Monitoring SAP environment from portal

Question

Hello,
I’m a web developer and as I’m new to portal development I want to find out if there exists a program or way to monitor a SAP system from the portal.
I want to call up e.g. the dialog stats (st03n) for each day of the month and display a graph in the portal.
Once I can do that I want to call solution manager and determine the custom checks and create a graph/table for each of the checks.
E.g. If I need to check cpu performance (st04), canceled jobs (sm37) and short dumps (st22), then the page displays those either for the current day or I can choose to  display the month.
I know I have to use web dynPro IViews and Java and have been playing with JCo and jsp pages.
I also heard about JCA but have not gone into detail with that.
With JCo I can connect to a R3 system and call a BAPI function. As I found out there are thousands of them and no list, documentation or definition about them that I have found so far.
E.g.
import com.sap.mw.jco.*;
aConnection = JCO.createClient(SAP_CLIENT, USER_ID, PASSWORD, LANGUAGE, HOST_NAME, SYSTEM_NUMBER);
aConnection.connect();}
JCO.Function function = getFunction("BAPI_EMPLOYEE_CHECKPASSWORD");
JCO.ParameterList listParams = function.getImportParameterList();
listParams.setValue(username, "NUMBER");
listParams.setValue(password, "PASSWORD");
aConnection.execute(function);
I would appreciate it if someone can point me in the right direction.

Hello Nick,
I can create an IView for each transaction and display the gui frontend in the page, but that will be as if I work with the gui and not let me access or receive specific information.
It will also not be usefull to combine transactions in one page, or to create graphs from the information.
I want just the data that is stored in the database or created from the BAPI function I.e. variables or hashtables
