Detailsedit

 

codecedit

  • Value type is codec
  • Default value is "plain"

The codec used for output data. Output codecs are a convenient method for encoding your data before it leaves the output, without needing a separate filter in your Logstash pipeline.

exclude_tags (DEPRECATED)edit

  • DEPRECATED WARNING: This configuration item is deprecated and may not be available in future versions.
  • Value type is array
  • Default value is []

Only handle events without any of these tags. Optional.

filename_failureedit

  • Value type is string
  • Default value is "_filepath_failures"

If the generated path is invalid, the events will be saved into this file and inside the defined path.

flush_intervaledit

  • Value type is number
  • Default value is 2

Flush interval (in seconds) for flushing writes to log files. 0 will flush on every message.

gzipedit

  • Value type is boolean
  • Default value is false

Gzip the output stream before writing to disk.

max_sizeedit

  • Value type is string
  • There is no default value for this setting.

The maximum size of file to write. When the file exceeds this threshold, it will be rotated to the current filename + ".1" If that file already exists, the previous .1 will shift to .2 and so forth.

NOT YET SUPPORTED

message_formatedit

  • Value type is string
  • There is no default value for this setting.

The format to use when writing events to the file. This value supports any string and can include %{name} and other dynamic strings.

If this setting is omitted, the full json representation of the event will be written as a single line.

pathedit

  • This is a required setting.
  • Value type is string
  • There is no default value for this setting.

The path to the file to write. Event fields can be used here, like /var/log/logstash/%{host}/%{application} One may also utilize the path option for date-based log rotation via the joda time format. This will use the event timestamp. E.g.: path => "./test-%{+YYYY-MM-dd}.txt" to create ./test-2013-05-29.txt

If you use an absolute path you cannot start with a dynamic string. E.g: /%{myfield}/, /test-%{myfield}/ are not valid paths

tags (DEPRECATED)edit

  • DEPRECATED WARNING: This configuration item is deprecated and may not be available in future versions.
  • Value type is array
  • Default value is []

Only handle events with all of these tags. Optional.

type (DEPRECATED)edit

  • DEPRECATED WARNING: This configuration item is deprecated and may not be available in future versions.
  • Value type is string
  • Default value is ""

The type to act on. If a type is given, then this output will only act on messages with the same type. See any input plugin’s type attribute for more. Optional.

workersedit

  • Value type is number
  • Default value is 1

The number of workers to use for this output. Note that this setting may not be useful for all outputs.
