Overview

The Datefile adapter is similar to the File adapter. However, it rotates the file at midnight (by default).

Instance Attribute Details

#date_pattern ⇒ Object

The pattern to be used for the files

Examples:

date_pattern = "%Y%m%d"       # default
date_pattern = "%Y-week-%V"


22
23
24
 
# File 'lib/yell/adapters/datefile.rb', line 22

def date_pattern
  @date_pattern
end

#header ⇒ Object

You can suppress the first line of the logfile that contains the metadata. This is important upon rollover, because on *nix systems, it is not possible to determine the creation time of a file, on the last access time. The header compensates this.

Examples:

header = false


50
51
52
 
# File 'lib/yell/adapters/datefile.rb', line 50

def header
  @header
end

#keep ⇒ Object

Set the amount of logfiles to keep when rolling over. By default, no files will be cleaned up.

Examples:

Keep the last 5 logfiles

keep = 5
keep = '10'

Do not clean up any files

keep = 0

# File 'lib/yell/adapters/datefile.rb', line 41

def keep
  @keep
end

#symlink ⇒ Object

Tell the adapter to create a symlink onto the currently active (timestamped) file. Upon rollover, the symlink is set to the newly created file, and so on.

Examples:

symlink = true


30
31
32
 
# File 'lib/yell/adapters/datefile.rb', line 30

def symlink
  @symlink
end
