Poolex.Private.DebugInfo (poolex v1.4.0)
View SourceInformation with the current state of the pool.
Can be used for debugging.
Summary
Functions
Returns detailed information about started pool.
Types
@type t() :: %Poolex.Private.DebugInfo{ busy_workers_count: non_neg_integer(), busy_workers_impl: module(), busy_workers_pids: [pid()], failed_to_start_workers_count: non_neg_integer(), idle_overflowed_workers_count: term(), idle_overflowed_workers_impl: term(), idle_overflowed_workers_pids: term(), idle_workers_count: non_neg_integer(), idle_workers_impl: module(), idle_workers_pids: [pid()], max_overflow: non_neg_integer(), overflow: non_neg_integer(), waiting_callers: [pid()], waiting_callers_impl: module(), worker_args: [any()], worker_module: module(), worker_shutdown_delay: timeout(), worker_start_fun: atom() }
Functions
@spec get_debug_info(Poolex.pool_id()) :: t()
Returns detailed information about started pool.
Primarily needed to help with debugging. Avoid using this function in production.
