Although I have been idle for a long time as a freelancer, I have a lot of experience in commercial projects. Currently, I am directly involved in the implementation of ELK Stack, including the design and management of indexes, templates and lifecycle policies. I can help you solve your problem very quickly, but sometimes ELK seems to be an unpredictable beast, so I leave some room to fine-tune the details.
Best regards,
