Detailed observability has transformed agent monitoring and now detects hallucinations quickly
I think everything is there to be true. I do not think there is a scope for improvement in Arize AI. Everything is there. It has a steep learning curve. It takes time to see how Arize works. It is not a very basic thing where anyone can go and start doing it because it takes time. There is a steep learning curve for Arize AI. Because there are so many things in the model or in an agent, it takes time. It is not very easy to use, it takes time. It has a lot of advantages, but it takes time to learn how Arize works. As I mentioned earlier, it has a steep learning curve. It takes time to learn Arize AI, it takes time to configure, it takes time to create dashboards and monitors, and it takes time to understand the UI and determine what can I find where. It takes time to do all of that. It has a steep learning curve.

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.

Quotes from Members

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

Pros

"Arize AI, with its major features similar to those platforms, is a good alternative."
"Arize AI has positively impacted my organization as the answers are more accurate and agent quality has improved dramatically."
"Arize AI has made leadership more comfortable with introducing AI features by providing better visibility into failures and reducing unexpected issues in production."
"One of the major improvements is that prior to using Arize AI, our agent was hallucinating and we were not aware of when it hallucinates or we had a problem in debugging."
"Arize AI has positively impacted my organization by reducing most of our manual work, shifting us to complete automation, reducing working hours, and allowing us to focus more on accuracy with less chance of mistakes."
"Arize AI stands out to me because of its observability and traceability and ease of use; you can click and you are good to go, and it makes you catch bugs and issues very early before debugging while helping you monitor your models in production."
"In my day-to-day work, monitoring is the main focus, and while there are many other tools like Prometheus and Grafana for monitoring, for ML specific use cases, I think Arize AI is the best."
"Our timely actions, aided by Arize AI, have allowed us to report results with over 99% accuracy, proving it quite useful."
"Datadog was a way simpler solution to setting up browser and API tests quickly."
"It is easy to navigate the menu and create tests."
"Datadog has positively impacted my organization by allowing us to gather complete data instead of looking all over the place at incomplete data and actually make pointed determinations for fixing issues."
"Datadog helps us detect issues early on and helps in troubleshooting."
"The most valuable aspect of the solution is the APM."
"We also use APM and metrics to view the status of our Pub/Sub topics and queues, especially when dealing with undelivered messages."
"In terms of the public cloud provider integration of AWS, I would say it's very easy and straightforward to integrate."
"Synthetic testing has been a game-changer, allowing us to catch potential problems before they impact real users."
 

Cons

"More end-to-end architecture examples would be beneficial as current technical documentation is solid, but more practical examples are desired."
"I think we can improve its interface."
"The evaluation workflow lacks depth in comparison to competitors, which generally rely on traditional ML frameworks."
"I think Arize AI lacks some capabilities like a versioning system."
"It has a steep learning curve."
"Arize AI can add more functions."
"We mostly use Arize AI for the ML side, but in my experience, Arize AI lacks on the GenAI side."
"Graph filters for logs need to be set manually which works well for JSON but not for unstructured logs."
"Datadog's roadmap can be a bit unpredictable at times."
"I sometimes log in and see items changed, either in the UI or a feature enabled. To see it for the first time without proper communication can sometimes come as a shock."
"Datadog could be improved if the menu system was a little clearer and less cluttered, making it easier to navigate."
"I would like testing for data in the future."
"We have found that some of the different options for filtering for logs ingestion, APM traces and span ingestion, and RUM sessions vs replay settings can be hard to discover and tough to determine how to adjust and tweak for both optimal performance and monitoring as well as for billing within the console."
"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."
"At times, it can be hard to generate metrics out of logs."
 

Pricing and Cost Advice

Information not available
"Licensing is based on the retention period of logs and metrics."
"Our licensing fees are paid on a monthly basis."
"The solution's pricing depends on project volume."
"This solution is budget friendly."
"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."
"Sometimes it's very hard to project how much it will cost for the monthly subscription for the next month when you add certain features. Having better visibility of the cost would give a better experience."
"​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."
"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."
