Functions
available_worker(QueueManager::queue_mgr(), Timeout::timeout()) -> noproc | timeout | atom()
returns the first available worker in the pool
cast_to_available_worker(QueueManager::queue_mgr(), Cast::term()) -> ok
Casts a message to the first available worker. Since we can wait forever for a wpool:cast to be delivered but we don't want the caller to be blocked, this function just forwards the cast when it gets the worker
new_worker(QueueManager::queue_mgr(), Worker::atom()) -> ok
Mark a brand new worker as available
worker_ready(QueueManager::queue_mgr(), Worker::atom()) -> ok
Mark a worker as available
worker_busy(QueueManager::queue_mgr(), Worker::atom()) -> ok
Mark a worker as no longer available
worker_dead(QueueManager::queue_mgr(), Worker::atom()) -> ok
Decrement the total number of workers
pools() -> [pool_props()]
Return the list of currently existing worker pools.
stats(Pool_Name::name() (see module wpool)) -> proplist() (see module proplists) | {error, {invalid_pool, name() (see module wpool)}}
Returns statistics for this queue.
proc_info(Pool_Name::name() (see module wpool)) -> proplist() (see module proplists)
Return a default set of process_info about workers.
proc_info(Pool_Name::name() (see module wpool), Info_Type::atom() | [atom()]) -> proplist() (see module proplists)
Return the currently executing function in the queue manager.
trace(Pool_Name::name() (see module wpool)) -> ok
Default tracing for 5 seconds to track worker pool execution times to error.log.
trace(Pool_Name::name() (see module wpool), X2::boolean(), Timeout::pos_integer()) -> ok | {error, {invalid_pool, name() (see module wpool)}}
Turn pool tracing on and off.
