Redis input
editRedis input
editThis functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
Use the redis
input to read entries from Redis slowlogs.
Example configuration:
filebeat.inputs: - type: redis hosts: ["localhost:6379"] password: "${redis_pwd}"
Configuration options
editThe redis
input supports the following configuration options plus the
Common options described later.
hosts
editThe list of Redis hosts to connect to.
password
editThe password to use when connecting to Redis.
scan_frequency
editHow often Filebeat reads entries from Redis slowlogs. Specify 1s
to scan
Redis as frequently as possible without causing Filebeat to scan too
frequently. Do not set this value to less than 1s
.
The default is 10s
.
Redis slowlogs are not permanent. To ensure that all slowlog entries
are collected, set scan_frequency
to a value that allows Filebeat
sufficient time to connect to Redis, query the logs, and buffer them to the
output within the specified interval.
timeout
editHow long to wait for a response from Redis before the input returns an error.
The default is 1s
.
network
editThe network type to use for the Redis connection. Valid settings include: tcp
,
tcp4
, tcp6
, and unix
. The default is tcp
.
maxconn
editThe maximum number of concurrent connections. The default is 10
.
Common options
editThe following configuration options are supported by all inputs.
enabled
editUse the enabled
option to enable and disable inputs. By default, enabled is
set to true.
tags
editA 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.
Example:
filebeat.inputs: - type: redis . . . tags: ["json"]
fields
editOptional 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: redis . . . fields: app_id: query_engine_12
fields_under_root
editIf 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.
processors
editA list of processors to apply to the input data.
See Processors for information about specifying processors in your config.
pipeline
editThe ingest 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.
keep_null
editIf this option is set to true, fields with null
values will be published in
the output document. By default, keep_null
is set to false
.
index
editIf 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.
Example value: "%{[agent.name]}-myindex-%{+yyyy.MM.dd}"
might
expand to "filebeat-myindex-2019.11.01"
.
publisher_pipeline.disable_host
editBy default, all events contain host.name
. This option can be set to true
to
disable the addition of this field to all events. The default value is false
.
