How to install "perf" monitoring tool?

On Ubuntu 14.04 I had to install three packages:

apt-get install linux-tools-common linux-tools-generic linux-tools-`uname -r`

The perf utility can be found in the linux-tools package.

Make sure you are installing this tool for the right Kernel release. If you just type:

sudo apt-get install linux-tools

It will install it for the latest Linux release in your machine and in case you are booting a previous version (say for stability reason), it will err. In my case it installed for .45 instead of .43 and I had to use the following command to install it:

sudo apt-get install linux-tools-3.2.0.43

You can find your Kernel release by typing : uname -r

To make sure it's working right you can try this: perf record /bin/ls

Just in case you are going to install Zoom tool, you need to have Perf installed for being able to use all its utilities.
