Previously we talked about a good tool named GoAccess for traffic analysis. netdata is similar quality good tool which provides a web ui for monitoring, log analysis and other sysadmin works. Here is how to install netdata on Ubuntu 16.04 running Apache2 on single cloud server. Installing on server running Apache2 is just easy. There is huge documentations on netdata’s official Github repo’s Wiki. netdata will run on TCP port number 19999. So if you are using iptables or any firewall, you need to open the port. Test it on dev server first, get used around how to tweak it, configure it; thereafter configure to add remote servers.
How To Install netdata on Ubuntu 16.04
First we ran these commands to install any needed missing tool :
1 2 | sudo apt-get install zlib1g-dev uuid-dev libmnl-dev gcc make autoconf autoconf-archive autogen automake pkg-config curl sudo apt-get install python python-yaml python-mysqldb python-psycopg2 nodejs lm-sensors netcat |
We installed in this way following their official guide :
---
1 2 | curl https://my-netdata.io/kickstart-static64.sh >/tmp/kickstart-static64.sh sh /tmp/kickstart-static64.sh |
Then got this response :
