In the above query you can change what you consider to be good, acceptable and bad by modifying the comparisons on line 3 and 4. In the honeycomb visualization ensure the data mapping value is set to the availability and the displayed field is the http check so that the “open with” feature will work.
The above is only for SaaS and the new dashboards. To access the new dashboards search for dashboards and select “Dashboards” and not “Dashboards Classic” as seen below. The docs that @p_devulapalli mentioned are a good place to start if you have access.
Otherwise if you are constrained to Dynatrace managed or dashboards classic then below would do the trick and then you can pin it to a dashboard from that view.
