Identifies and analyzes performance issues quickly using in-built AI and ML

With Alluvio AppResponse, there is an in-built analytical analysis with AI and ML, which identifies and provides data such as the number of TCP retransmits, web access time, total connection time out, total connections established, and server-side errors. The RTCC response time composition chart is crucial because it helps pinpoint the issue's origin, whether from the server, network, or application side. It's a superb product when compared to SolarWinds SAM, which is agent-based, while Alluvio AppResponse captures all traffic from the core switch.

Service health has been monitored and visual insights support proactive telecom operations

The installation process is the first aspect I dislike about Splunk ITSI (IT Service Intelligence). If you do not configure it correctly, you will encounter issues in the search head. Because we use a distributed environment where each component has its own specific roles, installation is critical and requires careful attention. Splunk ITSI (IT Service Intelligence) is built with many applications. It is a compressed file, and when you extract the Splunk ITSI (IT Service Intelligence) app, you receive approximately 19 apps. Some applications, add-ons, and packages must be installed on specific components. If you do not configure an application correctly, it will not work. Sometimes we encounter issues during installation because of this complexity. I believe the installation process should be more uniform, meaning it could be deployed across all components to avoid post-installation issues. Sometimes after installation, you receive errors, and users cannot access Splunk ITSI (IT Service Intelligence). We have experienced this type of issue due to installation errors. I believe there is currently room for improvement regarding scalability. When we create Glass Tables containing many searches, the Glass Tables sometimes fail due to memory constraints, and we receive error pages. Splunk ITSI (IT Service Intelligence) should have a lightweight version to address these concerns. I would rate current scalability as medium.

Quotes from Members

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

Pros

"You need a packet capture device to perform any type of network monitoring. It helps ensure that network overloads don't happen with alerts allowing for proactive decisions."

"AppResponse is a total solution that gives you end-to-end visibility into applications at all levels, from Layer 1 to Layer 7. We can trace all those sections: physical, IP, transport, presentation, application, etc. It gives us the full picture."

"Ability to see end to end user, application, server, and network response time and throughput data."

"I have found the AppResponse, which is a packet capture solution, very good. It gives you the ability to drill down back in time. You've got all the packets there. You can troubleshoot it later, not immediately. It's very interesting."

"It's a stable product. Riverbed has invested a significant amount of research and development into it, so it's a solid tool overall."

"The most valuable feature of Alluvio AppResponse is the actual response time for measuring performance."

"We really like the scalability capabilities."

"It provides us with complete visibility of every packet."

More Alluvio AppResponse pros

"We liked the built-in calculation of health scores."

"The most valuable features are the agility, being able to ingest many data sources with no limitation on capacity."

"The most valuable aspect lies in its utilization of predictive analytics to anticipate and prevent incidents within a window of twenty to thirty minutes."

"The glass tables are very helpful."

"I like ITSI's glass tables. They're easy to navigate by clicking through them. The interface isn't that much different from other products I've used. It provides all the information we need in one place."

"Having worked closely with Splunk support engineers, I've observed their high capabilities in resolving issues."

"Splunk Episodes are valuable because it correlates and aggregates all the information, and you do not have one million events to look at and triage, so it is quite convenient."

"It's scalable and expands well."

More Splunk ITSI (IT Service Intelligence) pros

Cons

"They need to better integrate with products and solutions from different vendors."

"Need to bring back the NetFlow module for AppResponse."

"The recent changes in corporate structure may have caused some decrease in support quality."

"The reporting models need improvement as most of the time, we have to customize the reports manually."

"Integration between NPM and APM solutions would improve efficiency. There is no agent on the server site related to AppResponse."

"If Alluvio AppResponse reduces its cost, it will be more beneficial for customers to monitor their application and network performance."

"The recent changes in corporate structure may have caused some decrease in support quality."

"The pricing is on the higher side of things. If they could lower it, that would be ideal."

More Alluvio AppResponse cons

"ITSI is an almost perfect tool, but there is room for improvement in a few features like the deep dive and multi-KPI alerts. We're using most of the features like service API, coding searches, and aggregation, but our team members hardly use multi-KPI and deep dive. We don't use the multi-KPI or deep dive because everything is available in the service KPI. I don't think this feature is necessary."

"We're getting alerts with delays of maybe five minutes, however, we'd like to see real-time alerting in the future."

"The installation process is the first aspect I dislike about Splunk ITSI (IT Service Intelligence). If you do not configure it correctly, you will encounter issues in the search head."

"The end-to-end visibility in Splunk ITSI is limited and has room for improvement."

"We have problems doing upgrades and operating alternate new versions."

"It would be advantageous to enhance the dashboard by incorporating sections for monitoring, service health, and a filter for the KPIs."

"Quality-of-life features have room for improvement."

"Splunk ITSI should include ease of integration and more templating."

More Splunk ITSI (IT Service Intelligence) cons

Pricing and Cost Advice

"The price is a little bit high, especially because we have to pay an import tax."

"The licensing model is expensive compared to its competitors, but the service it gives to your business, and the data quality, means that it's worth it."

"It is costly for small and medium businesses."

"The solution is no more expensive than other products."

"Splunk ITSI is expensive."

"Splunk pricing is high."

"Splunk ITSI is expensive compared to other tools."

"I know that it is expensive, but I do not think there is another solution that can do similar things for that price."

"The pricing of Splunk is a bit high."
