Is there a way to read in status page and find a specific value and then check if that value is greater than a specific number? I checked the templates and I couldn't find anything.
There are multiple methods to do this through scripting. The general idea is that you can read the page source and search for a specific string/value, then report that value back to APM as a statistic. I'd recommend doing this in Python or Perl, but it can be done in just about any language. If you'd like to avoid adding additional packages to your poller (or wherever the script would be executed), you can use Bash or Powershell as well.
As thulsey suggested, it can be accomplished in several ways. I don't think there are any templates pre-built for this because it's likely to be very specific to the environment you are working in. For example, PowerShell you could use Invoke-WebRequest to make a call to the website to fetch the content, and -match to find the string you're looking for, and break out the value. What is your skill level for scripting?
