plain encoding is special, because it does not validate or transform any input.
A list of regular expressions to match the lines that you want Filebeat to exclude. Filebeat drops any lines that match a regular expression in the list. By default, no lines are dropped. Empty lines are ignored.
If multiline settings are also specified, each multiline message
is combined into a single line before the lines are filtered by
The following example configures Filebeat to drop any lines that start with
filebeat.inputs: - type: stdin ... exclude_lines: ['^DBG']
See Regular expression support for a list of supported regexp patterns.
A list of regular expressions to match the lines that you want Filebeat to include. Filebeat exports only the lines that match a regular expression in the list. By default, all lines are exported. Empty lines are ignored.
If multiline settings also specified, each multiline message is
combined into a single line before the lines are filtered by
The following example configures Filebeat to export any lines that start
filebeat.inputs: - type: stdin ... include_lines: ['^ERR', '^WARN']
exclude_lines are defined, Filebeat
include_lines first and then executes
exclude_lines. The order in
which the two options are defined doesn’t matter. The
will always be executed before the
exclude_lines option, even if
exclude_lines appears before
include_lines in the config file.
The following example exports all log lines that contain
except for lines that begin with
DBG (debug messages):
filebeat.inputs: - type: stdin ... include_lines: ['sometext'] exclude_lines: ['^DBG']
See Regular expression support for a list of supported regexp patterns.
The size in bytes of the buffer that each harvester uses when fetching a file. The default is 16384.
The maximum number of bytes that a single log message can have. All bytes after
max_bytes are discarded and not sent. This setting is especially useful for
multiline log messages, which can get large. The default is 10MB (10485760).
These options make it possible for Filebeat to decode logs structured as JSON messages. Filebeat processes the logs line by line, so the JSON decoding only works if there is one JSON object per line.
The decoding happens before line filtering and multiline. You can combine JSON
decoding with filtering and multiline if you set the
message_key option. This
can be helpful in situations where the application logs are wrapped in JSON
objects, as with like it happens for example with Docker.
json.keys_under_root: true json.add_error_key: true json.message_key: log
You must specify at least one of the following settings to enable JSON parsing mode:
- By default, the decoded JSON is placed under a "json" key in the output document. If you enable this setting, the keys are copied top level in the output document. The default is false.
keys_under_rootand this setting are enabled, then the values from the decoded JSON object overwrite the fields that Filebeat normally adds (type, source, offset, etc.) in case of conflicts.
If this setting is enabled, Filebeat adds a
"error.message" and "error.type: json" key in case of JSON unmarshalling errors
or when a
message_keyis defined in the configuration but cannot be used.
- An optional configuration setting that specifies a JSON key on which to apply the line filtering and multiline settings. If specified the key must be at the top level in the JSON object and the value associated with the key must be a string, otherwise no filtering or multiline aggregation will occur.
Option configuration setting that specifies the JSON key to
set the document id. If configured, the field will be removed from the original
json document and stored in
- An optional configuration setting that specifies if JSON decoding errors should be logged or not. If set to true, errors will not be logged. The default is false.
Options that control how Filebeat deals with log messages that span multiple lines. See Multiline messages for more information about configuring multiline options.
The following configuration options are supported by all inputs.
enabled option to enable and disable inputs. By default, enabled is
set to true.
A list of tags that Filebeat includes in the
tags field of each published
event. Tags make it easy to select specific events in Kibana or apply
conditional filtering in Logstash. These tags will be appended to the list of
tags specified in the general configuration.
filebeat.inputs: - type: stdin . . . tags: ["json"]
Optional fields that you can specify to add additional information to the
output. For example, you might add fields that you can use for filtering log
data. Fields can be scalar values, arrays, dictionaries, or any nested
combination of these. By default, the fields that you specify here will be
grouped under a
fields sub-dictionary in the output document. To store the
custom fields as top-level fields, set the
fields_under_root option to true.
If a duplicate field is declared in the general configuration, then its value
will be overwritten by the value declared here.
filebeat.inputs: - type: stdin . . . fields: app_id: query_engine_12
If this option is set to true, the custom
fields are stored as top-level fields in
the output document instead of being grouped under a
fields sub-dictionary. If
the custom field names conflict with other field names added by Filebeat,
then the custom fields overwrite the other fields.
A list of processors to apply to the input data.
See Processors for information about specifying processors in your config.
The Ingest Node pipeline ID to set for the events generated by this input.
The pipeline ID can also be configured in the Elasticsearch output, but this option usually results in simpler configuration files. If the pipeline is configured both in the input and output, the option from the input is used.
If this option is set to true, fields with
null values will be published in
the output document. By default,
keep_null is set to
If present, this formatted string overrides the index for events from this input
(for elasticsearch outputs), or sets the
raw_index field of the event’s
metadata (for other outputs). This string can only refer to the agent name and
version and the event timestamp; for access to dynamic fields, use
output.elasticsearch.index or a processor.
