Memory and Database Monitoring

Hi,

We have recently implemented lpar2rrd tool to monitor CPU usage in our company but now they are are asking if it is possible to monitor Database and memory usage and have it output the data on a graph as well. The memory part I know it is possible I am just not sure how to implement it. Databases I'm at a loss. Complete different language to me.

Anyone have any advise on how i can complete this?

Maybe create another webpage and link it to lpar2rrd's page for database and individual Mem Usaage?

Seems strange to post a question about "monitoring a database" without posting any details about the "database".
