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 monitoring has improved our banking API performance and supports detailed business transaction analysis

The real-time monitoring is what we can see for anything that is needed in terms of CPU, memory, or the connections or the sessions related. It's real-time monitoring of performance of each of the components, which is what we need and use all the time. It's highly effective, I would say. Infrastructure visibility, transaction monitoring, to check the actual user experience in terms of the response time, MRT and all those things. We do the component monitoring like the API performance and the connections and all those things, but we also do the business process monitoring and business transaction monitoring.

Quotes from Members

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

Pros

"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."

"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."

"The alerting capabilities of AlertSite were really helpful."

"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."

"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

"The ability to check parameters for microservice applications is most valuable. It is important for me. I can manually create new business transactions for applications and individually monitor business transactions. I can also use a lot of extensions. It has a lot of extensions to monitor other third-party applications, such as NoSQL applications, memory cache applications, Kafka applications, and Couchbase applications. It is very useful. We are also using the end-user monitoring site to follow all end-user activities. It is important for us to check the errors on the customer site."

"We have been able to monitor our applications more accurately."

"AppDynamics' best feature is automation - for example, when I add a note, it can understand the data automatically."

"Once you use AppDynamics it feels like you were standing in the dark before."

"The most valuable feature of the solution is its GUI."

"We have a really close relationship and technical support is really one of the best on the market."

"I think the performance and interface are the most important features."

"Splunk AppDynamics has positively impacted my organization substantially because most of the critical applications within our organization are monitored through Splunk AppDynamics for application performance monitoring."

More Splunk AppDynamics 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."

"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."

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

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

"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."

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

"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."

More AlertSite cons

"The monitoring capability could be improved; it does have a monitoring capability, but it's very, very basic."

"Application Analytics' performance in pure and native cloud environments could be improved."

"The initial setup could be easier."

"AppD is really cool and a unified solution for both APM and APM centric analytics side, but this process is a little bit manual."

"Specific to what our experience is, because we're using Cloud Foundry, we're using an extension to monitor the infrastructure for that; that's probably the weakest point for it, because it basically collects JMX metrics."

"The pricing falls within the mid-range category."

"I have seen many good aspects of the product and many advantages, while also identifying areas for improvement or concerns with the product."

"AppDynamics Database Monitoring would be a better product if it could support new technology, such as cloud technology. Even Dynatrace lacks support for newer technologies."

More Splunk AppDynamics cons

Pricing and Cost Advice

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

"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 are looking forward to purchasing the solution on the AWS Marketplace."

"AppDynamics is an expensive solution."

"AppDynamics Browser Real-User Monitoring does have licensing cost associated with it."

"In terms of pricing, I feel that when you compare the benefits that we get to the price that we paid, it is reasonable."

"AppDynamics Server Monitoring is an expensive solution."

"This solution is not the cheapest but it works well. You will end up doing more work with a cheaper solution than if you just spent the extra money on a better solution like this one."

"The license fee for Application Analytics is in the range of 2.5 million over three years, with extra fees for service contingencies."

"AppDynamics does not usually do monthly payments. They do it on an annual basis, at the very least."
