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.

The installation process is the first aspect I dislike about Splunk ITSI (IT Service Intelligence). If you do not configure it correctly, you will encounter issues in the search head. Because we use a distributed environment where each component has its own specific roles, installation is critical and requires careful attention. Splunk ITSI (IT Service Intelligence) is built with many applications. It is a compressed file, and when you extract the Splunk ITSI (IT Service Intelligence) app, you receive approximately 19 apps. Some applications, add-ons, and packages must be installed on specific components. If you do not configure an application correctly, it will not work. Sometimes we encounter issues during installation because of this complexity. I believe the installation process should be more uniform, meaning it could be deployed across all components to avoid post-installation issues. Sometimes after installation, you receive errors, and users cannot access Splunk ITSI (IT Service Intelligence). We have experienced this type of issue due to installation errors. I believe there is currently room for improvement regarding scalability. When we create Glass Tables containing many searches, the Glass Tables sometimes fail due to memory constraints, and we receive error pages. Splunk ITSI (IT Service Intelligence) should have a lightweight version to address these concerns. I would rate current scalability as medium.

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."

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

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

"If there are any issues, it triggers an alert within 30 seconds."

"I highly recommend AlertSite to other users."

"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."

"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."

"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

"Customers have noted the solution helps streamline incident management."

"The solution's scalability is fine."

"The feature that stood out to me most from Splunk IT Service Intelligence (ITSI) was automated dashboarding or reporting. The solution lists the severity level of issues, and the response times."

"In my opinion, Splunk IT Service Intelligence (ITSI) is better than QRadar. With the help of Splunk, we can get results."

"Splunk ITSI (IT Service Intelligence) positively impacts my organization by predicting many failures beforehand, helping us save money and preventing business disruptions by allowing us to address issues early."

"The best features of Splunk ITSI (IT Service Intelligence) are the APM, the Application Performance Monitoring, and the diagnostic capabilities; it is state-of-the-art."

"Overall, it's a very stable product."

"With Splunk ITSI (IT Service Intelligence), all alerts feed into one tool, providing rich dashboards and visualizations for our team to look at, making it a standout feature."

More Splunk ITSI (IT Service Intelligence) pros

Cons

"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."

"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."

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

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

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

"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."

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

More AlertSite cons

"They should make it easier to use. Many people are new to it. It is hard and has a steep learning curve."

"ITSI could benefit from a security model that would allow operations team members to get involved in model building, KPI implementation, and model maintenance, while maintaining appropriate segregation of duties."

"The user interface visualization could be improved."

"I believe the refresh time should be faster."

"If they can somehow integrate it with AI in the near future, it will definitely be a game changer."

"While integrating services and KPIs in ITSI is straightforward, I found it challenging to analyze them with the service analyzers; specifically, using the deep dive feature to pinpoint the exact source and time of an issue proved difficult."

"There should be entity conflict resolution, specifically regarding duplicate entities. There should be case sensitivity for various keys amongst entities, specifically host names. We need IT metrics-based indexes and more content packs. I know they are coming out with these features"

"Splunk ITSI could benefit from including more features that other solutions support, such as vulnerability management modules."

Pricing and Cost Advice

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

"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."

"Splunk ITSI is a pay-per-use service that is priced fairly based on the amount of data we use."

"Splunk ITSI is expensive compared to other tools."

"It is interesting. I am not involved that much lately, but if I recall correctly, you license primarily on the volume of data that you are using in Splunk ITSI, but there is no way Splunk can ever check if that is true, so that is interesting. We are not doing it, but someone can pretend to just use 10%, and it would be super cheap. It is tricky, but it is more tricky for Splunk than for us."

"Splunk ITSI is expensive; however, with the appropriate use case, it justifies the cost."

"Splunk ITSI is an expensive tool, and we need to purchase the utility license."

"Pricing was pretty good, and it is possible to just add on the features we want."

"Its pricing has been changed as per the market. You get a good support service with it as well. They have 24/7 customer support. There is a portal, and if you are having issues, they are available in order to resolve them. So, its pricing isn't too much."

"Splunk ITSI is expensive."
