KL
Network Engineer at Inniti Network Solution
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."
"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"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."
"Splunk Observability Cloud has proven to be beneficial for our organization, helping improve operational performance and company resilience while reducing the costs of unplanned digital downtime."
"Dashboards help the application support teams to have a quick look at how their systems are running. It helps other teams as well."
"What I appreciate most about Splunk Observability Cloud is the correlation feature, specifically the ease of correlating logs and issues to those traces to see where within the path of the business function is failing."
"Splunk has drawn our attention to how the network is running. If there are alarms on things that are not functioning, it gives us early warning on problems that could arise."
"With the metrics collection, I can proactively find incidents and work on the major issues when they happen and predict these issues."
"The initial setup was straightforward."
"The dashboards in Splunk Observability Cloud are amazing, and if you configure them correctly, they are amazing, and it is quite fast as well."
"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."
 

Cons

"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 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."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"It does not have a user-friendly interface and it is difficult to use."
"Splunk Observability Cloud experienced a significant outage recently when it went down for approximately five to six hours."
"Splunk APM's performance could be improved - at the moment, it's very slow and takes forever to give me what I want."
"The solution's machine learning deployment is hard and should be made user-friendly."
"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."
"If it is a new deployment and you have a medium client with about 2,000 users or computers or servers, it will take about six months just to install and configure."
"They need more EDR functionalities."
"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 a very cost-efficient solution."
"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
"The solution's pricing is costly."
"It appears to be expensive compared to competitors."
"Licensing cost is the biggest argument I get from those divesting from Splunk. There are those within our organization who say we are going to go to other tools since Splunk is too expensive."
"Splunk Observability Cloud is expensive."
"The pricing is reasonable."
"Splunk has been fairly expensive, but it has been predictable."
