Good question! Grafana is often reached for as a solution here, but it has some limitations (Note: most of these limitations are completely logical when you think of Grafana's target use case, server and software monitoring):

- advanced transformations are impossible or at a minimum unwieldy, especially for users who are not comfortable in e.g. SQL

- not optimized for advanced HMI for complex systems that move through multiple states. Software systems like to decompose into smaller, modular systems... the physical world does not cater to these abstractions

- It focuses on real-time and recent data. Our customers want to pore over and compare data for years after it is recorded.

- Lack of vertical integration with our customers data sources
