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.
JeroenDubbelman - PeerSpot reviewer
The product is extremely valuable and provides a lot of functionalities and visibility to organizations
The score-based application performance ratings help the network team. Often, customers have a siloed environment for security, applications, and servers. The network team is always asked to do troubleshooting. Being able to know how well an application worked in the past and what's happening today is really helpful. If someone has a complaint and the network team says that the problem is not on their side, they must be able to demonstrate it accurately. The network team is often given the least budget and the least number of employees. So, they must be able to troubleshoot and pinpoint problems as fast as possible. If it’s a network issue, they must fix it. However, if it is a cloud problem, an ISP problem, or a problem within the server or application environment, they must be able to demonstrate it clearly. It is the real benefit they get from the solution. Some of our customers are financial institutions. They use the tool for traffic accounting, especially when they get charged by ISPs or carriers for the amount of traffic they are using. In South Africa, we have banks that pay the service providers to allow customers to use their banking apps for free. The bank pays for it, not the customers. So, they need to compare to ensure they are paying for what has been used. Viavi enables them to do that. It is pretty much the best there is in the world. There is nothing to beat it. The product is extremely valuable and provides a lot of functionalities. It's really impressive.

Quotes from Members

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

Pros

"We enjoy the multistep API tests."
"The ease of use allowed me to get up to speed with log management since it's my first time using Datadog."
"This spectrum of solutions has allowed us to track down bugs faster and more rapidly, which allows us to limit revenue lost during downtime."
"Real user monitoring gives us invaluable insights into actual user experiences, helping us prioritize improvements where they matter most."
"The biggest thing I liked was the combination of all the things - monitoring, log aggregation, and profiling."
"We have found that we're able to get in and out of troubleshooting issues much more rapidly, which in turn, of course, enables us to spend more time on our products."
"The solution has helped our organization with custom events to track specific cases."
"It has turned into an operational dashboard. If you felt something is going wrong, you can immediately open up Datadog. It has been our go to application because we know the answer will be there."
"The score-based application performance ratings help the network team."
 

Cons

"There is occasional UI slowness and bugs."
"The product is quite complex, and there are so many features that I either didn't know about or wasn't sure how to use."
"I'd like to see an expansion of the Android and IOS apps to have a simplified CI/CD pipeline history view."
"The query performance could be improved, particularly when handling large datasets, as slower response times can hinder efficiency."
"I love to have some DD guru come in and do a department training directly at our setup."
"Datadog has a lot of documentation, but a lot of that documentation assumes you know how the service works, which can lead to confusion."
"We would like to see smaller or shorter tutorials and video sessions."
"We have contact with many customers that cover many areas, so we have cases where the infrastructure administration could be improved."
"The product must start using a bit more machine learning and AI, especially for security."
 

Pricing and Cost Advice

"I am not satisfied with its licensing. Its payment is based on the exported data, and there was an explosion of the data for three or four weeks. My customer was not alerted, and there was no way for them to see that there has been an explosion of data. They got a big invoice for one or two months. The pricing model of Datadog is based on the data. The customer was quite surprised about not being alerted about this explosion of data. They should provide some kind of alert when there is an increase in usage."
"Pricing and licensing are reasonable for what they give you. You get the first five hosts free, which is fun to play around with. Then it's about four dollars a month per host, which is very affordable for what you get out of it. We have a lot of hosts that we put a lot of custom metrics into, and every host gives you an allowance for the number of custom metrics."
"It didn't scale well from the cost perspective. We had a custom package deal."
"They prefer monthly subscriptions."
"​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."
"The tool is open-source."
"The price is better than some competing products."
"The solution's pricing depends on project volume."
"The tool is very pricey."
