Event Logs in asp.net for portal and server

Question

Hi all...

Once again... In trouble....

Please guide me... How to build event logs in any asp.net c# website ??

Requirement -
1. If a user opens a portal, then the system must capture the page name (index.aspx), the user name, and current time. - Done.

2. If user clicks on any button (say btn_Save, btn_Search), then system much capture the pagename, username, button-id, button-text that was clicked, and time.

In short... How to create such event logs for asp.net website / portals ?

Currently there are 20 web pages in the portal.

Do I need to use System.Diagnostics namespace??
--------------------------------------
Other Point -
I have recently faced an incident.
I had uploaded my published files on the iis server.(Remote Desktop Connection)
The system was running smoothly.
But... One other person from other team entered the server and changed the physical path of my portal.
By this, I got many complaints from the users that the site is not working.
-------
Is there any way in which we can find out who enters the server and make such changes ??
-----
Is there any way in which we can capture the username/windows name and find the activities done on server ??
--
Please guide.

Thank you all in advance...

Hello For CPU Performance you use PerformanceCounter Class See Links :- https://msdn.microsoft.com/en-us/library/system.diagnostics.performancecounter.aspx http://stackoverflow.com/questions/4679962/what-is-the-correct-performance-counter-to-get-cpu-and-memory-usage-of-a-process

Hi.. System.DIagonstics namespace has Stopwatch... This calculates time in milliseconds. But What to do if I want to calculate machine time CPU Time get resources used by CPU time taken by each resource etc. In Short How to calculate CPU Time ???

Jitendra Kumar · Answer

Hello Use StopWatch to code optimization of function or btn click. See Links : http://www.dotnetperls.com/stopwatch Regarding parameter : It Depends on requirement. I have never seen guideline of parameter but in my exp function that takes more than four or five parameters creates some problems like Code readebility. In Any Condition you have so many parameters it is better to pass an object as a single parameter and have the parameters as properties. Like this : Public stuct fncPara { Public string Name; Public string Ip; Public string ControlId; Public string ControlName; Public string BtnEvent; } Public void fncAdd(fncPara objPara) { } at least is easier to read. Regarding Performance or optimization I have no idea.

Thanks a ton... I am trying this method... PLease let me know how to calculate time taken for code in button_click to execute ?? button_click() { //10 lines of c# Code } -- How many seconds/ milli seconds are required to execute these 10 lines. ---- There are 8 methods in my application in which there are more parameters(more than 9). The portal was developed in 2012 (don't know by whom). I know that more parameters in a method is not a good programming practice. I want to know - 1. Time taken to execute a method with 1 parameter. 2. Time taken to execute a method with 9 and more parameters. --- Difference between less and more number of parameters in a method... Please Guide... Thanks in advance..

Hello Ridhi In Function you write code for insert data in database like this :- public static void CreatErrorLog(string Pagename string ctrlname string ctrlid string ipaddress string txt) { MySqlConnection conn = new MySqlConnection(ConfigurationManager.ConnectionStrings[ConnectionString].ConnectionString); conn.Open(); MySqlCommand cmd = new MySqlCommand(Insert into student (pagenamectrlnamectrlidipaddress txt) values (pagenamectrlnamectrlidipaddress txt) conn); } And Now call this function with value. Get Page page Name -- Path.GetFileNameWithoutExtension(Request.Path); Button Name in get in btnclick event For IP Address See links :- http://stackoverflow.com/questions/19285957/how-to-get-public-ip-address-of-a-user-in-c-sharp http://www.aspsnippets.com/Articles/How-to-get-IP-Address-of-Visitors-Machine-in-ASP.Net.aspx Like CreatErrorLog(Path.GetFileNameWithoutExtension(Request.Path) buttonname id ip txt); If any problem or query plz revert me.

Hi... I need all these things in database (sql server). Example - ID UserID PageName ControlName ControlID ControlText IPAddress Event Fired Date 1 101 Home.aspx Button btn_Save Save 1.1.1.1. Button_Click 22-03-2014 2 102 Home.aspx Button btn_Search Search 1.1.2.3 Button_Click 22-03-2014 3 101 ErrorPage.aspx Textbox txt_Search 1.1.1.1 22-03-2014 In row-3 the user is working on TextBox. Hence its current value is null unless the user types in. ----------- How do I achieve this ??

Hey Ridhi Create log file using Function like this :- public static void CreatErrorLog(string strMsg) { string strLogFilePath = null; if (System.IO.Directory.Exists(d:\ErrorLog) == false) { System.IO.DirectoryInfo dirELogs = default(System.IO.DirectoryInfo); dirELogs = System.IO.Directory.CreateDirectory(d:\ErrorLog); } strLogFilePath = d:\ErrorLog\ErrorLog_; FileStream fs1 = default(FileStream); StreamWriter sw = default(StreamWriter); DataSet dsFile = new DataSet(); try { if (System.IO.File.Exists(strLogFilePath) == false) { fs1 = new FileStream(strLogFilePath FileMode.Create); sw = new StreamWriter(fs1); sw.WriteLine(msg.Trim()); sw.WriteLine(-----------------------); sw.Close(); fs1.Close(); } else { fs1 = new FileStream(strLogFilePath FileMode.Append FileAccess.Write); sw = new StreamWriter(fs1); sw.WriteLine(msg.Trim()); sw.WriteLine(-----------------------); sw.Close(); fs1.Close(); } } } And Now call this function with value whatever you want to show in log. Like CreatErrorLog(hello) CreatErrorLog(Page.Name + btn.Name) If any problem or query plz revert me.
