In AlertSite, I was monitoring the kiosks and servers for JetBlue Airlines. The servers would trigger alerts if there were any outages or issues with any of the kiosks, servers, or the ticketing tool. I monitored these alerts and escalated them to the concerned team to rectify them at the earliest…

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.

Room for Improvement

AlertSite's reporting capabilities and private locations need enhancement. Support and documentation require improvements due to limited availability and incompleteness. Security concerns, particularly regarding recent findings, demand attention. Automation struggles with some platform compatibility. Improvements in alert customization and UI speed are necessary. Users report false alerts and limited UI options. The platform's focus on API management is perceived as lacking in monitoring innovation. Enterprises require more consistent and readily available support.

"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"I could use a few changes to the user interface."

ROI

AlertSite has proven to be a valuable investment for organizations, thanks to its integration and wide range of capabilities. It allows users to effectively interact with both upstream and downstream systems. By serving as a proactive indicator for priority-one or severity-one incidents, it helps users address issues before they become major problems.

Pricing

Enterprise buyers found AlertSite's licensing options offer flexibility, allowing selection of user licenses and annual contracts. Although costs can be considered high by some, this varies based on the number of monitors needed. Management typically oversees licensing and cost decisions. Many users rated AlertSite's pricing favorably, considering it reasonable or assigning a high satisfaction score. This feedback indicates a generally positive perception about pricing among users.

"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."

Popular Use Cases

AlertSite is used primarily for monitoring cloud applications, URL and multistep transactions, portals, intranets, and airline profiles. Users monitor availability, latency, login functions, failures, and more through synthetic checks, URL checks, TCP connections, and API monitoring. AlertSite's Deja-Click feature creates recordings to detect UI changes and alerts teams of downtime or issues, integrating SaaS locations or private node servers for internal network management.

Service and Support

Customer service and support for AlertSite can be challenging at times, with some issues going unaddressed. Users appreciate documentation, although it's not fully updated. Support response time is quick on weekdays but slower on weekends, requiring scheduling for updates. Technical assistance is rated positively, though not available around the clock, as the team is US-based. Many reach out initially for scripting and functionality guidance, while others need help for unique issues.

Deployment

AlertSite's initial setup is generally straightforward and user-friendly. While some technical knowledge or documents may be needed, it can typically be managed by an intermediate person. The process duration varies, from a few minutes for a single monitor to a couple of days if coordinating with different teams. Some setups were completed swiftly with support team assistance. Tools like the DejaClick Recorder make creating scripts easier, and API integration further simplifies monitor setup.

Scalability

AlertSite demonstrates strong scalability, excelling particularly in the SaaS environment where management is seamless. On-premise infrastructure presents some challenges requiring capacity benchmarks, but adding users is straightforward. Companies find it easy to scale, managing varying hardware demands without issue. The scalability is generally rated high, often scoring between eight and nine out of ten. AlertSite effectively supports teams and users, accommodating expansion needs efficiently within diverse setups.

Stability

Users agree AlertSite is stable and performs well as a platform. Most find it reliable, with minimal downtime in recent years. Some users see potential improvements in application-level performance and support, but many prioritize its steady performance for SaaS locations and on-premise setups. Ratings range from eight to nine out of ten, reflecting confidence in its reliability.
