Points out the relevant problems in the enterprise and it's easy to understand

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.

Quotes from Members

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

Pros

"Clicks to root cause - fast & easy to diagnose and deep-dive"
"As an Administrator, before we bought this AppInternals, I didn't have visibility on why items were slow or why an application was not running. This gives us the ability to see what's going on. The application is load balancing. We can now see if its own server has issues or just one specific server has issues."
"I like it that one can match IPs with the application name."
"The most valuable aspect of this solution is the integration with their other systems. It's easy to understand and it points out the relevant problems in the enterprise."
"The capability of analysing each individual transaction captured to a very low level detail (method call/line of code)."
"Transaction Tracing is the most useful. Being able to have the transaction stitched together so we can see where the problem is has proven invaluable."
"Browsermetrix, which is real-user monitoring via JS injection and linked back to TTW via cookie. It allows us to see the experience of every user hitting our sites and analyze performance by region, browser, etc."
"We just control on the backend of AppInternals what we want to instrument and what we don't want to instrument."
"Synthetic testing is by far the most valuable feature in our organization."
"Datadog has positively impacted my organization by shortening our time to resolve incidents because it's a central place for getting all the data that we need for troubleshooting."
"It is a good one stop location where we keep all our data for our infrastructure, and it's also easier to navigate between different things."
"The intuitive user interface has been one of the most valuable features for us."
"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."
"Datadog has positively impacted my organization by making finding and resolving issues a lot easier and efficient."
"With Datadog, we managed to get everyone on board into a single place and a single tool, providing teams with one spot where they can check everything related to monitoring, and enabling management and leadership to have an overview of all tools working together."
"Because of our client focus, it is easy for us to sell. This is because it is easy to use and easy to set up."
 

Cons

"Deployment and agent patch management is not managed centrally, resulting in a large level of effort to update."
"The technical support is not very good and should be improved."
"I would like for it to have automated updates, the way the product updates itself should be all automated, as opposed to what it is now."
"The admin dashboard could be easier as it takes a little bit of time to get used to it."
"They should find a way for report generation from TTW to run quicker."
"We have put in a request as an enhancement that we would like to search for items. If we're searching for a URL and we want to know was it a get or was it a post."
"The recording mechanism for synthetic transactions could be improved as well."
"It would be great if the solution could offer fixed bundles and more features."
"I find the setup cost to be too expensive. The setup cost for Datadog is more than $100. I am evaluating the usage of this solution, however, it is too expensive."
"The hardest thing we experience is just training people on what to search for when identifying a problem in Datadog, and having some additional training that might be easily accessible would probably be a benefit."
"We would love to see a % consumed and alert us if we are over budget before getting an overage charge 20 days into the month."
"I would like testing for data in the future."
"Datadog can be improved by addressing billing and spend calculation methods, as it would be better if these were more straightforward."
"My experience with pricing, setup cost, and licensing is that it is really expensive."
"Datadog could be improved if it could detect other software in a container or server."
"It would also be nice if we had more insight into our own usage of Datadog (agents and custom metrics). They provide a usage page which does help, but it is not in real-time."
 

Pricing and Cost Advice

"The licensing model is expensive compared to its competitors, but the service it gives to your business, and the data quality, means that it's worth it."
"The licensing model for v9 is better where it is an individual license per server, while v10 licenses are per JVM/ .NET and server instance. The latter model appears to be the model that other APM vendors are using."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"This solution is budget friendly."
"The pricing and licensing through AWS Marketplace has been good. It would be nice if it was cheaper, but their pricing is reasonable for what it is. Sometimes, for their newer features, they charge as if it's fully fleshed out, even though it is a newer feature and it may have less stuff than their other items."
"The cost is high and this can be justified if the scale of the environment is big."
"It has a module-based pricing model."
"​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."
"They prefer monthly subscriptions."
