I have an API which has a known error which I want to ignore, I do not want to use the ignore error functionality as I want to keep the error for prioritisation on a backlog. I know the error and the request_uri on which to filter. What I would like is a NRQL query which I can then set the condition to fire above 5% in 3 minutes.
We are running the .Net agent for this so the differences between Transaction errorMessage and TransactionError need to be compensated for.
I think that I actually know the answer, just posting this for other forum visitors to practice on and for future reference. The solution will be posted on the NRQL library
