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
Director at Bitrate
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

"Datadog has positively impacted our organization, as it has eliminated many negative issues, which I call tool sprawl, by replacing four or five separate monitoring tools with one unified platform."
"The platform appeals to companies spanning many industries on a global scale."
"The most valuable aspects of the solution include log search to help triage specific problems that we get notified about (whether by alerts we have configured or users that have contacted us)."
"The solution is sufficiently stable."
"The tools are powerful and intuitive to set up."
"Datadog is easy to use and easy to deploy, and it's a better solution compared to others on the market in terms of being budget friendly for our customers."
"In terms of the public cloud provider integration of AWS, I would say it's very easy and straightforward to integrate."
"Sometimes it's more user friendly for development teams, and there are parts of Datadog that are more understandable for development teams; for example, the APM in Datadog works more manually and works like the tools in New Relic, Grafana, or Elastic, making it easier to understand for software development teams."
"The score-based application performance ratings help the network team."
 

Cons

"The query performance could be improved, particularly when handling large datasets, as slower response times can hinder efficiency."
"Ingesting data from various sources to monitor the log metrics of the system can always improve so that, if something goes wrong, the right teams are alerted."
"The only issue I face is when more than one person editing these dashboards simultaneously, one or the other person sometimes loses his/her work."
"It's not that straightforward when creating an alert. The syntax is a little confusing."
"I would also like to see an improvement in the server's data extraction times, as sometimes it can take up to ten minutes to download a report for a critical issue that is costing us money."
"The pricing model hurts and forces us to work around the tool sometimes."
"There are so many different solutions; it is sometimes difficult to gauge where to start, and I sometimes miss a lot of functionality."
"Geo-data is also something very critical that we hope to see in the future."
"The product must start using a bit more machine learning and AI, especially for security."
 

Pricing and Cost Advice

"Pricing seemed easy until the bill came in and some things were not accounted for."
"It didn't scale well from the cost perspective. We had a custom package deal."
"The cost is high and this can be justified if the scale of the environment is big."
"It has a module-based pricing model."
"Licensing is based on the retention period of logs and metrics."
"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."
"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."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"The tool is very pricey."
