Hi Orlando,
The agent running is running Java programs and Perl scripts. Java is
created for portability, using the "write once, debug everywhere" motto.
Problem with such portable solution is that they are using CPU, and a
lot of it. The same thing applies to my favorite monitoring tool,
Nagios. Nagios executes Perl scripts on the target databases and is,
consequently, using a lot of CPU. At one point in my career, I wrote a
monitoring tool in PHP, running under Apache web server. However, I am
no longer maintaining it. The only way to control the tool is to write
one yourself. These days, it's no longer that hard.
