# CSV file format

[Table: Performance monitoring CSV output file format](/sec/docs/oas-aref-csv-file-format-3-28#Tab_PerformanceMonitoringCsvOutputFileFormat) lists the fields used in a CSV file used for performance monitoring.

For more information about using the CSV plugin for performance monitoring, see the OneSpan Authentication Server Administrator Guide, Section "Performance monitoring – Plugins".
