Hey again, do you mean by "rate of errors" the ratio between errors and the total number of requests? If it is just the rate (as in the number of errors per second) you can just replace `increase` with `rate`. This will give you the errors per second averaged over the last 5 minutes.
How does the label mismatch manifest itself? Is it just the label names or do the values differ as well? Can you post the respective labels of interest to you?
