Continuing the discussion from Stacktraces being cut off:
Thank you for sharing this snippet and the link. I’m wondering if there is a best practice on how to set this flag.
- There doesn’t seem to be a function for simply reading a system flag, is this so?
- It seems like there should be some way to start an app with this setting, is there some option to pass into
elixir --erl "backtrace, 20or something? - If this has to be done on startup, is there a community convention on where to put something like this, so other devs would know where to find non-default changes made to the system?
Where Next?

I can’t remember how you can set it at startup time but you can do it at runtime using
:erlang.system_flag(:backtrace_depth, new_depth). This returns the old value. The startup default is 8. Note that this sets the depth for all processes.shaheenery
Thank you @rvirding, I ended up doing just that in the
startcallback function of myApplicationmodule.Just like this for anyone else looking
