Description

Currently - online monitoring retries 3 times with .1 s inbetween...
I would like to see online monitoring to be able to be started first and/or
persist across multiple runs.

I've started to make some changes to TransferWrapper on artdaq:feature/22882_TransferWrapper_ConnectionRobustness. I would like to get this code to a point where online monitors can be started at any time with respect to the DAQ and be able to connect and disconnect at will.

  • Status changed from Work in progress to Resolved

With the addition of a "allowMultipleRuns" parameter and a "dispatcherConnectTimeout" parameter, I have improved TransferWrapper so that it can wait up to a user-specified amount of time for the Dispatcher to enter the "Running" state (which it determines by querying the Dispatcher's status), polling for the Dispatcher's status every "dispatcherConnectRetryInterval_us" (defaults to 1 second, between 1000 us and 30 seconds). If allowMultipleRuns is false, the online monitor will terminate when it receives an EndOfData Fragment (current behavior), otherwise, it will re-enter the Dispatcher connection routine.
