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

"It has scaled great. I haven't run into any problems anywhere that I've used it. They have handled everything that we have needed them to."
"Excellent autocomplete for everything in the UI."
"The ease of correcting these dashboards and widgets when needed is amazing."
"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 dashboards are super convenient to us for a more zoomed out view of what is going on with each integration that we utilize."
"Datadog agents act as an integration to different services, providing easy access and management."
"Going from viewing a metric to creating a monitor alerting on a metric is very easy."
"The ease with which we can filter, use metrics, and give accounts to customers, then let the customer filter, set up metrics, and alerts. This has been a big win for us."
"The score-based application performance ratings help the network team."
 

Cons

"Network device and performance monitoring could be improved, as we've faced some limitations in this area."
"I spent longer than I should have figuring out how to correlate logs to traces, mostly related to environmental variables."
"Datadog has a lot of documentation, but a lot of that documentation assumes you know how the service works, which can lead to confusion."
"One area where I was really looking for improvement was the CSPM product line. I had really wanted to have team-level visibility for findings, since the team managing the resources has much more context and ability to resolve the issue, as the service owner. However, this has been added to the announcement in a recent keynote."
"It could use some additional features when working with metrics like Grafana or like New Relic has. Datadog does not use library technologies like Dynatrace does. Datadog has machine learning too, but it does not have this option in all layers of monitoring like infrastructure service process in applications."
"Alerting timing should be improved to be more fine-tuned and exact."
"The product needs to have more enterprise approach to configuration."
"The real issue with this product is cost control."
"The product must start using a bit more machine learning and AI, especially for security."
 

Pricing and Cost Advice

"The tool is open-source."
"It didn't scale well from the cost perspective. We had a custom package deal."
"This solution is budget friendly."
"They prefer monthly subscriptions."
"The price is better than some competing products."
"The solution is fairly priced but history and log storage can get costly depending on your needs."
"The pricing came up a bit compared to their competitors. It is not that the price has risen, but that the competitors have gone down. They keep adding more features that I would have expected to be baked in at a more nominal price. I have been increasingly dissatisfied with the pricing, but not enough to jump ship."
"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."
"The tool is very pricey."
