Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have running some servers on rackspace and I want to know if there is a web application like linode-graphs as you can see in the image ?

I want to see graphs of server activities like:

  1. ram
  2. cpu
  3. network
  4. io
  5. ...etc

thanks for your help :)

linode graphs

Munin is just what you are asking for. It consists of two parts; munin-master and munin-node. If you just have one host you can install both packages and munin will collect a set of default statistics, draw graphs and create a simple HTML dashboard for you. If you have several machines you want to monitor you only need one munin-master, but you will need munin-node on all hosts you want to gather statistics from.

About munin

Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?" problems. It is designed to be very plug and play. A default installation provides a lot of graphs with almost no work.

Installing munin

Ubuntu / Debian

apt-get install munin munin-node

RHEL / CentOS

yum install munin.noarch munin-node.noarch

Munin is definitely an opinion. Another solution that i like is Observium. Take a look at Observium here. You will get everything you need including the same graphing engine (rrdtool) in this case. I find the interface pretty easy to navigate. The only catch is you can only grab it via SVN and there are some dependencies that you'll need to address.
