Diagnostics

A collection of diagnostic bits and pieces for Elixir.

Examples:

Get module name from pid

Diagnostics.module_name(pid)

Get the size of a process

Diagnostics.size(pid)

Get the size of processes state

Diagnostics.state_size(pid)

Get a processes state

Diagnostics.state(pid)

List the processes in the system using the most memory (total heap) by module name and the count of them running on the node

Diagnostics.processes_by_module

List all processes created by Module MyModule in namespace MyApp ordered by size

Diagnostics.processes_by_size("MyApp.MyModule")

List top 10 processes created by Module MyModule in namespace MyApp ordered by size

Diagnostics.processes_by_size("MyApp.MyModule", 10)

List all processes ordered by size

Diagnostics.processes_by_size

List all processes created by Module MyModule in namespace MyApp ordered by proc bin size

Diagnostics.processes_by_large_binary_size("MyApp.MyModule")

List top 10 processes created by Module MyModule in namespace MyApp ordered by proc bin size

Diagnostics.processes_by_large_binary_size("MyApp.MyModule", 10)

List all processes ordered by proc bin size

Diagnostics.processes_by_large_binary_size

These can also be run on a remote node e.g

:rpc.call(@node_name, Diagnostics, :module_name, [pid])
