Featured Reviews

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.

Tracking model metrics and artifacts has improved workflows but documentation needs clarity
In my opinion, the best features Weights & Biases offers are that they are easy to adapt and navigate through inside their UI, and I can check the model artifacts by versions. Sometimes when it throws errors, I can check them easily, and it has access control that's a good fit for corporate usage. What I like about the UI and the access control features is that they are just easy to navigate, easy to understand, and finding is also easy. Weights & Biases has positively impacted my organization a lot because many users are using Weights & Biases for tracking models and seeing metrics. I believe it places a lot less weight on setting up this tracking method. I can share specific outcomes or metrics since using Weights & Biases. For example, I can check each epoch's model artifacts and see how effectively it worked on my evaluation set, and it can be fetched by the unique ID.
