@spec info( pid :: pid() | list() | binary() | integer() | {integer(), integer(), integer()} ) :: :error | map()
Creates a complete overview of process stats based on the given pid
.
Including but not limited to:
id
, the process pidname
, the registered name ornil
.init
, initial function or name.current
, current function.memory
, the total amount of memory used by the process.reductions
, the amount of reductions.message_queue_length
, the amount of unprocessed messages for the process.,
@spec list() :: [map()]
Retreives a list of process summaries.
Every summary contains:
id
, the process pid.name
, the registered name ornil
.init
, initial function or name.current
, current function.memory
, the total amount of memory used by the process.reductions
, the amount of reductions.message_queue_length
, the amount of unprocessed messages for the process.
Creates formatted meta information about the process based on the given pid
.
The information contains:
init
, initial function or name.current
, current function.status
, process status.
@spec pid( pid :: pid() | atom() | list() | binary() | integer() | {integer(), integer(), integer()} ) :: pid() | nil
Turns the argument pid
into a pid or if not possible returns nil
.
It will accept:
- pids
- atoms / module names (registered processes)
- single integers
- a list of 3 integers
- a tuple of 3 integers
- a charlist in the format:
'<0.0.0>'
- a String in the following formats:
"#PID<0.0.0>"
"<0.0.0>"
- atom / module name
Example:
iex> Wobserver.Util.Process.pid pid(0, 33, 0)
#PID<0.33.0>
iex> Wobserver.Util.Process.pid :cowboy_sup
#PID<0.253.0>
iex> Wobserver.Util.Process.pid Logger
#PID<0.213.0>
iex> Wobserver.Util.Process.pid 33
#PID<0.33.0>
iex> Wobserver.Util.Process.pid [0, 33, 0]
#PID<0.33.0>
iex> Wobserver.Util.Process.pid '<0.33.0>'
#PID<0.33.0>
iex> Wobserver.Util.Process.pid {0, 33, 0}
#PID<0.33.0>
iex> Wobserver.Util.Process.pid "#PID<0.33.0>"
#PID<0.33.0>
iex> Wobserver.Util.Process.pid "<0.33.0>"
#PID<0.33.0>
iex> Wobserver.Util.Process.pid "cowboy_sup"
#PID<0.253.0>
iex> Wobserver.Util.Process.pid "Logger"
#PID<0.213.0>
iex> Wobserver.Util.Process.pid 4.5
nil
@spec pid!( pid :: pid() | list() | binary() | integer() | {integer(), integer(), integer()} ) :: pid()
