Hi guys! I have searched for a solution which do not involve newrelic. In fact I'm more focused on splunk but I can't see something available. Is there anything which could be used and what will be the steps to make a integration for splunk.

By default you can also use tideways (IMO way better suited for PHP than Newrelic) or blackfire (as far as I know more focused on performance topcis only and less on error catching and analysis). Splunk is not supported out of the box in Spryker (to my knowledge)

What is IMO? Yeah blackfire is really good for performance tests.

IMO = In my opinion

Yeah I agree the thing is splunk is the main tool for our work.

Then the answer is

Splunk is not supported out of the box in Spryker (to my knowledge)

Meaning you will need to implement sending data to Splunk on your own. But the newrelic and tideways implementation might serve as a good example on how to implement it. Probably it will require having a collector container/agent like tideways/newrelic, but I'm not too familiar with Splunk. This would require an infrastructure change in the Spryker PaaS (assuming you already run in the cloud) that needs an implementation on Spryker side. So I suggest you reach out to the customer support and ask them if they either already support Splunk or what are your options to get it supported.
