Everything you need to know about Nagios plugin development can be found here:

https://nagios-plugins.org/doc/guidelines.html

If you have questions about plugin output, performance data, or thresholds we would be glad to help. However, please note that this forum is not the proper venue to learn PHP or other languages - for that you will need to find a tutorial or reference manual. We also cannot help each step of the way, but if you are running into issues with the plugin itself (and not the syntax of the language) we can assist.

You will want to read the section in the linked guide about Performance Data, which is specially-formatted output used to build graphs.

Assuming there are no typos in your code from that article, then this variable probably is not being set properly:

$used_space=chop(shell_exec("df -h / | grep -v Filesystem | awk '{print $5}'"));

It is possible that the df output is failing, or grep is not finding anything, or the input to awk is empty as a result. This is something you will need to troubleshoot however - assistance with any specific language is not in scope for this forum. We can assist with making sure your output and exit codes are proper, but the specifics of how those are determined are up to you.
