Hi,
You can not check the online concurrent users using out of the box functionality, you might need to use session variables (not recommended as CRM itself is designed stateless) into the custom hosted asp.net web pages called into an IFrame
or Sitemap to maintain the session count, else you can use CRM plugin or as Feridun Kadir mentioned you can use IIS to dump the user request time in, you may also refer:
The solution in the following links is available for Dynamics CRM 4.0 via IIS (http://blogs.msdn.com/b/crm/archive/2009/04/08/crm-usage-reporting-unleashed.aspx)
, should work with CRM 2011. Its only supports On-Premise (company hosted CRM environment) and also not support IFD/Claim based authentication.
You can use the solution mentioned in the following blog post for On-Premise IFD based authentication http://a33ik.blogspot.com/2010/04/crm-usage-report.html, it is developed
for CRM 4.0, you may have to convert it to CRM 2011. If planning to use this solution in CRM 2011 then you may also try register CRM 4.0 plugin in CRM 2011 as mentioned in the following post: http://worldofdynamics.blogspot.com/2011/08/dynamics-crm-2011-registering-crm-40.html
