How to find out which sources are consuming the most RAM?

Chris Worner · Sep 19, 2019

Is there a way to find out which sources are consuming the most RAM on my server or which parts of websites are consuming too much RAM from my hosting server? I checked free -m in SSH and my server is just having 6% of free RAM, I need to free up my RAM, if no my websites can not run or will be downed. Can any one help me?

Hello @Chris Worner,
you can use htop to display the list of running process and their memory usage.

Most of the Big IT companies prefer using Nagios or Zabbix for monitoring the resources of thier web server. This helps them to check the traffic and the corresponding load on CPU. It also monitors the busy and idle threads and find out where improvements can be made. The stats provided about the load balancer will give you the exact idea of which part or resource of your website consumes major part.

top / htop : then press M to sort by memory consumption descending, will show you the top memory consuming process.

Try free Icinga2 to monitor services.
netdata(live) + graphite(archive) for system stats monitoring.

I second the top/htop way - nagyos/zabbix are too complicated for single-server config. OP just needs to check what's consuming his RAM.

In such cases of resource consumption, first option is to run a 'top -c' command to view the current dynamic process and their resource usage status.
Check the PID , %MEM , USER and COMMAND section of the result of the top process to see which process under which user is consuming more memory.

You can kill that process using the command:
~$ kill -9 <PID>
