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 product has offered increased visibility via logging APM, metrics, RUM, etc."
"We have been able to be a more confident, knowledgeable, and capable team when everything is being ported into a centralized format."
"Datadog has positively impacted my organization by making finding and resolving issues a lot easier and efficient."
"The installation step is pretty straightforward."
"We have way more observability than what we had before - on the application and the overall system."
"I find the greatest feature is being able to search across logs from various microservices."
"The seamless integration between Datadog and hundreds of apps makes onboarding new products and teams a breeze."
"However, Datadog has so far been a breeze to use and set up."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"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."
 

Cons

"Federated views for Datadog dashboards are critical as large companies utilize multiple instances of the product and cannot link the metrics or correlate the metrics together. This stunts the usage of Datadog."
"In terms of UI, everything is very small, which makes it quite difficult to navigate at times."
"The pricing model can be quite complex and might benefit from more flexible options tailored to different organizational needs."
"Additional metrics should be included."
"There are things about it that we would like to be fixed, such as it is taking averages of average. This results in data that we don't expect, but overall we are happy with it."
"The product is quite complex, and there are so many features that I either didn't know about or wasn't sure how to use."
"It can be overwhelming for new people as it has a lot of features."
"The documentation leaves a lot to be desired for new users."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"I would say that this is not a scalable solution."
"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
"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."
 

Pricing and Cost Advice

"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."
"It has always scaled for us. Cost scales up too, but that is not necessarily a bad thing. It's reasonable for what they're providing."
"If you do your homework, you'll find that if you're really concerned with cost, it's good."
"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."
"Our licensing fees are paid on a monthly basis."
"The price is better than some competing products."
"The tool is open-source."
"Licensing is quite expensive."
