The integration is built specifically for Azure Functions. Sleep well at night knowing that every function errors is persisted in elmah.io.
All configuration is available through JSON, making it possible to have a log per function and even monitor the same function in different regions.
Automatically store properties from FunctionFilterContext. Attaching filter properties on errors makes it easier to track down bugs.
The client doesn't stop with Functions. Monitoring Azure WebJobs is fully supported with the same level of detail as with Functions.
