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.

Troubleshooting at the packet level helps us resolve issues more quickly
The solution provides increased visibility during an IT deployment. It enables us to troubleshoot a service when it is down. As we expand our company, more users are using the tool to quickly resolve issues. It helps us and them get to root cause quickly. For example, last week a DNS was not running anymore. We checked the packet and saw that there was a buffer overload. It has cut our overall troubleshooting time. Sometimes it took a month to troubleshoot something that we can now do within days. nGenius has helped increase application or network uptime. The DNS I mentioned is now a better server with more capacity than before, because of our troubleshooting. We see a measurable decrease in mean time to know and mean time to repair. We see that when our customers are using this tool, their stability on the link is getting better and better, every time they use it. Also, we use the solution for unified communication application performance and it helps with uptime and end-user experience. Sometimes the quality of voice calls is not good enough, so we use the Media Monitor to check the quality in real-time.

Quotes from Members

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

Pros

"The integration and configuration are incredibly simple. The SaaS offering is remarkably easy to set up, especially if you're coming from a Graphite environment or anything that uses a StatsD."
"Profiling has been made easier."
"Synthetic testing is by far the most valuable feature in our organization."
"Its logs are most valuable."
"Customizable views as well as the ability to "dive in" when we see someting anomalous has improved the workflow for handling incidents."
"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."
"It provides more cloud data. They tend to just get the way a service would be designed on the cloud."
"The ability to send notifications based on metadata from the monitor is helpful."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"One of the valuable features is the packet decoding."
 

Cons

"Graph filters for logs need to be set manually which works well for JSON but not for unstructured logs."
"We did have an issue where a synthetic test was set up before the holiday break, and we were quickly charged a great amount. Our team worked with Datadog, and they were able to help us out since it was inadvertent on our end and was a user error."
"Network device and performance monitoring could be improved, as we've faced some limitations in this area."
"They need to offer better/more customization on what logs we get and making tracing possible on Edge runtime logs is a real requirement."
"The FinOps needs improvement."
"The correlation between the logs and the metrics needs improvement as most cases, we might use another logging tool (that is cheaper in cost) which we then have to link together."
"All solutions have some area to improve, and in Datadog they can improve their overall technology moving forward."
"We need more advanced querying against logs."
"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
 

Pricing and Cost Advice

"The cost is high and this can be justified if the scale of the environment is big."
"While it is an expensive product, I would rate the pricing level at four out of five."
"The solution's pricing depends on project volume."
"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."
"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"​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."
"Sometimes it's very hard to project how much it will cost for the monthly subscription for the next month when you add certain features. Having better visibility of the cost would give a better experience."
"It has a module-based pricing model."
"Licensing is quite expensive."
