Is there A good strategy to Log the User activity on an ASP MVC App? (ActionFilters/ HTTPModules).
Something like last user activity (just like StackOverflow "Seen 23 mins ago"), and even what Pages and Controllers were used, and pushing even further what buttons or links were clicked.
I have ELMAH installed but as far as i know its just for Error Logging.
PD: Google Analytics is not an option.
You could try using a PostSharp aspect to perform the logging for you, it's multi-cast functionality might come in handy for something like that. If it's not an option, then a Module would probably be the easiest to implement (assuming you can get the required user information at that point in the pipeline).
@Rory's idea is excelent. PostSharp is just what you need for this, you might consider coupling it with ASP.net Health Monitoring
Action Filter Attributes are perfect for this, just put a call to [YourAttributeName] at the top of your controller (or if you have an Application Controller which your other controllers inherit from, you only need it once in your application).
For example:
namespace the_name_space
{
[Log]
public class ApplicationController : Controller
{
From this point onwards this attribute will be called before each action is run in your controller(s), you can also specify this on just an action by calling [Log] just before it in the same fashion.
To get the logging functionality which you require, you will most likely want to override OnResultExecuting and OnResultExecuted, both of which are pretty self explanatory.
An example of this may go a little like this:
public class LogAttribute : ActionFilterAttribute { protected DateTime start_time;
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
start_time = DateTime.Now;
}
public override void OnResultExecuted(ResultExecutedContext filterContext)
{
RouteData routeData = filterContext.RouteData;
TimeSpan duration = (DateTime.Now - start_time);
string Controller = (string)routeData.Values["controller"];
string Action = (string)routeData.Values["action"];
DateTime CreatedAt = DateTime.Now;
//Save all your required values, including user id and whatnot here.
//The duration variable will allow you to see expensive page loads on the controller and whatnot, very handy when clients complain about something being slow.
}
