Hangfire: Is there a exception hook?

[cottsak]

So I can pump exceptions caught in a background job to something like https://github.com/NickCraver/StackExchange.Exceptional ?

I'm not sure about the hook thing, but you can manage exceptions in jobs using a JobFilter, and then reporting the exception to the external service.

public class ErrorReportingJobFilter : JobFilterAttribute, IElectStateFilter
{
    public void OnStateElection(ElectStateContext context)
    {
        // the way Hangfire works is retrying a job X times (10 by default), so this wont be called directly with a 
        // failed state sometimes.
        // To solve this we should look into TraversedStates for a failed state

        var failed = context.CandidateState as FailedState ??
                     context.TraversedStates.FirstOrDefault(x => x is FailedState) as FailedState;

        if (failed == null)
            return;

        //here you have the failed.Exception and you can do anything with it
        //and also the job name context.Job.Type.Name
    }
}

and then register the Job filter globally

GlobalJobFilters.Filters.Add(new ErrorReportingJobFilter());

This looks kool.

OnStateElection and OnPerformed doesn't work for me, because JobActivator.DisposeScope is called before OnStateElection/OnPerformed. Since I'm trying to resolve scoped dependency (CurrentAppContext) inside OnStateElection/OnPerformed I am getting the error:

System.InvalidOperationException: Scope was not available. Did you forget to call container.BeginScope()?
in Castle.MicroKernel.Lifestyle.LifetimeScopeAccessor.GetScope(CreationContext context)

I need to write some application variables from CurrentAppContext into the log.

Hangfire writes job's exceptions as WARN, not ERROR into the log. So how can I handle job exceptions inside DI/IoC scope?
