Single pane of glass, easy to share dashboards, and good for monitoring
We've had some issues where we had Datadog automatically turned on in AWS regions that we weren't using, which incurred a small but steady cost that amounted to tens of thousands of dollars spent over a few weeks. I wish there was a global setting that lets an admin restrict which regions DD is turned on in as a default setup step. Sometimes, the APM service dashboard link isn't sharable. I click something in the service catalog, and on that service's APM default view, I try to share a link to that with a teammate, and they reach a blank or error screen. I wish there was more organization and detail in the suggestions when I use the query editor. I'm never quite sure when the autofill dropdown shows up if I'm seeing some custom tag or some default property, so I have to know exactly what I'm looking for in order to build a chart. It's hard to navigate and explore using the query autofill suggestions without knowing exactly what tag to look for. It's been a bit hard to understand how data gets sampled or how many data points a particular dashboard value is using. We've had questions over the RUM metrics that we see and we had to ask for help with how values are calculated, bin sizes, etc to get confidence in our data.

It speeds up incident response by automating alerts and ticket creation
When configuring a dashboard, we can write search criteria. Based on the search criteria, the dashboard shows all the alerts, including the alert time, creation time, and a summary description of the alert. When you add an extra column, such as the user that triggered the alert, the next time he refreshes the dashboard, he wants to know that the alert is acknowledged. We want to improve that comment feature. In the Service Analyzer, we monitor the network infrastructure services and have a KPI for each service. When the value exceeds the threshold value, we can add the colors. For example, we can set it to green when the threshold value is within the limit. If it is red, then the value has passed the threshold. We want more colors in the service analyzer to display all these features.
