Found the answer at http://discuss.hangfire.io/t/checking-for-a-job-state/57. Through
var succeededJobs = JobStorage.Current.GetMonitoringApi();
foreach (var succeededJob in succeededJobs.SucceededJobs(0, System.Convert.ToInt32(succeededJobs.SucceededListCount())))
{
…
}
I can monitor queues available for job assignment as the Dashboard does, and I can monitor Servers available for queue assignment. As well, by having the app SignalRHub poll for succeeded jobs in Heartbeat*n intervals, SignalR can clear the server-queue mapped pair for further duty and inform the desktop of jobs that complete in a rolling stream, as they complete. It would be good if a queue state event change could throw a signal through SignalR to registered app hubs so that listening rather than polling could be implemented from the app SignalR hub.
I’m still working my way through documentation supplemented by Hangfire source code. I am sure there are more efficient and elegant ways to implement what I am doing. But at least I am getting it done in the above manner…and can go back and refactor it later as I become more knowledgeable about the API source code.
Love the Hangfire API and code. Tx.
