It's not uncommon to hear people mention "logging" or "logs" in relation to CiviCRM. There are some different usages of "log":
- There's CiviCRM's debug log files in sites/default/files/civicrm/CiviCRM.HASHHASH.log (what)
- There's the DB table log
civicrm_system_log
(has an API, only used for IPN data, seeCRM_Utils_SystemLogger
and forum post). - There's Data Logging configured at
civicrm/admin/setting/misc
(mysql logging via triggers). AKA Change Log or Trigger Logging or Detailed Logging. - There's "userFrameworkLogging", which means "dump errors to the CMS logging" (may be Drupal specific)
- There's the Activity Log, which is the view of activities over time.
yikes.
