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.

A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The agents feature in Datadog stands out as a valuable asset within our organization due to its robust functionality, versatility, and role in providing comprehensive monitoring and observability capabilities."
"With Datadog I can look at the health of the technology stack and services."
"The web app has a real-time support chat window in which a support engineer is chatting with you within a minute."
"Most of the features in the way Datadog does monitoring are commendable and that is the reason we choose it. We did some comparisons before picking Datadog. Datadog was recommended based on the features provided."
"Integrating Datadog with other platforms has made our monitoring processes a bit easier. It's not super simple, but it's manageable."
"Log analytics give us a powerful mechanism for error tracking, research, and analysis."
"The solution has offered increased visibility via logging APM, metrics, RUM, etc."
"The most valuable features are the dashboards and the reporting."
"One of the valuable features is the packet decoding."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
 

Cons

"I think better access to their engineers when we have a problem could be better."
"It would be great if usage metrics were automatically created and we could create custom metrics, instead we ended up building some of our own stuff to track and alert on our own usage."
"I love to have some DD guru come in and do a department training directly at our setup."
"I'd like to see an expansion of the Android and IOS apps to have a simplified CI/CD pipeline history view."
"To be very fair, I haven't had enough experience with Datadog to pick out improvements."
"We would like to see some versioning system for the Synthetic Tests so that we could have a backup of our tests since they are time-consuming to make and very easy to damage in a moment of error."
"The product could do better with its notifications."
"Alerting timing should be improved to be more fine-tuned and exact."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
 

Pricing and Cost Advice

"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"Pricing is somewhat affordable compared to other solutions but in order to really lower the costs of other products you need to plan very carefully your resources usage, otherwise, it can get expensive real quick."
"Our licensing fees are paid on a monthly basis."
"Datadog does not provide any free plans to use the solution. When I start with a proof of concept it would be sensible to have a free plan to test the tool and check whether it fits the requirements of the project. Before the production stage, it is always good to have a free plan with some limited features, number of requests, or logs."
"At my last company, we did see ROI, specifically around response time. We could get to mission critical things that were down and losing revenue on immediately. So, the product paid itself back."
"It didn't scale well from the cost perspective. We had a custom package deal."
"The tool is open-source."
"​Pricing seems reasonable. It depends on the size of your organization, the size of your infrastructure, and what portion of your overall business costs go toward infrastructure."
"Licensing is quite expensive."
