Senior Manager at a financial services firm with 10,001+ employees
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.

Dashboard personalization enhances troubleshooting capabilities
A valuable feature of VMware Aria Operations for Logs is its ability to allow personalization of dashboards and requests. This personalization capability is crucial because it helps tailor the tool to specific needs. It also has many effective features for log analysis, making it a competent tool despite not having a comprehensive comparison with other tools.
