Which statistics/error collection system to choose?

Question

PHP

Hello! For example, there is an import of records to the site through an xml file. For each file import, I want to collect information in order to subsequently understand what went wrong. Errors can be system (exceeding the memory of the script, for example) and logical (there is not enough data for one of the imported records). After import, you need to see statistics - whether it was successful, and if not, then you need the opportunity to see the details. Were there logical errors, and if so, in what records.
Heard about Sentry, ELK, Datadog, Loggly but didn't use them at all. Through which logging system is it better to implement all this (not necessarily from those listed)?
And yet, do I understand correctly, is it better to collect the data from the application through Monolog?

Answer 1

Personally, I use Rollbar , but I recommend trying a few and understanding which system is more convenient for you, you can protest on an artificial project if you are afraid to leave tails on the worker.
And it's better to start using something than not to use anything.
You can walk around the sites and choose without going too deep, and then you can already understand whether the service is completely suitable or what functions are not there, and then you will choose more specifically.

Answer 2

$('.bar').on('change', function () { /* биндим событие на изменение ползунка */
    $('.clouds').each( function() { /* выбираем все тучки и для каждой выполняем следующее */
      this.top = $('.bar').value() * this.top;  /* здесь изменяем координату как вам удбно */
    });
  } );
