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

"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."
"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"I have primarily used it to go back into the past and understand why something happened. It provides enough information to do research and figure things out."
"We haven't really experienced any glitches or bugs."
"Splunk Infrastructure Monitoring reduces our mean time to resolve. We are more proactive than reactive."
"Once configured correctly, the analysis reporting the Splunk APM provides is better than that of the other APM tools."
"Splunk Observability Cloud has helped to improve my operational performance because it is useful for my company, helping to solve issues, reduce the manpower, and reduce the man-time to solve it."
"Splunk's dashboards are great."
"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 most valuable features include user time tracking and the ability to analyze application load times."
 

Cons

"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"Room for improvement exists in filtering in the packet decode."
"I would say that this is not a scalable solution."
"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."
"The main improvement I would suggest for Splunk Observability Cloud would be offering the ability to implement custom apps, specifically allowing Python scripts that Splunk Cloud could host."
"In Splunk Observability Cloud, I notice room for improvement in synthetic monitoring. It does not provide output based on server names."
"In terms of additional features I would want to see in future releases, since Cisco acquired Splunk, more Cisco integration could be beneficial."
"There is room for improvement in customer support due to delays and standard feedback responses."
"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."
"There is not a lot of support for the tool's on-premises version, especially since everything is on the cloud."
"I need a tool that can deal with all the security solutions that will find security monitoring compliance requirements, so I'll stick to BigFix over Splunk because I'm not that big a fan of Splunk, to be honest."
"It's a bit difficult to use. It takes some time to get into it and to get it to do what you would like it to do. It is not straightforward to use it."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"It is expensive."
"The solution's pricing is costly."
"The pricing is reasonable."
"It appears to be expensive compared to competitors."
"The price of Splunk APM is less than some of its competitors."
"Splunk APM is expensive."
"This is an expensive solution."
"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."
