Featured Reviews

Kevin Palmer - PeerSpot reviewer
Useful log aggregation and management with helpful metrics aggregation
Datadog provides us value in three major ways: First, Datadog provides best-in-class functionality in many, if not all, of the products to which we subscribe (infrastructure, APM, log management, serverless, synthetics, real user monitoring, DB monitoring). In my experience with other tools that provide similar functionality, Datadog provides the largest feature set with the most flexibility and the best performance. Second, Datadog allows us to access all of those services in one place. Having to learn and manage only one tool for all of those purposes is a major benefit. Third, Datadog provides significant connectivity between those services so that we can view, summarize, organize, translate and correlate our data with maximum effect. Not needing to manually integrate them to draw lines between those pieces of information is a huge time savings for us.
Srinivasulu Soolluru - PeerSpot reviewer
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.
