KL
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.

Alerting improves incident response across teams and enables faster awareness before customer impact
Splunk Observability Cloud could be improved in terms of integrations with more technical add-ons, such as Zoom. Although they have one with Zoom, it's not available in the cloud, so having that feature would be beneficial. Essentially, Splunk should continue expanding to create easier ways to ingest logs from different products. 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. While IT leaders may not drill down, it's crucial to create levels of dashboards for technical users to find root causes, making it effective for stakeholders.

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."
"Once configured correctly, the analysis reporting the Splunk APM provides is better than that of the other APM tools."
"The company has many systems that the customer is paying to access. Splunk APM issued via AppDynamics helps find problems in the feed. It reduces the risk of supervising all the devices. I can supervise the flow and simulate the conditions of the repository across several dashboards to show what's happening at the moment."
"It is very easy to monitor multiple cloud environments. It's like a single pane of glass for us. We can use it to monitor our on-prem and both of our cloud environments as opposed to having different tools for each environment. It makes it all come together in one tool."
"Splunk Infrastructure Monitoring gives us complete visibility without the need for storage."
"The alerts are the most valuable feature."
"Detectors are a powerful feature."
"The feature I appreciate the most about Splunk Observability Cloud is Synthetic Monitoring."
"Splunk Real User Monitoring (RUM) has one great advantage in that if they have SAP users, they can monitor their SAP applications."
 

Cons

"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"There is a lot of room for improvement with the automation."
"Support from Splunk is not very helpful because Splunk doesn't have a dedicated APM; they only have one APM engineer in Korea."
"Splunk Observability Cloud has not yet completely improved our operational performance for our company's resilience as we are just starting out, however, it will help us ultimately to reduce incident time."
"The pricing would be one area for improvement."
"I've been using the Splunk query language, and it can be a bit time-consuming to set up the queries I need."
"The licensing model is expensive. We need to monitor the amount of data ingested because the cost is based on the data collected."
"Regarding dashboard customization, while Splunk has many dashboard building options, customers sometimes need to create specific dashboards, particularly for applicative metrics such as Java and process terms. These categories of dashboards would be very helpful for customers."
"They do not have all the features that I expect right now."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"This is an expensive solution."
"The solution's pricing is competitive. I rate the solution's pricing a seven out of ten. The price of the solution could be cheaper."
"Splunk Observability Cloud is expensive."
"Splunk Infrastructure Monitoring is an expensive solution."
"Splunk APM is a very cost-efficient solution."
"The price of Splunk APM is less than some of its competitors."
"The pricing is reasonable."
"Splunk has been fairly expensive, but it has been predictable."
