I'm looking into setting up some graphs for tracking metrics of our app for things that affect the customers. Things like: * Time to first byte * Response time * Full page load * CSS size * Count of CSS selectors Am I missing any important ones? I'm thinking I might need to track JS, but not really sure what aspects of it.
We already have internal graphing software I can hook data into, I'm just trying to figure out how to actually generate this data. Anyone know any services that'll already do this? Or is this gonna be something I need to write myself?
