recon's Introduction

recon

Recon wants to be a set of tools usable in production to diagnose Erlang problems or inspect production environment safely.

To build the library:

rebar compile

Documentation for the library can be obtained at http://ferd.github.io/recon/

It is recommended that you use tags if you do not want bleeding edge and development content for this library.

Changelog

  • 1.2.0:
    • add recon_alloc:snapshot* functions, which allow memory allocation snapshots to be taken, saved on disk, reloaded, and analyzed on-demand. Thanks to Lukas Larsson for this functionality.
  • 1.1.0:
    • add recon_lib:term_to_port to convert a string back to a usable port.
    • add recon:port_info/1 and recon:port_info/2
    • add recon_alloc module
  • 1.0.0: add info/2 and info/4. The memory info type thus gets renamed to memory_used, in order to avoid conflicts when picking between a type and a specific process attribute. Types exported by the module also get updated.
  • 0.4.2: extended app_deps.erl to read apps/ directories for releases
  • 0.4.1: fixed bug where nodes with lots of processes could see the GC call fail if said processes failed between long calls within the bin_leak function call.
  • 0.4.0: fixed bug where nodes with lots of processes or ports could see their count or window functions fail because a process or socket closed between the time the function started and before it finished. This ends up changing the API in recon_lib for the window and count functions that take a specific pid as an argument.
  • 0.3.1: factored out some logic from recon:info/1 into recon_lib:term_to_pid and allowed arbitrary terms to be used for pids in recon:get_state/1.
