Samplers can rely e.g. on the Memsup functionality, the memory usage BIFs, monitoring the size of ets tables, system_info(process_count), etc. - whatever works as good proxies for resource usage in your system.</div><div><br class=""></div><div>BR,</div><div>Ulf W</div><div><br class=""></div><div>[1] <a href="https://github.com/uwiger/jobs" class="">https://github.com/uwiger/jobs</a></div><br class=""><div apple-content-edited="true" class="">
