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

"It brings in observability, monitoring, and alerting capabilities - all of which we need to operate at scale."
"Our ROI with Datadog has been very high."
"The dashboards provide a comprehensive and visually intuitive way to monitor all our key data points in real-time, making it easier to spot trends and potential issues."
"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)."
"For us to have visibility into our app stack and the hardware we run has been highly beneficial."
"The most valuable aspect for us is to have everything in the same place."
"Datadog will positively impact my organization by allowing me to handle ticket resolutions at a much faster pace and bring productivity by reducing the number of support engineers required at the monitoring level."
"The ease of dashboard creation and alarm monitoring has helped us not only stay competitive but be industry leaders in performance."
"The score-based application performance ratings help the network team."
 

Cons

"Auto instrumentation on tracing has not been very easy to find in the documentation."
"I believe there is room for improvement with this solution. It wasn't easy for me to get a quick understanding of what this tool offers us as opposed to the added tools of AWS."
"At times, it can be hard to generate metrics out of logs."
"​It would be nice to be able to graph metrics by excluding certain tags (like you can do in monitors)."
"Alerting timing should be improved to be more fine-tuned and exact."
"Datadog probably didn't save me a ton of time because there are so many replay videos that I had to sort through in order to find the particular sales reps that I'm looking for for our beta test group."
"The cost is pretty high."
"They could have better log reporting."
"The product must start using a bit more machine learning and AI, especially for security."
 

Pricing and Cost Advice

"It is easy to run up a large bill, so become familiar with the cost of each piece of your bill and use the metrics they supply to estimate and monitor your bill."
"At my last company, we did see ROI, specifically around response time. We could get to mission critical things that were down and losing revenue on immediately. So, the product paid itself back."
"The pricing came up a bit compared to their competitors. It is not that the price has risen, but that the competitors have gone down. They keep adding more features that I would have expected to be baked in at a more nominal price. I have been increasingly dissatisfied with the pricing, but not enough to jump ship."
"It costs the same amount it would if we were hosting it ourselves, so we are incredibly happy with the cost."
"​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."
"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."
"Licensing is based on the retention period of logs and metrics."
"While it is an expensive product, I would rate the pricing level at four out of five."
"The tool is very pricey."
