Metrics Page Improvements & Documentation update

[Kemi-Elizabeth]

Where on docs.platform.sh should be changed?

With the work to update and improve the Metrics page — the following pages will most likely require some changes:

https://docs.upsun.com/increase-observability/metrics.html

https://docs.platform.sh/increase-observability/metrics.html

https://docs.platform.sh/increase-observability/metrics/grid.html

https://docs.platform.sh/increase-observability/metrics/dedicated.html

https://docs.platform.sh/increase-observability/metrics/dedicated-generation-3.html

What exactly should be updated?

Some changes required: Screenshots to reflect changes (e.g., now showing RAM for services on Platform.sh Grid, removal of label mentions ( critical, warning, burst )

Changes are summarized in the following Slack thread:

In short:

• Absolute values are changed to percentages on the Y-axis
• Threshold lines are still color-coded
• The threshold labels (warning, critical) are removed.
• These changes apply across all infrastructures and on Upsun/Platform.sh
• Also, the RAM graph for services is back on Platform.sh — It was removed a year ago but is brought back along with the changes above to remove anxiety.
