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

"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 alerting capabilities of AlertSite were really helpful."

"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."

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

"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."

"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."

"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."

More AlertSite pros

"This is purely an application instrumentation and monitoring tool with good features for business analytics."

"One thing we like about AppDynamics is the fact that you get the end-to-end topology right out the gate, with very little configuration, so right when you start up a new application it's automatically reporting and you can get deeper dives without having in-depth knowledge of your application because it automatically makes those connections for you."

"Splunk AppDynamics positively impacts our organization by allowing real-time performance monitoring, enabling us to optimize various business applications and visibly enhance their performance."

"We decided to invest in AppDynamics because we wanted to move from being reactionary to being proactive, that's really what it comes down to."

"We are able to correlate performance between tiers."

"APM really helps us in getting down to the bottom of these sorts of workloads; how code responds to these sorts of workloads and how we can make our application deliver better latency and a better end-user experience."

"The solution helps us provide a better user experience to our customers."

"With Splunk AppDynamics SecureApp solution, we can easily see our application's vulnerabilities, attacks, and exploits in real time."

More Splunk AppDynamics pros

Cons

"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."

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

"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."

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

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

"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."

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

More AlertSite cons

"The product's drawback is the licensing pricing. It could be better."

"At this time, we don't have much visibility on the virtual environment, monitoring, and all other things."

"One of the things that we would like to improve a little more is the dashboards. The dashboards are good, but I believe that they could improve even more."

"The product has a pretty diverse metrics browser, but I’d like to see better out-of-the-box visual reporting so that we can roll this up to management."

"The scalable of this solution is relative."

"The solution needs to support IBM products."

"The networking monitor function could be better, we are not getting many details from it."

"One thing that can be improved is the license structure."

More Splunk AppDynamics 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."

"AppDynamics Database Monitoring is expensive. I rate it a seven to eight out of ten."

"The tool is expensive."

"There were no added costs in addition to the standard licensing fees."

"AppDynamics is one of the most expensive solutions on the market."

"You are required to purchase licenses whether you use it or not. It is not pay-as-you-use."

"AppDynamics is an expensive solution."

"The licensing scheme is very complex. They need to make it easier."

"The pricing model for AppDynamics could be better. You have to subscribe to a yearly or a three-year licensing, which isn't very handy. The solution is one of the most expensive in the market today."
