Netdata β A Real-Time Performance Monitoring Tool for Linux Systems
Netdata is an enormously optimized Linux utility that presents real-time (per 2nd) efficiency monitoring for Linux techniques, applications, SNMP devices, etc. And shows full interactive charts that certainly renders all collected values over the web browser to investigate them. This article explains about how to find a real-time performance monitoring tool for Linux Systems.
Features
It monitors total and per Core CPU usage, interrupts, softirqs and frequency.
It monitors Memory, RAM, Swap and Kernel usage.
It monitors Disk I/O (per disk: bandwidth, operations, backlog, utilisation, etc).
It monitors Network interfaces including: bandwidth, packets, errors, drops, etc).
It monitors Netfilter / iptables Linux firewall connections, events, errors, etc.
It monitors processes (running, blocked, forks, active, etc).
It monitors system Applications with the process tree (CPU, memory, swap, disk reads/writes, threads, etc).
Apache and Nginx Status monitoring with mod_status.
MySQL database monitoring: queries, updates, locks, issues, threads, etc.
It monitors Postfix email server message queue.
Squid proxy server bandwidth and requests monitoring.
It monitors Hardware sensors (temperature, voltage, fans, power, humidity, etc).
It monitors SNMP devices.
Earlier than you installing netdata utility, be certain you’ve these basic construct atmosphere packages mounted on the system, if not install it. Use the next command to put in general construct environment-
$ sudo apt-get install zlib1g-dev gcc make git autoconf autogen automake pkg-config
The sample output should be like this –
Reading package lists... Done Building dependency tree Reading state information... Done gcc is already the newest version (4:5.3.1-1ubuntu1). gcc set to manually installed. make is already the newest version (4.1-6). make set to manually installed. pkg-config is already the newest version (0.29.1-0ubuntu1). pkg-config set to manually installed. The following additional packages will be installed: autogen-doc autotools-dev git-man liberror-perl libopts25 libopts25-dev libsigsegv2 m4 Suggested packages: autoconf-archive gnu-standards autoconf-doc libtool git-daemon-run | git-daemon-sysvinit git-doc git-el git-email git-gui gitk gitweb git-arch git-cvs git-mediawiki git-svn The following NEW packages will be installed: autoconf autogen autogen-doc automake autotools-dev git git-man liberror-perl libopts25 libopts25-dev libsigsegv2 m4 zlib1g-dev 0 upgraded, 13 newly installed, 0 to remove and 7 not upgraded.

Clone the netdata repository from git and run the following command to install netdata installer script to build it.
$ sudo git clone https://github.com/firehol/netdata.git --depth=1
The sample output should be like this-
Cloning into 'netdata'... remote: Counting objects: 253, done. remote: Compressing objects: 100% (241/241), done. remote: Total 253 (delta 10), reused 137 (delta 1), pack-reused 0 Receiving objects: 100% (253/253), 1.33 MiB | 471.00 KiB/s, done. Resolving deltas: 100% (10/10), done. Checking connectivity... done.
Now enter into netdata directory and install netdata installer, using following commands-
$ cd netdata $ sudo ./netdata-installer.sh
The sample output should be like this –

To stop the netdata, use the following command –
$ sudo killall netdata
You can also view the running configuration of netdata at any time, by using following url-
http://127.0.0.1:19999/netdata.conf
The sample output should be like this –
# NetData Configuration # You can uncomment and change any of the options below. # The value shown in the commented settings, is the default value. # global netdata configuration [global] # config directory = /etc/netdata # plugins directory = /usr/libexec/netdata/plugins.d # web files directory = /usr/share/netdata/web # cache directory = /var/cache/netdata # log directory = /var/log/netdata # host access prefix = # debug flags = 0x00000000 # memory deduplication (ksm) = yes # debug log = /var/log/netdata/debug.log # error log = /var/log/netdata/error.log # errors flood protection period = 1200 # errors to trigger flood protection = 200 # access log = /var/log/netdata/access.log # memory mode = save # hostname = linux # history = 3600 # update every = 1 # pthread stack size = 8388608 # run as user = netdata # web files owner = netdata # web files group = netdata # http port listen backlog = 100 # port = 19999 # ip version = any # bind socket to IP = * # disconnect idle web clients after seconds = 60 # enable web responses gzip compression = yes [plugins] # tc = yes # idlejitter = yes # proc = yes # cgroups = yes # checks = no # plugins directory = /usr/libexec/netdata/plugins.d # enable running new plugins = yes # check for new plugins every = 60 # apps = yes # charts.d = yes # node.d = yes # per plugin configuration [plugin:tc] # script to run to get tc values = /usr/libexec/netdata/plugins.d/tc-qos-helper.sh # enable new interfaces detected at runtime = yes # cleanup unused classes every = 60 [plugin:idlejitter] # loop time in ms = 20
To update the netdata, use the following commands –
# cd /path/to/netdata.git # git pull # ./netdata-installer.sh
Congratulations! Now, you know “Netdata – A Real-Time Performance Monitoring Tool for Linux Systems”. We’ll learn more about these types of commands in our next Linux post. Keep reading!
