Besides HTTPS we are working with an external security specialist in order to make sure, that your errors are kept safe at all times. For more details, check out Security.

Be aware that you should never give away your API key and log id to someone outside your team or corporation. API keys are used for getting errors through our public API, why this id should always be a secret.

You are in luck! This problem can be solved in numerous ways using elmah.io:

  • Expand individual errors and click the Hide option in the tools menu. This hides the error until you decide to unhide it.
  • Expand individual errors and click the Delete option in the tools menu. This removes an error for good.
  • Navigate to your log settings and select the Actions tab. Beneath this tab you can clear your entire log.
  • Use the Ignore Filter or Rules feature to ignore certain errors when they are logged.

ELMAH stands for Error Logging Modules and Handlers for ASP.NET and is the original and very successful open source project for logging errors from .NET web applications. elmah.io is a cloud service offering logging to the cloud from every web framework already supporting ELMAH. More details here: ELMAH and elmah.io differences.

No. A group of talented developers are maintaining and doing new development of ELMAH. elmah.io is maintained by us, though we love to help out on the ELMAH framework as well. Lucky for us, the maintainers behind ELMAH have been kind enough to send us multiple pull requests on the parts of elmah.io which are open source.

Yes and no. The persistence part and the elmah.io website are not open source. We open sourced a couple of the components we have written in order to make elmah.io work, as well as our NuGet packages for logging errors to elmah.io.

A lot of the internals of elmah.io are based on open source and we love making contributions to other projects.

elmah.io is built for .NET and JavaScript. Integrating with elmah.io from other languages is possible using our API. We have seen a lot of different integrations from our users over the years. The elmah.io API is a simple REST API that can ingest log messages from every programming language able to make web requests.

There are a few options for browsing through your errors, without visiting elmah.io:

  • Using the Rules tab of the log settings, you can execute custom rules each time a new error occurs. This way you can send yourself an email or make a HTTP request when new errors are logged.
  • ELMAH offers an error browser as well. This browser is available by visiting /elmah.axd on your own site (available for ASP.NET / MVC / Web API only).
  • We’ve developed an elmah.io Visual Studio extension, making it possible to browse your log(s) from within Visual Studio.
  • Finally we provide an API, making it possible to integrate anything with elmah.io. Please let us know if you build something cool.

Installation

Which (web)frameworks support elmah.io?

Every framework supporting ELMAH also supports elmah.io. Besides these, we maintain a range of integrations for popular logging frameworks like log4net, NLog and Serilog. We do a lot to test elmah.io with as many frameworks as possible and love writing about it. Find out how to integrate with elmah.io from various frameworks, by visiting docs.elmah.io.

Hard to say, but most likely this issue is caused by one of two reasons:

  1. You already have elmah.io configuration in your web.config file. Look for the <errorlog> element.
  2. Powershell does not have sufficient privileges to execute the install.ps1 script from the elmah.io NuGet package. Start Visual Studio as administrator or set ExecutionPolicy.

Payment

Can I upgrade my subscription after I sign up?

Of course. When you upgrade your subscription, elmah.io automatically generate the difference between what you've already paid and the new plan.

In most cases you can't. Please try out elmah.io by signing up for the trial plan. When you feel satisfied, upgrade to a paid plan for the full monty. Check out our Refund Policy for details.
