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.

Helps reduce response time but has room to improve customization complexity

We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Quotes from Members

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

Pros

"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."

"I highly recommend AlertSite to other users."

"The alerting capabilities of AlertSite were really helpful."

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

"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."

"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."

"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 solution is completely open-source, so it is quite affordable."

"The most valuable feature is the support for monitoring Cisco switches."

"The solution is quite mature and very stable."

"It has good graphs of what is going on within the operating system."

"Dashboard and the customization of the items and triggers are the most valuable features."

"The template system in Zabbix is very beneficial as it saves time in configuration."

"The flexibility of taking monitoring data from such a wide variety of platforms - beyond traditional IT - makes Zabbix a highly flexible solution."

"The initial setup was very quick. The first time it was long because I didn't know it yet. I was only using Windows. The first time was very difficult because of the operating system."

More Zabbix pros

Cons

"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."

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

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

"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."

"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."

"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."

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

More AlertSite cons

"The user interface could be a bit better. They could update it a bit."

"We had some scalability issues with a large number of nodes."

"The initial setup could be complex if you don't have templates. If creating templates from scratch, it's quite difficult, but if you are using already pre-created templates and setups for your needs, it looks very good."

"It hasn't really been that stable, but I think that has a lot to do with the specs. It could be more stable."

"The integration of the product is not so easy, especially when it comes to the application database."

"The low discovery functionality is still very young so this feature has a lot of room for improvement."

"Sometimes, the documentation is a little bit written in Estonia – a country in Europe. The language barrier and translation to English can sometimes make it difficult to understand what they're trying to get at. It's just a language thing."

"The only issue I can note is that it's Linux-based, and Linux documentation is not the best."

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."

"The tool's licensing costs are yearly."

"This solution is completely open-source, so it is quite affordable."

"Zabbix and Grafana are both open source products, we only needed to go to their website and download the application and we began to use them. The solutions are free."

"It is worth every cent to pay or even study to do your own installation."

"It's free software released under the GNU/GPL license."

"My manager is very happy because it doesn't cost anything."

"For pricing, it's free. We don't pay anything for it. They open-source the code, and people pay for support."

"If you have 20,000 hosts, the support costs around €95,000 for a year."
