Performance monitoring impacts operations with fast storage setup
Having eyes on performance for storage through the Analyzer is valuable for me. The Ops center from Hitachi lets us see all storage in one place, unlike Dell and EMC, where we work on one storage. The Analyzer and the Ops center provide a better solution. Before this, we used a CVP with slow performance. This solution works better than before. The visualization vector in the last version is something we have. It is easy to work with and add the storage type. There is no difficulty in adding it.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Cons

"The dashboard needs improvement."

"Writing queries is a bit complicated sometimes."
"It can be tough to determine if you are getting all of the value out of your investment at times."
"I would like to get visibility into the data pipelines on heavy forwarders and indexers to see exactly their source and the cause of saturation when it occurs. This would help us learn even more about our high use applications."
"The main improvement needed in Splunk Enterprise Security is its system visibility after installation."
"The algorithms customization of Splunk could improve. They have limited algorithms for machine learning support. If they can allow the user to add more machine learning algorithms, such as the ability to choose the algorithm that a user might want. Additionally, they should provide the required libraries for those algorithms, and then analyzes the data for use."
