Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

Unified observability has improved real-time governance and now drives data-led decisions
Log Observer Connect is embedded here, but we are facing some delays in centralized log collection and analysis, which can be further fastened. We are collecting all the data metrics and decision-making insights, but all these data-driven decisions coming from different applications are not connected somewhere. A consolidated form or correlation of these insights is not happening between each other due to which we feel we are missing something significant. Some generalized feedback includes that predictive alerts or alarms which can be integrated with AI-driven alarms and alerting features should be established so that there is AI-driven intelligence and anomaly detection happening with a complete systematic process in service delivery. Application dependencies are huge, and business and operational dashboards should be improved. Right now there are very interactive custom dashboards, and every now and then, the personalization of enhancements keeps happening. KPI monitoring, executive reporting, and analytics have definitely been introduced to a great extent. There are few things in cloud-native monitoring, such as integration with AWS and Azure, where we sometimes do face lags. Those things can definitely be improved upon. I have used Datadog and Dynatrace before using Splunk Observability Cloud. Datadog was definitely recommended by most of our peers because of its very strong comprehensive observability and very strong and unique dashboard systems. Dynatrace was also very good because they have offered a lot of AI-driven analysis methods and processes, which was helping our organization a lot. Since our organization has a very strong IT ecosystem for agriculture, very different kinds of customized things are required.

Quotes from Members

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

Pros

"The solution has helped to increase application and network uptime, reduced our mean time to repair significantly for application and network issues, and cut our overall troubleshooting time from an hour down to five minutes."
"We have seen a lot of return on investment: We have been able to recover radios in the field, we know exactly what is going on, we cut down fines from the service commission, and we have seen a measurable decrease in mean time to know, cutting troubleshooting down by days as we can now see the issues."
"The most valuable features are speed and cost."
"It is very rock solid, and we hardly have any hardware issues."
"Go with NETSCOUT."
"It's an easy product to set up."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"The integration of business context in the telemetry has helped to reduce MTTR by fifty percent, which has been the key metric."
"My experience with this solution in analyzing machine data is really good."
"It is a good tool. It allows you to set alerts for application and infrastructure monitoring, and it allows you to create dashboards."
"Splunk Observability Cloud has indeed helped me improve the operational performance and resilience of my company."
"Splunk Observability Cloud is highly effective in improving digital resilience, as real-time visibility, proactive alerting, fast root cause analysis, distributed tracing, and AI-driven insights enable anomaly detection, which allows us to quickly understand failures, recover faster, maintain system availability, and handle failures in complex distributed environments by seeing how services interact and where breakdowns occur."
"I like the fact that Splunk APM makes it easy to connect to the application database and run queries against the data."
"Once configured correctly, the analysis reporting the Splunk APM provides is better than that of the other APM tools."
"It's beneficial for monitoring performance and infrastructure, especially when deploying applications with multiple versions with Git."
 

Cons

"There is a timeout feature that we have been asking for awhile."
"The single pane of glass feed still needs work."
"We don't use the single pane of glass view, even though we own it."
"It can be scalable. It just costs too much."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM."
"Sometimes, we can't access it."
"Being able to manage the packet flow switches in nGeniusONE would be great."
"The NetFlow Collectors could handle more flows per minute."
"To improve Splunk Observability Cloud, we need more applications to be included in the observability so that more applications can have agents to monitor them and bring that information to the cloud."
"When we have too many detectors in place for one particular app, such as when I have created 50+ detectors through my account, the entire page becomes a bit loaded when creating the 51st detector, feeling heavy and taking time to load."
"The price of this solution is very high and can be improved."
"There is room for improvement in customer support due to delays and standard feedback responses."
"The RUM part of Splunk Observability Cloud can be improved significantly."
"Splunk Observability Cloud could be improved in terms of integrations with more technical add-ons, such as Zoom."
"The initial setup of Splunk Real User Monitoring (RUM) was easy. The solution is deployed on-premises."
"Splunk's functionality could be improved by adding database connectors for other platforms like AWS and Azure."
 

Pricing and Cost Advice

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"This product could be cheaper."
"The price is a little high."
"I would like it to be more scalable with less spend."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"Splunk Observability Cloud is expensive."
"This is an expensive solution."
"I would rate the price of Splunk Infrastructure Monitoring as an eight out of ten, with ten being the most expensive."
"Licensing cost is the biggest argument I get from those divesting from Splunk. There are those within our organization who say we are going to go to other tools since Splunk is too expensive."
"Splunk APM is expensive."
"The pricing is based on several factors, including the scale of deployment."
"It appears to be expensive compared to competitors."
"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."
