Minimal erlang system metrics collection
- Measure an mfa:
toolbox:measure(M, F, A)
- Measure an anonymous function:
toolbox:measure(fun() -> 3 + 2 end)
- Trace a process to get periodic updates
toolbox:trace(Name, Pid)
- Trace a registered process to get periodic updates
toolbox:trace(RegisteredName)
- Stop tracing a process
toolbox:untrace(Name)
-
Metrics function (metrics_fun): Module and function that represents a 2 arity function taking the name and relevant statistics in the form of a map:
-spec log(atom(), map()) -> ok. -
Metrics to collect (metrics): A list of metrics to collect, valid options include reductions and message_queue_len, or any numerical statistic from process_info
-
Enable node statistics (enable_node_stats): A boolean that declares whether to send node statistics in the form of
#{absolutes => ListOfAbsoluteStatistics, incrementals => ListOfStatisticsThatMakeSenseOverTime}
