<service-builder package-path="org.monitoring">
<namespace>PKS</namespace>
<entity name="Logindetails" uuid="true" local-service="true" remote-service="true">
<!-- PK fields -->

<column name="loginId" type="long" primary="true" id-type="identity"></column>

<finder return-type="Collection" name="Name_EmailAddress">
<finder-column name="emailAddress"></finder-column>
<finder-column name="username"></finder-column>
</finder>
</entity>

</service-builder>



Step3:
=====
Create 2 new Custom Classes in Src\ folder
1)  LoginDetails  

package com.test.hook;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import com.liferay.counter.service.CounterLocalServiceUtil;
import com.liferay.portal.kernel.events.Action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.monitoring.model.Logindetails;
import org.monitoring.model.impl.LogindetailsImpl;
import org.monitoring.service.LogindetailsLocalServiceUtil;

import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.exception.PortalException;
import com.liferay.portal.kernel.exception.SystemException;
import com.liferay.portal.model.User;
import com.liferay.portal.util.PortalUtil;

public class LoginDetails extends Action {

public LoginDetails() {
super();
}
public void run(HttpServletRequest request, HttpServletResponse response) throws ActionException {

/* String date = null;
*/ Date date = new Date();
/*SimpleDateFormat formatter;
formatter = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss Z");

date = formatter.format(date1);
System.out.println("+++++ Current Logintime +++++"+date);
*/

System.out.println("===Getting Current Login Time=== :"+date);

      try {
      User currentUser;
      long userId;
      String emailaddress;
      String username;
     
      try {
     
currentUser = PortalUtil.getUser(request);
System.out.println("Current Username:   "+currentUser);
userId = currentUser.getUserId();
System.out.println("UserId:   "+userId);
    emailaddress = currentUser.getEmailAddress();
    username = currentUser.getFirstName();
   
     String ipAddress = PortalUtil.getOriginalServletRequest(request).getRemoteAddr();
         System.out.println("====Your IP Address Is === :"+ipAddress);
   
        long loginId = CounterLocalServiceUtil.increment(Logindetails.class.getName());
Logindetails logindetails = new LogindetailsImpl();
logindetails.setLoginId(loginId);
logindetails.setUserId(userId);
logindetails.setUsername(username);
logindetails.setLoginIp(ipAddress);
logindetails.setEmailAddress(emailaddress);
System.out.println("===Got Current Login Time===:"+date);
logindetails.setLoginDate(date);

LogindetailsLocalServiceUtil.addLogindetails(logindetails);
HttpSession session = request.getSession();
        session.setAttribute("loginID",logindetails.getLoginId());
        System.out.println("before: "+logindetails.getLoginId());
             
} catch (PortalException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
   
} catch (SystemException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
       

}

}

2) LogoutDetails  :
package com.test.hook;
import java.util.Date;

import com.liferay.portal.kernel.events.Action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.monitoring.model.Logindetails;
import org.monitoring.service.LogindetailsLocalServiceUtil;
import com.liferay.portal.kernel.events.ActionException;
import com.liferay.portal.kernel.exception.PortalException;
import com.liferay.portal.kernel.exception.SystemException;

public class LogoutDetails extends Action {

public MonitoringLogout() {
super();
}

public void run(HttpServletRequest request, HttpServletResponse response) throws ActionException {

System.out.println("monitoring portlet created");
System.out.println("===Getting Current Logout Time === :"+new Date());

Date date;
date = new Date();
   
try {        
    try {

       HttpSession session = request.getSession();
     
       System.out.println("Object o   :"+session);
     
        Long  sessiId =(Long)session.getAttribute("loginID");
        System.out.println("after: "+sessiId);
        Logindetails login = LogindetailsLocalServiceUtil.getLogindetails(sessiId);
        login.setLogoutDate(date);
        LogindetailsLocalServiceUtil.updateLogindetails(login);
} catch (PortalException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
   
} catch (SystemException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

Step4 :
=====

login.events.post=com.test.hook.LoginDetails
logout.events.pre=com.test.hook.LogoutDetails

Step 5:
=====
