Dhroov Patel - PeerSpot reviewer
Site Reliability Engineer at Grainger
Has improved incident response with better root cause visibility and supports flexible on-call scheduling
Datadog needs to introduce more hard limits to cost. If we see a huge log spike, administrators should have more control over what happens to save costs. If a service starts logging extensively, I want the ability to automatically direct that log into the cheapest log bucket. This should be the case with many offerings. If we're seeing too much APM, we need to be aware of it and able to stop it rather than having administrators reach out to specific teams. Datadog has become significantly slower over the last year. They could improve performance at the risk of slowing down feature work. More resources need to go into Fleet Automation because we face many problems with things such as the Ansible role to install Datadog in non-containerized hosts. We mainly want to see performance improvements, less time spent looking at costs, the ability to trust that costs will stay reasonable, and an easier way to manage our agents. It is such a powerful tool with much potential on the horizon, but cost control, performance, and agent management need improvement. The main issues are with the administrative side rather than the actual application.
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

"If we have a large load for users using our basic Datadog, it will immediately fire off an alert notifying us either something's wrong or not."
"Even if something goes wrong and the Datadog tenant becomes completely compromised or if all our monitors were to get erased for whatever reason, we can always restore all our monitoring setup through Terraform, which provides peace of mind."
"The setup cost was minimal."
"Datadog has allowed us to ensure that we can look at how our beta testers are using our new UIs and seeing where their frustration points are, which has been important to us."
"The best way it has helped us is by consolidating all our logs into a single place and making it easier to find errors."
"The solution's SaaS model is easy to manage and works well in single- or multi-cloud environments."
"Thanks to the logs, we manage to make better reports through Jira and also to trace the request with more facility than we would be able to do otherwise."
"The application performance monitoring is pretty good."
"The score-based application performance ratings help the network team."
 

Cons

"The product can be improved by allowing the grouping of APIs to add variables. That way, any API with a unique ID could be grouped together."
"We have asked technical support questions, and sometimes they don't get back to us right away. Or when they do, it is not the right answer."
"The incident management beta looks promising, but it is still missing the ability to automatically create incidents based on certain alerts."
"The product needs a better Datadog agent installation."
"While the UI and search functionality are excellent, further improvement could be made in the querying of logs by offering more advanced templates or suggestions based on common use cases."
"There are some areas on log filtering screens where the user interface can take some getting used to."
"We want to reduce having to go to different screens to obtain all the information."
"A big problem with Datadog is the billing. They need to make the billing more user-friendly."
"The product must start using a bit more machine learning and AI, especially for security."
 

Pricing and Cost Advice

"​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 solution is fairly priced but history and log storage can get costly depending on your needs."
"If you do your homework, you'll find that if you're really concerned with cost, it's good."
"Our licensing fees are paid on a monthly basis."
"The price is better than some competing products."
"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."
"Pricing seemed easy until the bill came in and some things were not accounted for."
"The solution's pricing depends on project volume."
"The tool is very pricey."
