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.

Collaborates performance metrics with log data to pinpoint the exact cause of issues and offers error detection
Splunk APM is a robust tool with many capabilities. There are always areas for potential improvement to enhance its functionality and user experience. For Splunk APM, there could be simplified navigation, like streamlining the user interface to make navigation more intuitive for our users, especially those new to APM, which can enhance usability. We can provide more customization options for dashboards and visualizations to help users tailor the platform to their specific needs. There could be more integration capabilities with a wider range of third-party tools and platforms would also be beneficial. By focusing on these areas, Splunk APM can enhance its value proposition, improve user satisfaction, and better meet the evolving needs of organizations monitoring their application performance.

Pros

"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."

"I like the fact that Splunk APM makes it easy to connect to the application database and run queries against the data."
"It's beneficial for monitoring performance and infrastructure, especially when deploying applications with multiple versions with Git."
"The best features in Splunk Observability Cloud are the metrics; I can see any logs or anything related to the server or services we want to monitor, and the metrics are a good function."
"The alerts are the most valuable feature."
"Great monitoring of network devices."
"The Add data feature lets you gather any type of log and easily analyze it."

Cons

"I would like to see improvements made to the user guide."
"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."
"It would be useful if they provided some help pages. If you don't know too much about the tool, there should be more documentation readily available. It would be useful if they had a help button embedded in the solution so you could ask questions and get answers."
"The initial setup of Splunk Real User Monitoring (RUM) was easy. The solution is deployed on-premises."
"This solution is difficult to configure and the instructions are complex."
"Splunk APM's performance could be improved - at the moment, it's very slow and takes forever to give me what I want."
"The end-to-end visibility is lacking because Splunk cannot directly monitor network devices."
"We currently lack log analysis capabilities in Splunk APM."

"The product is a bit expensive considering the competition but the company may negotiate the price."

"Splunk APM is expensive."
"Splunk Observability Cloud is expensive."
