Which NetScaler log file is used for real-time troubleshooting?

• A. events.log
• B. ns.log
• C. system.log
• D. trace.log

Answer: (B)

Real-time troubleshooting on NetScaler hinges on watching the live operational log as events happen. The ns.log file is the primary source for this, recording runtime messages from the NetScaler processes in real time, so you can monitor symptoms as they occur and correlate them with actions or failures. You can view it live with commands like tail -f /var/nslog/ns.log to see new entries as they’re generated.

Other logs have different roles: events.log captures event messages such as state changes, system.log holds general system messages, and trace.log provides detailed, verbose debugging traces intended for deep investigations. For quick, ongoing troubleshooting, the live operational data in ns.log makes it the best fit.
