R/W(+): Dynamic Read / static and dynamic Write

For online temporary change or permanent change, use the admin+ utility to modify the parameter value for a specific instance. A restart is needed for permanent changes.

This parameter defines the level of details recorded in the log files.

Main values available (*):

• INFORM
• DEBUG (**)

(*) Other values are possible (TRACE, WARN, SECURITY, FAILURE, FATAL).

(**) Caution: Once set to DEBUG log level (without specified domain), the system produces a high stream of several MB per minute (about 20MB).

Special value: DEBUG

• The DEBUG level is reserved to code inspection and bug hunting. In addition, this specific level can be combined to a domain name to focus on a specific feature and to limit the quantity of generated logs. The available domains are:
  • ALL : all domains
  • NET : BARBUS network protocol
  • SQL : SQL requests
  • HB : HA heartbeat protocol
  • AK : HA auto-kill mechanism
  • TEST : assertion testing
  • CACHE : cache behavior
  • LOCK : resources locking mechanism
  • RERATING : rerating mechanism
  • JOB : jobs
  • NOTIF, NOTIF_STOR, NOTIF_PUBL : notifications
  • ACCOUNT : business operations on subscriber accounts
  • HTTP : HTTP connections
  • TAX : tax framework
  • CLIENT_EVENT : client related events
  • OPERATION : stateful rate operations
• Examples:
  • DEBUG+SQL prints all debug traces concerning the SQL requests sent to the database.
  • DEBUG+NET+CACHE displays the debug traces concerning the network and the cache management.
  • DEBUG+ALL-NET displays all debug traces except the traces concerning the network.
  • DEBUG without any domain name display all debug traces which cannot be attached to a specific domain.
