Return the contents of a worker's process log, if it is located on the same physical storage (including network storage) as the controller. This will generally behave for workers started with rrq_worker_spawn but may require significant care otherwise.
Arguments
- worker_id
The worker id for which the log is required
- controller
The controller to use. If not given (or
NULL) we'll use the controller registered withrrq_default_controller_set().
Value
A character vector, one line per line in the log. If logging is enabled but the worker has not produced any logs, this will be an empty character vector. If logging is not enabled, then this function will throw.
Examples
obj <- rrq_controller("rrq:example")
worker_id <- rrq_worker_list(controller = obj)[[1]]
tryCatch(
rrq_worker_process_log(worker_id, controller = obj),
error = identity)
#> <simpleError in rrq_worker_process_log(worker_id, controller = obj): Process log not enabled for this worker>
