SLOs in Dynatrace currently only work on rolling time frames, for example, the last 30 days. Dynatrace has said that they are basing their SLOs from what Google has done. In GCP, you can define SLOs on a Calendar Period or a Rolling Period. I personally think defining SLOs using a Calendar period, more specifically a Calendar Month, makes the most sense.
Are there plans to add the functionality to define SLOs over Calendar periods in Dynatrace?
