The Toolbox

Time:

dstat

Ever want a system monitoring tool that could replace quite a few of the existing one. Well dstat is that tool, it can replace vmstat, iostat, netstat, and ifstat. It not only can do what they do but also adds more functionality. This is a top notch tool for performance tuning, benchmarking, my personal favorite troubleshooting.

It will give you a real-time view of all your systems resources. Dstat will deliver all of that select-able detail in columns with magnitude unit of measure clearly indicated. This makes for less confusion which makes for less mistakes.

Your meant to view dstat’s output in real time. However it does provide for sending its output to a CSV file. You can then import this CSV file into your spreadsheet program of your choice. From there you can use the data to generate graphs.

Another great quality of dstat is that it is written entirely in python. This allows you you to extend dstat with your own custom modules.

Now for the installation. If you thought I was going to tell you how to install it you were wrong. If you don’t know how to install stuff on your system or servers maybe you should go back to Windows.

Now let’s get some stuff done!
In the simplest form you can just start it with:

dstat (you will get output like this)

[root@wackadoo.com]$ dstat
—-total-cpu-usage—- -dsk/total- -net/total- —paging– —system–
usr sys idl wai hiq siq| read writ| recv send| in out | int csw

# dstat -c –top-cpu -d –top-io –top-latency

[root@wackadoo.com]$ dstat -c –top-cpu -d –top-io –top-latency
—-total-cpu-usage—- -most-expensive- -dsk/total- —-most-expensive—- –highest-total–

7 1 92 0 0 0|php-fpm: pool2.5| 0 1440k|php-fpm: po1177k 537k|php-fpm: pool2395

Let’s look at what that means:
-c – shows the stats for the cpu(s)
–top-cpu – show what is using the most cpu at the given time
-d – show the disk i/o in Kb
–top-io – shows what process is using the most disk i/o
–top-latency – shows the process with the highest latency at the given time

To send the output to a csv file for later use we can issue the following command:

[NOTE: the –output needs to come before the flags]

# dstat –output dstat.csv -cdn

The flags in this command are
-c = which gives you cpu stats
-d = gives you stats on your hard drives
-n = shows you stats on your network connections

For a complete list of all options:

dstat –list

and if you want details you can read the man page

man dstat
