A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

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 generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"One of the valuable features is the packet decoding."
"Sometimes it took a month to troubleshoot something that we can now do within days."
"With the metrics collection, I can proactively find incidents and work on the major issues when they happen and predict these issues."
"The most valuable features are troubleshooting and optimizing application performance."
"Splunk Observability Cloud has helped me reduce my mean time to detect, and we have worked on around 80 applications last year for one particular client, and since the MTTR has improved drastically, they have given us 245 applications, which is around 150 applications added to the previous number of applications, which is definitely a performance improvement."
"Splunk Observability Cloud has indeed helped me improve the operational performance and resilience of my company."
"The tool is efficient in collecting, monitoring and evaluating logs."
"Splunk APM helps us to find errors immediately and resolve them."
"The vibrant dashboards are valuable."
"Splunk Infrastructure Monitoring reduces our mean time to resolve. We are more proactive than reactive."
 

Cons

"Room for improvement exists in filtering in the packet decode."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"I would like to see improvements made to the user guide."
"I would say that this is not a scalable solution."
"If it is a new deployment and you have a medium client with about 2,000 users or computers or servers, it will take about six months just to install and configure."
"There is not a lot of support for the tool's on-premises version, especially since everything is on the cloud."
"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."
"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."
"In terms of pricing, I have one issue with Splunk Observability Cloud; in a large-scale organization, it does not have features such as cost optimization or budgeting for observability spend."
"A lot of customers had a hard time effectively searching within the data in Splunk. There is a learning curve from searches to indexes and using all the macros that we have created. It is a little difficult for somebody who has not used it quite a bit and does not have a lot of practice with it, but the AI features that we have been hearing about through Splunk will make it a lot easier for us to use human language to search this data. That is big. That is pretty powerful, and that will help a lot with our customers."
"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."
"If a customer utilizes third-party tools and wants to forward data from Splunk Observability Cloud, seamless integration would be beneficial."
 

Pricing and Cost Advice

"Licensing is quite expensive."

"Splunk Observability Cloud is expensive."
"Splunk Infrastructure Monitoring is an expensive solution."
"The price of Splunk APM is less than some of its competitors."
"Splunk APM is expensive."
"I would rate the price of Splunk Infrastructure Monitoring as an eight out of ten, with ten being the most expensive."
"The solution's pricing is costly."
