Let me start by saying while "Errors" in this case does sound very bad, informational messages are also considered "Errors" in certain instances - so you're seeing errors/sec counter values but it doesn't necessarily mean all of them are bad.
If you want to track what is happening, I would suggest using Extended Events, since Traces are deprecated and do not gather all of the same data. The link will take you to a post where you can copy and paste, no sense reinventing the wheel here.
It is up to you to decide if these errors warrant more investigation or not. Do be warned, if you're getting 2 errors every 10 seconds that will extrapolate into 720 errors/hour or 17,000 errors a day... I highly doubt you want to go over all of them by hand - bucketing them (modifying the query on the blog) can remove most of the noise.
