I encountered several issues while trying to create solutions for this advanced version, which seem unrelated to query or data issues.

Valuable Features

Splunk User Behavior Analytics offers advanced threat detection, scalability, and integration for robust security and data analysis solutions.

Featured Reviews

Ahmed Naguib - PeerSpot reviewer
Director at Techpace
Dashboard design excels while prediction algorithms need improvement
Splunk User Behavior Analytics is still an immature product, so it still needs some R&D to be able to be mature in the market. The prediction, algorithms, and ML codes behind Splunk User Behavior Analytics need to be more tuned. The logic needs to be reviewed because it has many false positives. For Splunk User Behavior Analytics, it is not yet a mature product and we are not recommending this to mature customers for now. The machine learning algorithm in Splunk User Behavior Analytics is actually the core thing that needs to be updated because this feeds all the other functions inside it. If the ML functions are not good enough, that means the risk scoring and all other related information will not be correct.

High-speed shared storage has accelerated AI research workflows and supports massive job queues
The best features Weka offers are high speed, exceptional performance, and reliability. It is probably the best file system I have ever used. These features have helped my workflows and users by enabling us to train and perform inferencing of AI workflows of proteins against target diseases, which allows us to run jobs in approximately half the time that we would with slower storage. Weka is always available, incredibly reliable, and backed up, so we could not do this work without it. Additionally, Weka is incredibly easy to use because there is a web UI that allows us to create and resize file systems at will, making different directory structures available to different users at any given time, and the speed is exceptional. Weka has positively impacted my organization because we previously had NFS, which would take down the cluster when under high load. Now we have no concerns about highly loaded multiple thousands of jobs running simultaneously against this file system. The system handles it without any issues. To share more about the scale, we have anywhere between 1,000 to 10,000 jobs in the queue at any given time, and the system handles it without any problems. Our volumes are approximately half a petabyte on one system and about a third of a petabyte on another system for various storage uses, and it enables all our work to go efficiently.
