Featured Reviews

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.

Network Engineer at Inniti Network Solution
A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

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

Pros

"The solution is good for complex integations which have lots of downstream and involve multiple combined systems."
"Synthetic testing has been a game-changer, allowing us to catch potential problems before they impact real users."
"The solution allows flexibility and heightened observability for presenting data, creating indicators, and setting service-level objectives."
"The APM has made observability and tracing more accessible to developers."
"Both the engineering team and the product team are seeing tremendous value from this solution."
"The observability pipelines are the most valuable aspect of the solution."
"The dashboards and the performance of the software have been great."
"The solution has helped out organization gain improved visibility."
"One of the valuable features is the packet decoding."
"Sometimes it took a month to troubleshoot something that we can now do within days."
"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
 

Cons

"Alerting timing should be improved to be more fine-tuned and exact."
"The logging could be improved in the future."
"The real issue with this product is cost control."
"It does not have the best interface."
"We would like to see some versioning system for the Synthetic Tests so that we could have a backup of our tests since they are time-consuming to make and very easy to damage in a moment of error."
"I find the training great. That said, it is set for the LCD (lowest common denominator). Of course, this is very helpful to sell the product, yet, to really utilize the product, you need to get more detailed."
"For specialized support, it feels like you're under-staffed, having to wait days/weeks for a solution is a big NO-NO."
"Datadog's roadmap can be a bit unpredictable at times."
"I would say that this is not a scalable solution."
"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."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"Room for improvement exists in filtering in the packet decode."
 

Pricing and Cost Advice

"While it is an expensive product, I would rate the pricing level at four out of five."
"Pricing seemed easy until the bill came in and some things were not accounted for."
"The solution's pricing depends on project volume."
"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."
"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."
"It costs the same amount it would if we were hosting it ourselves, so we are incredibly happy with the cost."
"It didn't scale well from the cost perspective. We had a custom package deal."
"Datadog does not provide any free plans to use the solution. When I start with a proof of concept it would be sensible to have a free plan to test the tool and check whether it fits the requirements of the project. Before the production stage, it is always good to have a free plan with some limited features, number of requests, or logs."
"Licensing is quite expensive."
