I used the following below to create a widget in Panic’s Status Board.
To start, we’ll need to configure
top to show more than one core. To setup
top to reveal all CPU’s by default, login w/ ssh to your server and run the following:
1 reveals all cores.
shift+W saves the current screen as default. Exit
top once complete w/
Next we’ll add a cronjob to make
top output to a text file every minute. Launch the crontab editor
add at the bottom:
‘/…/’ is a real path to somewhere on your server. I recommend keeping it 1-below your public
/httpdocs/ directory so the world can access it but your scripts can. Then to save changes:
ZZ. You can double check that it’s installed with
should show your new addition. That’s it. Now every minute
top will write to your
Now on to scripting.
We need to use some PHP to import and parse the
top output data, and jQuery to reload the import/parse portions of the page for a continual update.
Make a php file, and add the following JS to the head:
http://…/this_file.php is the URI of your current file.
/var/www/…/top.txt is the path to your
top output, and
16 is the number of cores you have on your server (if unsure, count them in the
top.txt output). The “load time %” is a percentage out of 5 seconds.
0% being 0 load time,
100% being 5 second load time.
Once this is setup, done, and working you’ll now have a file that continually refreshes your servers output. From there you can use tools like gauge.js to animate some gauges, or create your own.
