Linux – More in depth TOP command

central-processing-unitlinuxPHPtop

I recently came across a screenshot that looks to be using the "top" command, but it is showing a lot more in-depth info in terms of CPU usage:

enter image description here

The program shows detail down to which plugin in WordPress is taking up all the resources. How is this possible?

The tool used is htop. And advanced top.

In htop you could scroll, so it is possible to show the full process name, with php scripts, depending on your webserver

You can set COLUMNS environment variable to a large value. For example, to set it just for top invocation:

$ COLUMNS=1000 top -c -b -n 1 > top.log

At least it works in bash 4.0.33 on Ubuntu 9.10.

Linux – High MySQL CPU usage but no heavy query

Two things come to mind here :

Observation 1

When MySQL causes a constatntly fluctuating CPU, I would first check what kind of installation of MySQL was performed. MySQL RPMs usually contain binaries that have been optimized for specific platforms. On the other hand, MySQL binaries that have been compiled from source tend not to be lean and mean. Such binaries could be bloated and not optimized at compile time to take advantage of memory.

Observation 2

If the InnoDB Buffer Pool (innodb_buffer_pool_size) or the MyISAM Key Cache (key_buffer_size) is underconfigured or overconfigured, you could potentially be spending time clean out caches without the presence of new queries.
