Designing a logging system for a mobile application

It is required to develop a logging architecture for an existing mobile product, covering about 100,000 active users. The application provides features for viewing location catalogs, navigating through events, and purchasing tickets. It is necessary to ensure the collection of detailed logs from the client side, their storage, and subsequent flexible filtering (by user, city, event) and search for specific issues (e.g., "failed to purchase ticket").
