Which events are logged for a particular daemon are determined by the value of configuration variable <SUBSYS>_DEBUG. The possible values for <SUBSYS>_DEBUG categorize events, such that it is possible to control the level and quantity of events written to the daemon's log.
Configuration variables that affect daemon logs are
Daemon logs are often investigated to accomplish administrative debugging. condor_config_val can be used to determine the location and file name of the daemon log. For example, to display the location of the log for the condor_collector daemon, use
condor_config_val COLLECTOR_LOG
Within the log, each transaction is identified with an integer value and followed where appropriate with other values relevant to the transaction. To reduce the size of the log and remove any transactions that are no longer relevant, a copy of the log is kept by renaming the log at each time interval defined by configuration variable QUEUE_CLEAN_INTERVAL, and then a new log is written with only current and relevant transactions.
Configuration variables that affect the job queue log are
Configuration variables that affect the event log, setting details such as the maximum size to which this log may grow and details of file rotation and locking are
