Grafana Home Dashboard Blank

Hi Guys, I’m running PMM 1.10v built from a market place AMI. Its been great for a week or more, but noticed as I’ve increased the number of MySQL instances the home dashboard takes longer to load graphs, and now they never load. They continually sit there spinning.

I have 11 MySQL instances so far, and the PMM server host is not under load, running at <20% cpu etc. (4core, 32GB instance). The Prometheus target status page shows scraps are all successful. I checked the Prometheus config and can see nothing obvious though I’m not familiar with Prometheus.

If you click through to individual graphs or other dashboards other than home, then metrics appear and everything is good.

Is there a some Prometheus or Grafana tweak I can do to solve the graph rendering on the home dashboard?

Thanks M
