Editor to share with you how to use Linux performance real-time monitoring tool Netdata. I hope you will get something after reading this article. Let's discuss it together.

Netdata is a real-time Linux performance monitoring tool. Display the real-time running status of the system and applications in a visual way of web (including cpu, memory, hard disk input / output, network and other linux performance data).

Install with script:

# basic installation (for all Linux systems) $bash # or install from scratch (install all dependent packages) $bash

Or install it through the newspaper manager:

Arch Linux (sudo pacman-S netdata) Alpine Linux (sudo apk add netdata) Debian Linux (sudo apt-get install netdata) Gentoo Linux (sudo emerge-ask netdata) OpenSUSE (sudo zypper install netdata) Solus Linux (sudo eopkg install netdata) Ubuntu Linux > = 18.04 (sudo apt install netdata) MacOS (brew install netdata)

When prompted, netdata installs the files in these locations:

Once installed, you can directly open the browser: localhost:19999 sees a cool screen (the web page is long and shows a lot of data).

After installation, Netdata runs primarily as a service.

Switch control:

# Startup: the location varies according to the system. It is recommended to add the-D parameter to run in the foreground. Do not run $sudo netdata-D$ or $sudo / usr/sbin/netdata-D# or (on Mac) $sudo / usr/local/sbin/netdata-D# off (there are many ways, often only one works) $sudo killall netdata# or $sudo pkill-9 netdata# or $sudo service netdata stop# or $sudo / etc/init.d/netdata stop# or $sudo systemctl stop netdata

Uninstall:

# find the location of the uninstall script (my / usr/src/netdata.git) where whereis netdata.git# enters cd / usr/src/netdata.git# and start uninstalling yes | sudo. / netdata-uninstaller.sh-- force# deletes other legacy information sudo userdel netdatasudo groupdel netdatasudo gpasswd-d netdata admsudo gpasswd-d netdata proxy

Uninstall other installed software:

Yes | experience of using sudo apt-get purge ntop snapd

It's really cool to browse large and accurate system information on the web. But! Seriously affect the speed of the server! Long-term consumption of 10% memory and high CPU. And also found that Netdata in order to monitor, but also installed a lot of other software, running in the background for a long time. Even serious enough to affect the delay of SSH, ssh entered the typing response is very slow. So there's no way to uninstall it.

After uninstalling the Netdata software itself and other memory-intensive CPU background resident software installed, the server was restarted and the previous speed was restored.
