Enterprise-level monitoring facilitates global observability and seamless script creation with intuitive tools
SmartBear, as a vendor, is focusing more on API management and testing rather than monitoring. AlertSite could benefit from more future-focused innovation, especially with competencies in generative AI. Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7. Outside of critical platform issues, there's no continuous support available.

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."
"There are custom reports available along with the inbuilt reports."
"The alerting capabilities were really helpful."
"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."
"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"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."
"I highly recommend AlertSite to other users."
"The most valuable feature in AppDynamics is the identifying of the slow responses. Additionally, it is easy to use."
"Immediately allows you to see the relationships between the different nodes."
"The most valuable feature of AppDynamics is Proactive Monitoring and Alerting."
"The most valuable feature is the live reporting on the current health\performance of our application"
"It gives me the ability to trace logs between transactions, for example, a DB transaction or JVM transaction from one hub to the other, so I can easily find out where the problem is or where the bottleneck of the issues lies."
"It is used to test customer behavior on a website."
"The features, ease of use, and customer service provided by AppDynamics was what tipped the scale towards them."
"You have a live view of what happens when something goes wrong on the production or support side. You don't have to scramble and do guesswork. We can identify the query that creates the bottleneck or slows the performance of the database system. It can give you points on how to debug and fix the system."
 

Cons

"AlertSite requires improvements related to security, even at the enterprise level."
"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"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."
"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."
"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."
"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 cost element is an issue. I can't expect the company to change its way of work. However, given the fact that we earn and do all our business in South African Rand, I would prefer to buy in Rand as opposed to the American dollar or British pound."
"The synthetic scripting for end-user monitoring could be a little bit broader."
"Regarding Search Guard functionality, there is room for improvement."
"Installation and configuration can be very tough. An average user without specialized knowledge can't do this. You need to have DevOps and QA teams handle it. During installation, a lot of customers get stuck trying to track the database or the API part, and they have to contact customer support."
"AppDynamics Database Monitoring would be a better product if it could support new technology, such as cloud technology."
"In the current version of AppDynamics, there is a correlated section, where we can see all servers’ performance along with application performance, but network performance is missing."
"The tool should provide information like the number of connections and processes utilized in real time."
"It is stable, but the only downside is the licensing part."
 

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."
"It does require licensing to be paid."
"I rate AppDynamics Mobile Real-User Monitoring's pricing as seven out of ten. Mobile monitoring is paid based on the number of instances utilizing the mobile monitoring service, which increases as the scale grows. Consequently, your mobile user count can proportionally surpass all other applications."
"It is expensive. However, our time to recover has been reduced, and this product has helped recuperate costs and provided us with ROI."
"AppDynamics Server Monitoring is an expensive solution."
"We have two different licensing models for this solution. One of them is the agent based model, which requires payment per agent. The other is an infrastructure based model, where the price is based on the CPU core. For the infrastructure model wholesale level pricing applies. All of the up to date licensing prices for this product are available on the manufacturers website."
"AppDynamics Server Monitoring is a very expensive product, but if you negotiate well, you get value for money...My company used to make early payments toward the licensing costs of the solution, but now my company has opted for a different licensing model."
"As compared to other applications, its price is moderate. Its price is neither very high nor very low."
"The pricing needs to come down."
