Application to chart the free memory available on a server at regular intervals.
##How this works
A cron job is set up on your server like this:
00 06 * * * cd /home/web/memfree && sh memfree.sh
You can change the options to have it run however times you want of course. Your paths may differ as well.
Memfree.sh is very simple:
#!/bin/bash
cat /proc/meminfo | grep MemFree > /home/web/memfree/perfprofile/$DATE-$TIME.txt
This simply dumps the current free memory info into a text file.
The next cron job will call /jogs/checklog.php which will see if there are any new log files added, and if they are they'll be stuffed into a mysql database.
When you bring up the index of the website you'll see a chart rendered by D3 that looks like this:
I'll be adding some features to this such as realtime values as well.
