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."
"Sometimes it took a month to troubleshoot something that we can now do within days."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"One of the valuable features is the packet decoding."
"It's starting to help reduce our Mean Time to Detect (MTDD) because the visibility we gain is unprecedented, allowing us insight into applications that we've never had before."
"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."
"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 product's deployment phase is good and very easy because it is done with OpenTelemetry for most of the parts."
"This solution is very quick to deploy as it is a SaaS solution and integrates with tools like ServiceNow."
"The solution's service map feature allows us to have a holistic overview and to see quickly where the issues are."
"The most valuable feature is dashboard creation."
"The solution has significantly helped improve my operational performance and my company's resilience by providing real-time insights."
 

Cons

"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"I would like to see improvements made to the user guide."
"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 say that this is not a scalable solution."
"Room for improvement exists in filtering in the packet decode."
"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 cardinality is pretty low."
"Splunk Observability Cloud experienced a significant outage recently when it went down for approximately five to six hours."
"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."
"The solution's machine learning deployment is hard and should be made user-friendly."
"They need more EDR functionalities."
"Splunk's functionality could be improved by adding database connectors for other platforms like AWS and Azure."
"Regarding the negative side, I think the licensing can be much better because it is based upon host units and there is additional licensing for the number of traces that I can bring in."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
"Splunk APM is a very cost-efficient solution."
"It appears to be expensive compared to competitors."
"The solution's pricing is costly."
"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."
"I would rate the price of Splunk Infrastructure Monitoring as an eight out of ten, with ten being the most expensive."
"This is an expensive solution."
"It is expensive."
