[Xymon] Creating Java Monitor for Xymon

[Foster Patch]

Hello, I have created a Java Program that will pull a date from a stored procedure in a SQL Server, which then is compared to the current date, and will alarm red if it is past the threshold. Thus far, I have developed the code independent of Xymon, but now plan on implementing it since it is functioning properly. Below is my java code. Instead of printing out "Uh oh" if the date is older than 2 hours, I would like to make it alarm on the servers page. I don't know where to begin from here, and any suggestions or pointers in the right direction would be great. Additionally, any examples of using Java as a monitor in Xymon would be very beneficial. I plan on storing this in \ext\trunk\monitor.d\120.

package connect;

import java.sql.DriverManager;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;


public class Sqlselection {

        public static void main(String[] args) throws SQLException, ClassNotFoundException {
                CallableStatement callableStatement = null;


                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                Connection conn = DriverManager.getConnection("jdbc:sqlserver://sqldev-v02.accu.accuwx.com;database=analysis_summary;integratedSecurity=true;");
                String getCall = "{call proc_Return_Latest_AirQuality_DateTime}";

                callableStatement = conn.prepareCall(getCall);

                ResultSet rs = callableStatement.executeQuery();

                while (rs.next()) {
                        String delims = "[.]+";
                        String seconddelim = "[- :]+";
                                String columnValue = rs.getString(1);
                                String[] tokens = columnValue.split(delims);

                                String checkTime[] = tokens[0].split(seconddelim);

                                int year = Integer.parseInt(checkTime[0]);
                                int month = Integer.parseInt(checkTime[1]);
                                int day = Integer.parseInt(checkTime[2]);
                                int hour = Integer.parseInt(checkTime[3]);
                                int minute = Integer.parseInt(checkTime[4]);
                                int second = Integer.parseInt(checkTime[5]);

                                Calendar cal = Calendar.getInstance();
                                Date todayDate = new Date();

                                todayDate = cal.getTime();


                                Date checkDate = new Date();
                                checkDate.setYear(year-1900);
                                checkDate.setMonth(month);
                                checkDate.setDate(day);
                                checkDate.setHours(hour);
                                checkDate.setMinutes(minute);
                                checkDate.setSeconds(second);

                                todayDate.setHours(todayDate.getHours()-2);

                                if(checkDate.before(todayDate)){
                                        System.out.println("UH OH");
                                }
                                else if(checkDate.after(todayDate)){
                                        System.out.println("yep");
                                }
                        }
        }
}
