We recently installed DPM as part of a POC for monitoring Atlas MongoDB; and much like we saw in the original demo with the SE team, the DPM Summary screen is not capturing any Resource Health metrics (CPU, Memory, etc.). We opened support case #00868774 and were informed currently, DPM does not provide or Support the Altas fetch for server stats and that this is already a Request for DPM to provide this Metric.
Not having these metrics in DPM makes the product less appealing as the whole reason we were considering it for our performance monitoring needs for our Atlas environments is because the Atlas KPIs are limited.
