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.

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.

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 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."
"Arize AI has made leadership more comfortable with introducing AI features by providing better visibility into failures and reducing unexpected issues in production."
"Our timely actions, aided by Arize AI, have allowed us to report results with over 99% accuracy, proving it quite useful."
"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."
"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 as the answers are more accurate and agent quality has improved dramatically."
"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."
"Monitoring has been invaluable, and as we start to look to other products, bringing in logs and APM traces will create a full picture of what we need to do to resolve incidents."
"Datadog has flexibility."
"I find the greatest feature is being able to search across logs from various microservices."
"The feature I've found most valuable is the log search feature."
"Session recordings have been the most valuable to me as it helps me gain insights into user behaviour at scale."
"Datadog has positively impacted my organization by shortening our time to resolve incidents because it's a central place for getting all the data that we need for troubleshooting."
"One of the solution's greatest aspects is its overall simplicity; it is very easy to use and easier to handle than other brands we have access to."
"Overall, it has improved operational efficiency and reduced downtime by enabling quicker responses during incidents."
 

Cons

"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."
"I think we can improve its interface."
"More end-to-end architecture examples would be beneficial as current technical documentation is solid, but more practical examples are desired."
"I think Arize AI lacks some capabilities like a versioning system."
"The evaluation workflow lacks depth in comparison to competitors, which generally rely on traditional ML frameworks."
"It has a steep learning curve."
"Datadog lacks a deeper application-level insight. Their competitors had eclipsed them in offering ET functionality that was important to us. That's why we stopped using it and switched to New Relic. Datadog's price is also high."
"For some features, it was quite expensive. For example, APM and RAM, and Session Replays."
"I spent longer than I should have figuring out how to correlate logs to traces, mostly related to environmental variables."
"ECS could be improved by including more tutorials for beginners to reduce the barriers to entry."
"It could use some additional features when working with metrics like Grafana or like New Relic has. Datadog does not use library technologies like Dynatrace does. Datadog has machine learning too, but it does not have this option in all layers of monitoring like infrastructure service process in applications."
"We would really like to see more from the Service Catalog."
"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."
"We need a lot of modules since we collect all data logs from all operating systems."
 

Pricing and Cost Advice

Information not available
"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."
"Pricing and licensing are reasonable for what they give you. You get the first five hosts free, which is fun to play around with. Then it's about four dollars a month per host, which is very affordable for what you get out of it. We have a lot of hosts that we put a lot of custom metrics into, and every host gives you an allowance for the number of custom metrics."
"This solution is budget friendly."
"Our licensing fees are paid on a monthly basis."
"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."
"It has a module-based pricing model."
"While it is an expensive product, I would rate the pricing level at four out of five."
"The tool is open-source."
