Proactive monitoring has improved uptime and now detects performance issues before users suffer

The user interface and configuration experience could be more modern and streamlined in some areas, especially when managing a large number of monitors or creating complex monitoring workflows. Better navigation, integration, and more intuitive customizations for the dashboard and alerts would improve the overall operational experience. Dashboard customizations and reporting flexibility represent another improvement area. More advanced visualization options and an easier way to create tailored operational dashboards would help the team analyze trends and share insights more effectively. The integration ecosystem could also be expanded further, especially for modern DevOps and cloud-native workflows. Stronger native integrations with collaboration tools, observability platforms, and CI/CD pipelines would make it easier to fit into the evolving engineering environment. It would also help to have more automation-friendly capabilities such as easier API-based configurations, management, and infrastructure as code support for monitor provisioning. That would make large-scale monitoring management more efficient for the DevOps team. From a support perspective, the experience has been generally stable, but faster turnaround times for more complex technical issues and more detailed troubleshooting guidance would be beneficial. Improved documentation and more advanced implementation best practices for enterprise-scale deployment would also help the team onboard and optimize the platform more effectively. AlertSite would benefit from continued modernizations in a few areas. The biggest improvement would be a more intuitive and modern user experience for configuring monitoring, managing alerts, and navigating dashboards, especially in larger environments with many monitored services. Stronger integrations with modern cloud-native DevOps ecosystems including better automation support, richer APIs, and easy integration with CI/CD pipelines and observability platforms would also be helpful. Another improvement area is intelligent alert management. Features such as smart alert correlations, anomaly detections, and noise reduction would help operations teams focus on the most critical incidents more effectively.

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

"The return on investment of this solution is well witnessed in our organization because of the integration and various capabilities that it offers to interact with the upstream or downstream systems."

"This solution has numerous advantages; it's extremely simple to configure, and either digital monitors or single-URL monitors are simple to configure and build."

"The alerting capabilities of AlertSite were really helpful."

"I highly recommend AlertSite to other users."

"There are custom reports available along with the inbuilt reports."

"The best feature of AlertSite is that it shows you a visual graph and also sends you notifications about errors, so you get immediate notifications about errors which means that your support team can start taking steps and more quickly make sure the site is up and that customer experience isn't interrupted in terms of using your system and your products. AlertSite is a very good tool. It's user-friendly, and you can see everything on the dashboard. Configuring it is also easy."

"If there are any issues, it triggers an alert within 30 seconds. When it triggers the alert, we go ahead and check it immediately. The alert is triggered on a real-time basis."

"AlertSite has helped improve issue detection, reduce downtime risk, and support faster troubleshooting in the production environment."

More AlertSite pros

"Datadog has positively impacted our organization by allowing us to look at things such as Cloud Spend and make sure our services are running at an optimal performance level."

"While my team is relatively new to Datadog, I already see immense value in switching over to Datadog as the primary APM and NPM tool."

"It helps us better manage our logs."

"From the number of outages stopped or shortened (which lead to lost revenue from non-renewals) and the number of hours saved on investigations (which correlates to engineering salaries), I estimate that the ROI of the implementation time and monthly charges to be between 10x and 20x."

"Synthetic testing is by far the most valuable feature in our organization."

"Datadog has impacted our organization positively in a major way because not even just as a QA engineer having access to the real-time replay, but just as a team, all of us being able to access this data and see what parts of our system are causing the most errors or resulting in the most frustration with users."

"We rely heavily on the API crawlers that Datadog uses for cloud integrations. These allow us to pick up and leverage the tags teams have already deployed without having also to make them add them at the agent level."

"Anything I've wanted to do, I found a way to get it done through Datadog."

More Datadog pros

Cons

"In terms of support, it is all based on the cost of the subscription that our company purchased, but it wasn't great, and it could've been much better."

"The user interface and configuration experience could be more modern and streamlined in some areas, especially when managing a large number of monitors or creating complex monitoring workflows."

"AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed."

"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."

"I would like the ability to get more data points with regard to some of the unique requirements that we have."

"One area that needs improvement in AlertSite is the slow UI. I'm using the classic UI because it's quite user-friendly, or in human-readable format, but it's a little slow. It takes time to load all the monitors, so if that could be sped up, that would be helpful. The AlertSite support team also needs improvement in terms of availability. Most of the agents in the team aren't available 24 x 7, so if there's something you need to discuss, you need to tell the support team ahead of time to schedule it. Multiple times, when a case comes up during weekends or whenever my team is doing an update, support needs improvement, availability-wise. I use AlertSite for synthetic monitoring, so whatever is available right now is okay, but if I want to request a new feature on a website, currently, the UI refreshes automatically. I would like to have the option on AlertSite to configure that manually. The UI auto-updates every few minutes, so if I can control that manually, that would be helpful."

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation. If there's a specific activity you want to do, you can't even find information on how to do it, so you have to contact the AlertSite support team to assist you, and only then would the issue be resolved. At the moment, it's not easy to find or get full documentation on how to deal with different issues. You always have to go back to AlertSite support and get help. The documentation for AlertSite could be improved and it's what I'd like to see in the next release of the tool because at the moment, the documentation isn't complete, so you'll have to contact support, but contacting support isn't an issue because the team responds to you quickly."

More AlertSite cons

"When I started using it years ago, it had stability problems. I remember, specifically, we ran everything in Docker containers. There were some problems getting it into a Docker container with very specific memory limits."

"The setup was a bit complex."

"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."

"The pricing model can be quite complex and might benefit from more flexible options tailored to different organizational needs."

"They can cut down the prices for Cloud SIEM. It seems very useful, however, the prices are high."

"ECS could be improved by including more tutorials for beginners to reduce the barriers to entry."

"The product can be improved by allowing the grouping of APIs to add variables. That way, any API with a unique ID could be grouped together."

"Datadog is a platform that can be improved by making its pricing more predictable, as sometimes it is difficult to forecast exactly how much a new project will cost until after we have started ingesting the data."

More Datadog cons

Pricing and Cost Advice

"The cost is high."

"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."

"We purchased the license once and had the option of selecting the number of user licenses."

"It costs the same amount it would if we were hosting it ourselves, so we are incredibly happy with the cost."

"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."

"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."

"While it is an expensive product, I would rate the pricing level at four out of five."

"It didn't scale well from the cost perspective. We had a custom package deal."

"The price is better than some competing products."

"The solution's pricing depends on project volume."

"The tool is open-source."
