Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

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

"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"When we have mobile operators who are signal partners, where one is the roaming host and another is the roamer, we are able to see their traffic. Their packets are able to detect if any faults to develop, and at what point they fail."
"It helps us get to root cause quickly. With utilization and consumption of bandwidth, we can usually see what application is taking as much as they should (or shouldn't), then account for it accordingly."
"The most valuable features are speed and cost."
"We use it for monitoring whenever we update a new circuit or site."
"The product retains a lot of log data for subsequent analysis."
"It can monitor, get the data, and then report on the data."
"The most valuable features include user time tracking and the ability to analyze application load times."
"Splunk Infrastructure Monitoring provided our customers with visibility into their overall infrastructure."
"The best feature of this product is the latency and processing of all the telemetry that is being received, which gives full visibility at the right time."
"Splunk Real User Monitoring (RUM) has one great advantage in that if they have SAP users, they can monitor their SAP applications."
"It is a good tool. It allows you to set alerts for application and infrastructure monitoring, and it allows you to create dashboards."
"The maintenance of Splunk Observability Cloud is very easy; it's manageable."
 

Cons

"The NetFlow Collectors could handle more flows per minute."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"We don't use the single pane of glass view, even though we own it."
"I'd like them to make the product more user-friendly."
"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"I would like to see an improved level of stitching between IPs."
"There is a timeout feature that we have been asking for awhile."
"Splunk's functionality could be improved by adding database connectors for other platforms like AWS and Azure."
"I would rate Splunk technical support at six out of ten. When we have a problem and need to create a case, the response isn't quick."
"Particularly what we're having is disconnection from the cloud console, where we will be working in it and receive a message saying that we've been disconnected and have to wait for it to come up."
"They do not have all the features that I expect right now."
"In the next release, I would like to see more integration with other solutions."
"I would like to see an improvement and some innovation in the customer interface."
"Splunk Observability Cloud could be improved with better integration with AppDynamics, as we know that's coming, however, it is an issue we've had between the OpenTelemetry and the AppDynamics collector."
"The UI enhancements could be a way to improve the solution in the future."
 

Pricing and Cost Advice

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"This product could be cheaper."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"The price is a little high."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"I would like it to be more scalable with less spend."
"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
"Splunk Infrastructure Monitoring is an expensive solution."
"The pricing is reasonable."
"This is an expensive solution."
"It is expensive."
"Splunk APM is expensive."
"Splunk APM is a very cost-efficient solution."
"It appears to be expensive compared to competitors."
