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.

Alerting improves incident response across teams and enables faster awareness before customer impact
Splunk Observability Cloud could be improved in terms of integrations with more technical add-ons, such as Zoom. Although they have one with Zoom, it's not available in the cloud, so having that feature would be beneficial. Essentially, Splunk should continue expanding to create easier ways to ingest logs from different products. The out-of-the-box customizable dashboards in Splunk Observability Cloud are very effective in showcasing IT performance to business leaders. However, there are aspects that could be improved, such as linking dashboards to one another. While IT leaders may not drill down, it's crucial to create levels of dashboards for technical users to find root causes, making it effective for stakeholders.

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."
"If there are any issues, it triggers an alert within 30 seconds."
"There are custom reports available along with the inbuilt reports."
"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"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 were really helpful."
"The alerting capabilities of AlertSite were really helpful."
"I highly recommend AlertSite to other users."
"This solution is very quick to deploy as it is a SaaS solution and integrates with tools like ServiceNow."
"The solution has significantly helped improve my operational performance and my company's resilience by providing real-time insights."
"It has been beneficial for our IT infrastructure."
"The most valuable features include user time tracking and the ability to analyze application load times."
"The most valuable feature is the ability to customize dashboards based on my queries or any other customization I may need."
"Splunk Observability Cloud has optimized our solutions and helped us understand the metrics."
"The features are pretty much ready out of the box."
"The most valuable feature is dashboard creation."
 

Cons

"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."
"AlertSite requires improvements related to security, even at the enterprise level."
"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."
"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."
"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."
"I could use a few changes to the user interface."
"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 dashboards are used mainly to visualize information about the infrastructure, but it isn't easy to construct or use the dashboards. While we tried to resolve the issue by calling support, it would be easier if they had an AI co-pilot to identify the problem and help you solve it."
"Splunk Observability Cloud has not yet completely improved our operational performance for our company's resilience as we are just starting out, however, it will help us ultimately to reduce incident time."
"The security could be better."
"There's no standard use case available where you can see the utilization of the number of use cases I have."
"Unfortunately, with our current setup, we just have to implement Log Observer in a couple of instances so that we can have that integration with Splunk Observability Cloud."
"The integrations need to be improved for Splunk Observability Cloud."
"It is essential for the monitoring tool to deliver quick response times when generating analytical reports, instead of prolonged delays."
"Splunk Observability Cloud could be improved with better integration with AppDynamics, as we know that's coming, however, it is an issue we've had between the OpenTelemetry and the AppDynamics collector."
 

Pricing and Cost Advice

"The cost is high."
"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."
"I am not in that circle, but we are currently licensing based on our queries. That is working out for us. Previously, it was by volume of data, and now, we can store as much data as we want."
"Splunk's infrastructure monitoring costs can be high because our billing is based on data volume measured in terabytes, rather than the number of devices being monitored."
"Splunk has been fairly expensive, but it has been predictable."
"Splunk Infrastructure Monitoring is an expensive solution."
"Splunk APM is expensive."
"The solution's pricing is competitive. I rate the solution's pricing a seven out of ten. The price of the solution could be cheaper."
"The pricing is reasonable."
"Splunk APM is a very cost-efficient solution."
