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.

Great for visibility but lacks many features and difficult to update

We're customers. We don't have a special relationship with the company. I am the operation's application administrator. At the moment, the solution is monitoring the applications that we want it to monitor. We're not looking at it on a daily basis. We just use it here and there. The challenge we have is that we believe that Dynatrace can address some tasks we'd like done that are not possible to execute on this solution. Dynatrace includes monitoring of not just the logs, but the applications as well. Dynatrace also makes us include firewalls, etc. We could have it so there are end to end solutions or identifications within the process. What we have right now is only the app server as well as the database server and its connectivity. The solution does save time that's caused when creating SQL coding. However, there are some issues around AppInternals changing the code and giving us issues. From the point of view of the top management, we want a more permanent solution. We want to identify what causes issues and we are looking for a more end-to-end solution. That is why we are looking at Dynatrace. I don't know if I have any advice for other organizations. The experience I have is only based on my own limited experience. However, I believe that the application has the potential to be really good if it identifies what is really important to an organization. It's still sort of half-baked without AppResponse. Without the other key features in infrastructure, like the network, firewalls, and proxies, it's lacking. It's not fully complete. I'd rate the solution six out of ten. It addresses some of our needs, but there's a lot lacking that could be added to make it a fuller, more interesting product.

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 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."

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

"The alerting capabilities of AlertSite were really helpful."

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

"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."

More AlertSite pros

"The capability of analysing each individual transaction captured to a very low level detail (method call/line of code)."

"Many times what might have taken hours or days can be resolved in a few minutes."

"From the experience I had with these three tools, I realized that Riverbed was superior in all aspects (performance, user experience, and features)."

"I like it that one can match IPs with the application name."

"Mean time to isolate a problem has dropped by 50-75% in each region since we've deployed the Riverbed SteelCentral suite."

"Browsermetrix, which is real-user monitoring via JS injection and linked back to TTW via cookie. It allows us to see the experience of every user hitting our sites and analyze performance by region, browser, etc."

"Synthetic transactions, WMI and SNMP query capability."

"The most valuable aspect of this solution is the integration with their other systems. It's easy to understand and it points out the relevant problems in the enterprise."

Cons

"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."

"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."

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

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

"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."

"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."

"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

"Support for PHP, DB and other applications need to be supported."

"It's still sort of half-baked without AppResponse. Without the other key features in infrastructure, like the network, firewalls, and proxies, it's lacking."

"They should find a way for report generation from TTW to run quicker."

"The admin dashboard could be easier as it takes a little bit of time to get used to it."

"The recording mechanism for synthetic transactions could be improved as well."

"The technical support is not very good and should be improved."

"I would like for it to have automated updates, the way the product updates itself should be all automated, as opposed to what it is now."

"We'd like to be able to find out performance problems on application class and methods."

Pricing and Cost Advice

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

"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."

"The licensing model is expensive compared to its competitors, but the service it gives to your business, and the data quality, means that it's worth it."

"The licensing model for v9 is better where it is an individual license per server, while v10 licenses are per JVM/ .NET and server instance. The latter model appears to be the model that other APM vendors are using."
