Hi Fabian and team, I'm using the API name, version, consumer name, response latency, status code, and many metadata for Histrogram labels. With the live traffic, those labels assign different values, and a lot of histogram child objects are created. That is caused by the OOM of the JVM. I would like to know what is the best and recommended way to export those values.
