The Victoriametrics that currently PMM is using has a bug that takes too long time to start the newly added scrapers.
So, last year, I reported this issue to the Victoriametrics community, and they fixed that issue in v1.87.1.
So, my question is when PMM can adopt the new version of the Victoriametrics for PMM? It seems that the PMM is using v1.82.1 at the moment.
