run:

  systemctl stop netdata

To start netdata run:

  systemctl start netdata


Uninstall script generated: ./netdata-uninstaller.sh
Update script generated   : ./netdata-updater.sh

netdata-updater.sh can work from cron. It will trigger an email from cron
only if it fails (it does not print anything when it can update netdata).
Run this to automatically check and install netdata updates once per day:

sudo ln -s /root/netdata/netdata-updater.sh /etc/cron.daily/netdata-updater

 --- We are done! ---
