Which log type records statistics, metrics, and debugging information on a Citrix ADC in a proprietary binary format?

• A. Syslog
• B. Nslog
• C. Nsconfig
• D. Nstrace

Answer: (B)

Nslog is the binary log format used by Citrix ADC to store internal telemetry, including statistics, metrics, and debugging information. This binary log is designed for efficient capture of high-volume data and detailed troubleshooting, and it isn’t intended to be read directly in a text editor. You typically handle nslog data with Citrix diagnostic tools or by converting it for analysis.

Syslog is a standard text-based logging path for general event messages sent to centralized servers. Nsconfig pertains to the appliance’s configuration data, not runtime logging. Nstrace is focused on tracing protocol-level traffic for in-depth debugging, rather than collecting broad statistics and metrics.
