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

"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."

"Go with NETSCOUT."

"The packet flow switch is the most valuable aspect of the solution."

"The product is stable. I have never had any issue where we have lost an InfiniStream, or visibility from that particular InfiniStream, throughout the bank."

"It helps us to assist our customers to isolate problems. If it is us who is having the problem, then we can use it to streamline the process."

"We use it for monitoring whenever we update a new circuit or site."

"This solution has cut our overall troubleshooting time, sometimes going down to a few hours over what might have taken one to two days to fully troubleshoot an issue, and it has helped to increase our application uptime as we try to keep the five nines."

"We have seen a lot of return on investment: We have been able to recover radios in the field, we know exactly what is going on, we cut down fines from the service commission, and we have seen a measurable decrease in mean time to know, cutting troubleshooting down by days as we can now see the issues."

More NETSCOUT InfiniStreamNG pros

"The initial setup was straightforward. We didn't find it to be too complex."

"The ability to create custom dashboards is one of the best features and that's typically why most people deploy Splunk."

"I manage six tools, but Splunk Observability Cloud is one of my favorites, and I aspire to build my career specializing in it because it has great features, more attention in the market, and is a relatively new tool with promising growth."

"The most valuable feature in this solution is the log searching."

"The solution's most valuable aspect is its ability to get information about all of the security measurements in my environment."

"The solution overall is very valuable for me."

"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 Infrastructure Monitoring gives us complete visibility without the need for storage."

More Splunk Observability Cloud pros

Cons

"There is a timeout feature that we have been asking for awhile."

"Sometimes, we can't access it."

"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."

"The single pane of glass feed still needs work."

"The NetFlow Collectors could handle more flows per minute."

"Being able to manage the packet flow switches in nGeniusONE would be great."

More NETSCOUT InfiniStreamNG cons

"We were facing some challenges with the stability of Splunk Observability Cloud regarding the login page. It was not working several times and was not accepting SSO authentication."

"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."

"There's a lot of talk about AI-powered analytics and guidance in Splunk Observability Cloud. I didn't get a great sense of how much of it is actually working; there are a lot of AI hallucinations."

"Splunk APM's performance could be improved - at the moment, it's very slow and takes forever to give me what I want."

"In the next release, I would like to see more integration with other solutions."

"The learning curve for understanding all features should be improved, and the cost can increase."

"The deployment can be quite complex."

"To improve Splunk Observability Cloud, I wish they could develop more in the area of pricing and cost transparency, provide a smoother learning curve, and enhance the log management experience, ensuring that log navigation is not solely focused on metrics and tracing but also has good search performance to understand larger data sets."

More Splunk Observability Cloud cons

Pricing and Cost Advice

"I would like it to be more scalable with less spend."

"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 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."

"This product could be cheaper."

"The price is a little high."

"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."

"The pricing is reasonable."

"The price of Splunk APM is less than some of its competitors."

"Splunk APM is a very cost-efficient solution."

"The pricing is based on several factors, including the scale of deployment."

"Splunk APM is expensive."

"It appears to be expensive compared to competitors."

"I would rate the price of Splunk Infrastructure Monitoring as an eight out of ten, with ten being the most expensive."

"Splunk Observability Cloud is expensive."
