Tracking errors in real-time / production web applications

Question

I currently work for a company that has many custom applications created internally. There are currently no standards for many things. I would like to implement a way to record / track errors that occur in these programs (most of them are asp.net).

I am currently thinking of handling this in Global.asax in an application error method. First try to save the information in the error / tracking log database, and if that fails, try sending an email.

What type of information is most useful for receiving error messages and other application variables (page, username, etc.).

I am currently thinking of using two tables, one for general information about errors and applications, and the second for information about exceptions. It will be a one-to-many relationship to pass internal Exceptions that may come from one application-level exception.

I’m sure that I don’t have enough details and would like to hear your strategy for solving this problem.

Answer 1

Jeff Atwood wrote a great exception handler that you should look at CodeProject

I tried to collect as much information as possible. Stack Information Session Information Error Location

I would also install a web service that applications access to store exception information on your system.

Answer 10

It is a very good idea to log in to a custom event log on the server, as well as for any other logging and notification. If an error occurs due to a problem with the infrastructure, the same problem can also cause the error handler to send e-mail or save it to the database.
