EM Log RecordsΒΆ
The REDCap EM logging feature provides an elegant way to maintain specification backups. In order to track specification backups across EM log entries, each export specification is identified by the EM parameter export_uuid. This value is an RFC-compliant universally unique identifier, generated by the Javascript function YES3.uuidv4 function in js/yes3.js.
The YES3 Exporter II makes extensive use of External Module logs, both for logging actions such as downloads and filesystem exports and for storing the export specifications and event prefixes. An EM log parameter named log_entry_typeindicates the function of the log record. Below is a listing of each log_entry_type value and the purpose of the associated EM log record.
| log_entry_type | EM Log record purpose | includes export_uuid |
|---|---|---|
| yes3-export-specification | an export specification | yes |
| yes3-export-events | event prefixes | no |
| yes3-export-log | an event associated with an export or a download | yes |
| yes3-export-cron-log | a daily cron summary across all projects and exports | no |
