Hi Yuhao,
Really sorry, I have difficulty reading text on JPEGs. So I am not sure, and I do not understand which "import code" we are discussing. Is this a dashboard which lakeFS provides? Usually whoever provided the dashboard is most able to help.
Or, is this a question about which Prometheus metrics lakeFS exports? If you can describe what you want to measure, I will be able to either tell you which metric to use, or ask you to open an issue.
