Correlations feature
We have launched a new feature on elmah.io called Correlations. With Correlations, you can correlate/group log messages across multiple sites and services together. Think of a console app calling an API that puts a message on a queue that a service consumes. By correlating log messages from all three processes, you will be able to see a shared trace of what happens.
I won’t go into more detail here, since the feature is already described here: How to correlate messages across services. The Correlations feature is currently in beta and will in some cases require you to install prerelease NuGet packages. I look forward to hearing what you think.
