Alerting capabilities have enabled timely escalation and resolution of issues
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…

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

"I found multiple features in AlertSite that I like. One is data monitoring history, for example, a history of the blackouts and the data. Sometimes, there's a glitch in the application that AlertSite can capture, and the tool notifies you about that glitch. It also identifies issues that could happen in the future. AlertSite is also a fast tool that you can use to monitor on-premise servers, internal applications, and even global applications. The data is available on a single UI in AlertSite, so there's no need to monitor and click on different applications or URLs. I also love that the tool is quite user-friendly, apart from being fast."
"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."
"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."
"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"There are custom reports available along with the inbuilt reports."
"The alerting capabilities were really helpful."
"The alerting capabilities of AlertSite were really helpful."
"The solution's basic visibility is one of its most valuable features. So, it is a solution that is easy to use...The solution's initial setup process was straightforward."
"The feature I appreciate the most about Splunk Observability Cloud is Synthetic Monitoring."
"Splunk Infrastructure Monitoring reduces our mean time to resolve. We are more proactive than reactive."
"I have definitely seen a return on investment with Splunk Observability Cloud, particularly through how fast it has grown and how comfortable other teams are in relying on its outputs for monitoring and observability."
"We haven't really experienced any glitches or bugs."
"The solution's most valuable aspect is its ability to get information about all of the security measurements in my environment."
"Splunk Observability Cloud has helped improve my operational performance; previously, we used Elastic for similar purposes, and this has allowed us much more visibility into what we're working on with usable dashboards and metrics, which has been awesome."
"We utilize the APM and auto-detectors, as the core metrics and core alerts are available for us, which are the features of Splunk Observability Cloud that I appreciate the most."
 

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. Therefore, the false alert needs to be fixed."
"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."
"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."
"It is not compatible with all of the product platforms that we use."
"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"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."
"The pricing would be one area for improvement."
"If a customer utilizes third-party tools and wants to forward data from Splunk Observability Cloud, seamless integration would be beneficial."
"Once you see the issues related to the scalability part, you need to understand that it is a warning triangle. After seeing the warning triangle, you need to realize that you cannot trust any of the numbers you see in the chart because it is not a complete, full data set."
"The UI of Splunk Observability Cloud is one of the major issues; it's old and has been there for more than 10 years, acquired by other applications from other companies. It's time to reinvent how the UI is going to work with the AI modules and integrations, making it softer and cleaner."
"Splunk Observability Cloud could be improved in terms of integrations with more technical add-ons, such as Zoom."
"There is not a lot of support for the tool's on-premises version, especially since everything is on the cloud."
"I would like to see an improvement and some innovation in the customer interface."
"There's no standard use case available where you can see the utilization of the number of use cases I have."
