The error_log file lists messages from the scheduler - errors, warnings, etc. The LogLevel directive controls which messages are logged:

level date-time message

The level field contains the type of message:

• A - Alert message (LogLevel alert)
• C - Critical error message (LogLevel crit)
• D - Debugging message (LogLevel debug)
• d - Detailed debugging message (LogLevel debug2)
• E - Normal error message (LogLevel error)
• I - Informational message (LogLevel info)
• N - Notice message (LogLevel notice)
• W - Warning message (LogLevel warn)
• X - Emergency error message (LogLevel emerg)

The date-time field contains the date and time of when the page started printing. The format of this field is identical to the data-time field in the access_log file.

The message fields contains a free-form textual message. Messages from job filters are prefixed with "[Job NNN]".
