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.

Quotes from Members

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

Pros

"One of the valuable features is the packet decoding."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"Splunk APM has helped us to standardize logging and monitoring procedures."
"The solution monitors attacks or unauthorized access to the information we want to protect."
"Detectors are a powerful feature."
"It supports proactive management, enhances security, and improves operational efficiency."
"It is a good tool. It allows you to set alerts for application and infrastructure monitoring, and it allows you to create dashboards."
"The most valuable thing that we have seen within our group is the ability to ingest all this raw data and have it organized in a certain way so that different groups can get effective alerting from this massive amount of raw data that is out there."
"The data collection from our VMs, containers, databases, and backend components is valuable."
"The Add data feature lets you gather any type of log and easily analyze it."
 

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."
"I would like to see improvements made to the user guide."
"The initial setup of Splunk Real User Monitoring (RUM) was easy. The solution is deployed on-premises."
"Splunk APM should include a better correlation between resources and infrastructure monitoring."
"This solution is difficult to configure and the instructions are complex."
"The UI enhancements could be a way to improve the solution in the future."
"There is room for improvement in customer support due to delays and standard feedback responses."
"The solution should have more sensors regarding fiber intelligence for security measures."
"There are always areas for potential improvement to enhance its functionality and user experience."
"One thing I recently ran into was that the logs on the server most often get Gzipped after they have been rotated. We found that we were not monitoring some of the things, so we had to go back and pull them in. Right now, it pulls one at a time, untars it, or unzips it, so I cannot look at the entire history. There can be an improvement in that area."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"Splunk APM is expensive."
"Splunk can be expensive, as its licensing is based on the daily data ingestion volume."
"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
"Splunk Observability Cloud is expensive."
"The solution's pricing is costly."
"It is expensive."
"The price of Splunk APM is less than some of its competitors."
"It appears to be expensive compared to competitors."
