I'm interested in using ELMAH but need to configure it programmatically. We have existing infrastructure for determining connection strings and the like, and can't code them into Web.Config.How do I go about using ELMAH in this case?
View 1 RepliesI'd like to configure ELMAH for an ASP.NET MVC site entirely in code. This includes registering the module, setting the logging provider and settings, and filtering exceptions.The only part I've managed to do so far is filter exceptions. Has anyone else figured out how to do this? I'd really like to avoid cluttering up my config file with settings that won't ever change.
View 2 RepliesI would like to configure ELMAH to my website, so I can log the error message on my SQL Server Database.
I have tried and put all the required configuration on the web.config file and copied the files to bin folder but no luck nothing is getting logged on my database.
Let me know if you require me to upload my web.config file.
The article link as below.

I'm following this blog post about setting up ELMAH with MVC: [URL] I've only done part 1. Everything works correctly if I simply go to the Home controller, and then cause an error. I can view /elmah.axd as well, and my errors are logging in the database correctly.
However, I've added an area to my application named Admin. If I navigate to /Admin, I receive the following error:
System.MissingMethodException: No parameterless constructor defined for this object.
public override IController CreateController(RequestContext requestContext, string controllerName)
{
var controller = base.CreateController(requestContext, controllerName); //Error here
var c = controller as Controller;
I'm assuming this has something to do with my Area.
EDIT for jfar:
For instance, I have an Employees controller in my Admin area:
public class EmployeesController : Controller
{
private IEmployeesRepository employeesRepository;
public EmployeesController(IEmployeesRepository employeesRepository)
{
this.employeesRepository = employeesRepository;
}
//...
}
I am trying to setup elmah for asp.net 1.1 application.i have following entry in my web.config
<httpHandlers>
<add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
</httpHandlers>
[code]...
I have ELMAH setup on my production server and it has done a fantastic job of letting me know about any niggles - as well as any creative SQL injection!I've decided to introduce URl Rewriting and went for http://www.urlrewriting.net/ in the end. It was nice and easy to setup and it's doing exactly what I want with the customer-facing site.The problem is ELMAH. Because I've set the urlrewritingnet node in my config like so:
<urlrewritingnet
rewriteOnlyVirtualUrls="true"
contextItemsPrefix="QueryString"
[code]...
There used to be an article at ELMAHs docs site that contained this information, but it seems to have been removed. I think it's as simple as setting a configuration setting in the section, but I haven't a clue what it isCan anyone take a few seconds and drop the configuration setting here?
View 1 RepliesI am using Elmah in one of our production deployments and would like to secure the module to the local network only and not expose it to the public. I am aware of the remote logging option that can be turned off and also asp.net authorization, however I am interested to know if there is any support in Elmah's configuration to bind to a secondary NIC/network card which only faces the internal network ?
View 1 RepliesI'm using ELMAH to handle the exceptions in my ASP.Net MVC project. I would like to use it to log errors like database connection timeout, query connection timeout and others. Is this possible with ELMAH?
View 2 RepliesI've just starting looking at a site in place at work. They're using Elmah to log errors.It seems to be logging fine, but in the web interface, when I tell Elmah to show me 100 errors per page, it only shows the most recent 15.Then when I click on "Download Log" I only get shown 15 errors in the CSV.Anyone know how I can configure it to keep all the errors?Or can someone point me to some docs on how to do this?

View 2 RepliesI'm using the suggestion from this question: How to get ELMAH to work with ASP.NET MVC [HandleError] attribute?I used Aziz's second code sample.I ran the debugger to see what happens when an error occurs. The main function in the HandleErrorAttribute class is:
public override void OnException(ExceptionContext context)
{
base.OnException(context);

