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.

Real-time error tracking assists the QA team in swiftly identifying and reporting bugs

One of the greatest advantages of Sentry is its support for Azure Web Services, which New Relic does not support. Sentry integrates with common developer communication platforms like Discord and WhatsApp, which allows developers to easily track notifications and findings in the applications. Real-time error tracking helps our Quality Assurance team easily identify the root causes of problems or bugs and promptly inform the developers about specific issues.

Quotes from Members

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

Pros

"I highly recommend AlertSite to other users."

"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."

"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."

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

"My company went with AlertSite because as a tool, it's fast, easy to maintain, and provides great support."

"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."

More AlertSite pros

"Sentry breaks everything down in real time."

"Its initial setup process is relatively straightforward."

"Sentry is a pretty stable product... Sentry's documentation is pretty straightforward and neat."

"Overall, I give Sentry a rating of 10."

"Sentry's performance monitoring has helped us understand where the bottlenecks are in our application and allowed us to optimize critical transactions for a faster user experience."

"Sentry provides excellent security when it comes to tables and databases."

"The most valuable feature is the ability to create and assign rules and give access to particular users."

"The most valuable feature we have found with Sentry is the security that it provides."

More Sentry pros

Cons

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

"It is not compatible with all of the product platforms that we use."

"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. 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."

"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."

More AlertSite cons

"I would like to see the ability to customize events and get more metrics for these customized events."

"We cannot restrict particular columns on particular data. It would be helpful if that feature was improved."

"The log centralization and analysis could be improved in Sentry."

"I would like to have alert policies and alert conditions enhanced in the next release."

"Lacks user metric tracking and the ability to create more dashboards."

"It would be nice if the product provided a map showing the users’ geographic location."

"Its debugging feature needs to be faster."

"The settings for an administrator are complex."

More Sentry 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."

"I am currently using a self-hosted open version."

"Currently, we are in the production phase of our project and we are on free plans to use Sentry. Once we go live we will have to be on a subscription-based plan."

"We can adjust the price a little bit based on our needs."

"We are currently paying through Cloudera for the Sentry service."
