Between 27/May/2020 19:10 UTC and 28/May/2020 20:40 UTC, users who have not upgraded to our new Metrics Agent for Monitoring were unable to view their Droplet graphs. This has since been resolved. However, we still recommend that users install our newer Metrics Agent. You can find instructions on how to install the Metrics Agent here:https://www.digitalocean.com/docs/monitoring/how-to/install-agent/
We apologize for any inconvenience caused by this. If you have any questions regarding this, or continue to experience any issues with your graphs, please open a support ticket inquiry so that our support team can assist you.
