If this is for fun and a learning project I say go for it there's a lot of things you can touch on and learn - gathering what queries are being run by ignition, parsing the logs etc. Ignition already logs slow queries and I have a script to fetch them from a while ago.
If this is for production I might say to not bother. Find the slow queries that Ignition logs, use your database software of choice to analyze the query and dissect from there. Theres not much more to it in my experience and I don't know what value add Ignition will do for you here outside of maybe curating slow queries into a db / email for you or a DBA on a regular basis which could admittedly be helpful.
