Tacking Number Of Users Logged In Over A Time Period - Database Design?
Nov 12, 2010
In our application, we store the most number of users online. We do this by tracking what page each user is on currently and upon login, delete users who have been inactive for X minutes and then take a count of the users online, overwriting the most number online if this is higher.
How can we change this to track the number of users online over a time period, so we can look at a line graph of the number of users online. I guess we'll need a cron to run every 1/2/5/10/20/30/60 minutes to track the number online? Then how would be store this data, the table would get very large. I would think the likes of Statcounter/Analytics would have a better way of storing this data.
I want to know what the members who are online at my site and I can identify them.Do you have an article that identifies registered online users like your site.
If I want to be able to have a table Consultant, which is the user and their personal information, and I want this user to be able to select their proficiency in a number of Programs (software) on a scale from 0-5 (zero being no experience whatsoever), how do I do this best?
I mean I could have a Consultant table with a one-to-many relationship to a Program table, and then have all the limited Programs availalbe loaded by an XML file or something, and for each Consultant associate all the Programs and their Levels of proficiency. But that seems very wrong and inefficient.
It seems to me I should have a table with all the (limited number of) Programs, and then by some sort of association between the two by Ids. But I can't get my head around how to do this. I'm thinking many-to-many... But first, is this correct? Secondly, how do I do this in an Entity Framework Model? I usually create my database code first, i.e. create the EF model, and then generate database from model. Will I get a junction table where I can add the Level field, because basically a Consultant HAS A Program with a Level, or actually a list of Programs each with a Level.

I want to redirect users when they reach a page in my web project. I want this to happen in page load after say 2 seconds.
I'm using this code on page load:
[Code]....
With this code, as soon as the page loads it redirects to that page. There are some text in this page that i want the user to see while the page is redirecting. What are my options? Should i use Timer? and tell it to redirect after two or three ticks?
I installed Rad Controls. Using that controls, I designed my application pages. At design time, the design is not visible. It shows the following error:
RadTabStrip1Failed to create designer 'Telerik.Web.UI.RadTabStrip, Telerik.Web.UI, Version=2010.1.415.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4'
I want that a specific asp.net control get refresh within a specified time period like there is datalist and i want that its content will be change after 10 sec.
Let's say we are building some public service that grabs the setup of a user (what server, user and pwd he wants to perform the call), logs in into that server and do some processing...
the process takes about 15 seconds to complete each user has a different setup (server/user/pwd), so the process needs to run against each one
if 1000 users tells the system to run the method at 1:00PM
How can I insure that the method is processed in the next 15 minutes?
What should be the correct approach to this little problem?
I'm thinking that I need to do something Asynchronously, and parallel processing could speed up things, maybe throttling the processes, maybe execute 100 calls per each 30 seconds?
I never did something like this and would love to get your feedback on ideas and future problems just to spend 100 hours of work and realize that I took a wrong road

My web site seems to be running quick. I have not deployed my web site yet, so I am the only one using it right now. The problem I have is if I am testing out the site and then I stop using it for a short period of time, when I come back the web site takes about 8-10 seconds to startup again. I did not rebuild the site I just simply stopped using it for a short period of time. It seems like after a short period of time I have to 'wake it up' again. Is this normal? How can I prevent this?
My environment is ASP.Net + IIS 7.0 + Windows Server 2008 + .Net 3.5. I am wondering whether the number of users online and number of active session are the same thing? The other question is, no matter whether they are the same, how to calculate them (i.e. for a given time, what is the number of users online, and related active number of sessions)?
We have implemented the ASP membership and roles..and we would like to display the users currently logged in and also display the number of users online so we can display that on the page. The list of users woudl only be available to our admins. BUt the number of users will show for everyone.
