Kallamuddin Ansari - PeerSpot reviewer
Cyber Security Consultant at HR Software Solution
Unified monitoring has improved incident response and now reduces root cause analysis time
One area where Datadog can be improved is around alert quality. In the beginning, it tends to generate many alerts, and without proper tuning, many of them are not actionable. It would help if there were more built-in guidance or smarter defaults to reduce noise. Another improvement area is cost visibility and control. As log and metric ingestion increases, it has not always been straightforward to track which data is driving the cost. More granular and real-time cost insights would make it easier to manage. Additionally, while the dashboards are flexible, navigating and organizing them at scale can become slightly difficult. Better structuring or management options would help in larger environments.

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

"The seamless integration between Datadog and hundreds of apps makes onboarding new products and teams a breeze."
"Features-wise, I'd give them a rating of ten out of ten."
"Integrating Datadog with other platforms has made our monitoring processes a bit easier. It's not super simple, but it's manageable."
"Being able to filter requests by latency is invaluable, as it provides immediate insight into which endpoints require further analysis and optimization."
"Log analytics give us a powerful mechanism for error tracking, research, and analysis."
"It brings in observability, monitoring, and alerting capabilities - all of which we need to operate at scale."
"I don't have to worry about upgrades with the AWS version."
"The APM has made observability and tracing more accessible to developers."
"The score-based application performance ratings help the network team."
 

Cons

"We did have an issue where a synthetic test was set up before the holiday break, and we were quickly charged a great amount. Our team worked with Datadog, and they were able to help us out since it was inadvertent on our end and was a user error."
"The sheer amount of products that are included can be overwhelming."
"While it’s powerful, the interface can feel cluttered and overwhelming for new users."
"I've found that the documentation is lacking in certain regards."
"The pricing should be less of a surprise."
"One key improvement we would like to see in a future Datadog release is the inclusion of certain metrics that are currently unavailable. Specifically, the ability to monitor CPU and memory utilization of AWS-managed Airflow workers, schedulers, and web servers would be highly beneficial for our organization."
"There is occasional UI slowness and bugs."
"The documentation leaves a lot to be desired for new users."
"The product must start using a bit more machine learning and AI, especially for security."
 

Pricing and Cost Advice

"The solution is fairly priced but history and log storage can get costly depending on your needs."
"The price of Datadog is reasonable. Other solutions are more expensive, such as AppDynamics."
"​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."
"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 a module-based pricing model."
"The cost is high and this can be justified if the scale of the environment is big."
"Licensing is based on the retention period of logs and metrics."
"It costs the same amount it would if we were hosting it ourselves, so we are incredibly happy with the cost."
"The tool is very pricey."