I spawn a thread on Application_Start and would like to log exceptions. There is not Context/HttpContext/HttpContext.Current, so how might i get it to log?ATM it does not catch any exception in my threads and if i write ErrorSignal.FromCurrentContext().Raise(ex); i get an error about context cannot be null.Maybe i can create a dummy HttpContext but somehow i dont think that will work well.-edit- i tried ErrorSignal.Get(new HttpApplication()).Raise(ex); and it doesnt seem to pick up that exception.
View 2 RepliesSo, have an ASP 3.5 site built using ELMAH.
It runs fine under IIS 5.1, I can see all the error pages, etc.
Set up the site on another machine running IIS 7.5.
Now when I go to my /admin/elmah.axd page, i see a 404 error from IIS 7.5.
I was going to use ELMAH for our ultimate automatic error logging but recently realized that ASP.NET Health Monitoring does a same work (perhaps). Now I want to know (please) if they are alternatives of each other just like log4net and entlib?
View 3 RepliesI'm using Elmah with ASP.NET and wondering how I would add custom data, such as a session variable, to an unhandled exception email.I've tried several handlers in the Global.asax file but can't seem to find the right one.
View 2 RepliesIs there a way to globally handle exceptions in regular ASP.NET Web Service (asmx) using ELMAH like we do it in ASP.NET web site ?
View 2 RepliesThis question builds on the following question:How to get Elmah working with ASP.NET and IIS 5.1 URL RoutingThe solution suggested there worked, as long as elmah.axd is off of the root of the site. What if you want to secure the site as blogged here:Securely Implement ELMAH For Plug And Play Error Logging?Moving elmah.axd to /admin/elmah.axd breaks the Fix IIS 5x Wildcard Mapping Module.My workaround was just to secure "elmah.axd" instead of "admin," like:
<location path="elmah.axd">
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</location>
Although this works, I feel that there's got to be a more elegant solution.
I want to write this
<elmah>
<errorlog type="Elmah.XmlFilerErrorLog, Elmah" logPath="~/App_Data" />
</elmah>
or
<elmah>
<errorLog type="Elmah.SQLiteErrorLog, Elmah" logPath="~/App_Data" />
</elmah>
however every place i tried putting this tag in i get an Unrecognized configuration section elmah. error. I found this question [URL] however i tried that (solution at the bottom of the question) and still get the error. Where do i put this? i found the issue. I didnt set <sectionGroup name="elmah"> properly. I couldnt find it online then remembered the demo had sqlite logging and i checked the demo config for clues.
OK, apparently related questions dont seem to address this directly. An exception reaches Elmah, maybe a repository cant reach a database, but then neither can Elmah reach that database. Even if they target different servers, maybe its a network problem.
Is there a way to configure fallback logs for Elmah for cases like this, e.g. a text file, message queue, email, sms, etc? If so, where do I start looking to do this, excpt for now the Elmah source code.
i have a problem where i have an exception being thrown that i am capturing in global asax. As part of this exception handling i redirect the user to a specific page because of this exception.
i also have ELMAH error handling with the email module plugged in. I do not want to receive emails for this exception. I also don't want to add this type of exception to ELMAHs ignore list, in case i want to do granular work around the exception (ie, only if it matches certain properties, happens on certain pages)
i want to:
write an Application_OnError that redirects a user to a page (i know how to do this part, more for procedure i've left it here) In the Application_OnError stop ELMAH fromrecieving this error after i've caught it
i am currently calling Server.ClearError() inside my App_OnError method, but am still receiving these emails....
Does anyone know of a good way to limit the number of emails sent by Elmah during a time period like you can with Health Monitoring?
I want to be able to limit the emails for each error from each page to only an email once an hour or so for that particular error and page.
Looking at the elmah documentation it looks like using:
void ErrorMail_Filtering(object sender, ExceptionFilterEventArgs e)
{
// perform filtering here
}
in the global.ascx file might be an option. I could setup a static object per application that contains some the error details and the time logged and check it and cancel the email notification if need be?
I'm trying to set up ELMAH for error logging in my app. Here's my web.config:
<configuration>
<configSections>
<sectionGroup name="elmah">
[code]...
We are using the approach described here to log our webservice errors with Elmah. And this actually works, but sadly the username beeing logged is empty.
We did some debugging and found, that when logging the error in the ErrorHandler the HttpContext.Current.User has the correct User set.
We also tried:
HttpContext context = HttpContext.Current;
ErrorLog.GetDefault(context).Log(new Error(pError, context));
and
ErrorLog.GetDefault(null).Log(new Error(pError));
Without success.
how we can make Elmah log the username?
On a sidenote, when logging the error directly within the Webservice, the username is logged as expected. But taking this approach is not very DRY.
First I found that you can catch it and log it inside a catch, but this doesn't send an email.
Then I found out about using the Error Signal class. That worked, however what wasn't apparent from reading, is that it treats the error like normal, so when I signal the error it goes to the custom error page still, I don't want that to happen. What I want to do is catch that error, log it, send the email, but stay on the page the error happened so I can provide special feedback. I do not want it go to the custom error page.
EDIT: This is what I have and it redirects me to the custom error page.
Try
smtpClient.Send(mailMessage)
Catch smtpEx As SmtpException
errorSignal.FromCurrentContext().Raise(smtpEx)
Catch ex As Exception
errorSignal.FromCurrentContext().Raise(ex)
End Try
Edit: Posting my web.config sections that involve Elmah (besides the connection string hah)
And there is nothing in my Global.asax file involving Elmah.
