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

"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."

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

"I highly recommend AlertSite to other users."

"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."

"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."

"I found multiple features in AlertSite that I like. One is data monitoring history, for example, a history of the blackouts and the data. Sometimes, there's a glitch in the application that AlertSite can capture, and the tool notifies you about that glitch. It also identifies issues that could happen in the future. AlertSite is also a fast tool that you can use to monitor on-premise servers, internal applications, and even global applications. The data is available on a single UI in AlertSite, so there's no need to monitor and click on different applications or URLs. I also love that the tool is quite user-friendly, apart from being fast."

More AlertSite pros

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

"We find the feature of cause-stack information integrated with the Git repository valuable, which provides contextual information."

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

"Sentry breaks everything down in real time."

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

"I would rate the stability of Sentry as eight out of ten."

"Sentry allowed us to be more proactive and also enhance your app's observability, and its native integrations with JIRA and Slack saved us precious time."

"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."

More Sentry pros

Cons

"I could use a few changes to the user interface."

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

"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."

"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."

"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."

"AlertSite requires improvements related to security, even at the enterprise level."

More AlertSite cons

"Its debugging feature needs to be faster."

"The settings for an administrator are complex."

"The integration could be improved, and the price could be lowered."

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

"It should be easier to integrate Sentry with other tools, and the end-to-end tracing capabilities could be improved."

"One area where I think Sentry can improve is in the granularity of its alerting system, as it sometimes feels too sensitive or not customizable enough."

"Sentry is more like an application mind trying APM platforms as opposed to also tracking analytics and things like that."

"I have not worked with Sentry long enough to provide advice for improvements. I need more experience and time."

More Sentry cons

Pricing and Cost Advice

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

"The cost is high."

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

"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."

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

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

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