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.
Sunil K R - PeerSpot reviewer
Helps improve our incident response time, and our mean time to resolve, but visibility is limited
In my previous project, I successfully led the end-to-end deployment of a Splunk migration. The process went smoothly thanks in part to Splunk's professional services team. They conducted a thorough assessment, identified all our potential pain points, and developed a tailored solution and migration plan. This comprehensive approach ensured a seamless transition. Our core deployment team consisted of 5 internal members and two specialists from Splunk. Additionally, the project included a project manager and a product owner. We also benefited from the expertise of two professional service consultants and two representatives from the customer's side. An on-site admin architect further provided valuable technical support. Throughout the deployment process, we leveraged support from various resources whenever necessary. This included assistance with configuration changes, deployments, and other related tasks. We also collaborated effectively with our teammates to ensure a smooth and successful implementation.
