======================== Elasticsearch Configuration =========================

NOTE: Elasticsearch comes with reasonable defaults for most settings.

Before you set out to tweak and tune the configuration, make sure you

understand what are you trying to accomplish and the consequences.

The primary way of configuring a node is via this file. This template lists

the most important settings you may want to configure for a production cluster.

Please consult the documentation for further information on configuration options:

Elasticsearch Guide | Elastic

---------------------------------- Cluster -----------------------------------

Use a descriptive name for your cluster:

#cluster.name: my-application

------------------------------------ Node ------------------------------------

Use a descriptive name for the node:

#node.name: node-1

Add custom attributes to the node:

#node.attr.rack: r1

----------------------------------- Paths ------------------------------------

Path to directory where to store the data (separate multiple locations by comma):

#path.data: /path/to/data

Path to log files:

#path.logs: /path/to/logs

----------------------------------- Memory -----------------------------------

Lock the memory on startup:

#bootstrap.memory_lock: true

Make sure that the heap size is set to about half the memory available

on the system and that the owner of the process is allowed to use this

limit.

Elasticsearch performs poorly when the system is swapping the memory.

---------------------------------- Network -----------------------------------

By default Elasticsearch is only accessible on localhost. Set a different

address here to expose this node on the network:

#network.host: 192.168.0.1

By default Elasticsearch listens for HTTP traffic on the first free port it

finds starting at 9200. Set a specific HTTP port here:

#http.port: 9200

For more information, consult the network module documentation.

--------------------------------- Discovery ----------------------------------

Pass an initial list of hosts to perform discovery when this node is started:

The default list of hosts is ["127.0.0.1", "[::1]"]

#discovery.seed_hosts: ["host1", "host2"]

Bootstrap the cluster using an initial set of master-eligible nodes:

#cluster.initial_master_nodes: ["node-1", "node-2"]

For more information, consult the discovery and cluster formation module documentation.

--------------------------------- Readiness ----------------------------------

Enable an unauthenticated TCP readiness endpoint on localhost

#readiness.port: 9399

---------------------------------- Various -----------------------------------

Allow wildcard deletion of indices:

#action.destructive_requires_name: false

#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------

The following settings, TLS certificates, and keys have been automatically

generated to configure Elasticsearch security features on 31-08-2022 18:36:51

--------------------------------------------------------------------------------

Enable security features

xpack.security.enabled: true

xpack.security.enrollment.enabled: true

Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents

xpack.security.http.ssl:

enabled: true

keystore.path: certs/http.p12

Enable encryption and mutual authentication between cluster nodes

xpack.security.transport.ssl:

enabled: true

verification_mode: certificate

keystore.path: certs/transport.p12

truststore.path: certs/transport.p12

Create a new cluster with the current node only

Additional nodes can still join the cluster later

cluster.initial_master_nodes: ["LAPTOP-7MJ794OO"]

Allow HTTP API connections from anywhere

Connections are encrypted and require user authentication

http.host: 0.0.0.0

Allow other nodes to join the cluster from anywhere

Connections are encrypted and mutually authenticated

#transport.host: 0.0.0.0

#----------------------- END SECURITY AUTO CONFIGURATION -------------------------

kibana.yml

For more configuration options see the configuration guide for Kibana in

Welcome to Elastic Docs | Elastic

=================== System: Kibana Server ===================

Kibana is served by a back end server. This setting specifies the port to use.

#server.port: 5601

Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.

The default is 'localhost', which usually means remote machines will not be able to connect.

To allow connections from remote users, set this parameter to a non-loopback address.

#server.host: "localhost"

Enables you to specify a path to mount Kibana at if you are running behind a proxy.

Use the server.rewriteBasePath setting to tell Kibana if it should remove the basePath

from requests it receives, and to prevent a deprecation warning at startup.

This setting cannot end in a slash.

#server.basePath: ""

Specifies whether Kibana should rewrite requests that are prefixed with

server.basePath or require that they are rewritten by your reverse proxy.

Defaults to false.

#server.rewriteBasePath: false

Specifies the public URL at which Kibana is available for end users. If

server.basePath is configured this URL should end with the same basePath.

#server.publicBaseUrl: ""

The maximum payload size in bytes for incoming server requests.

#server.maxPayload: 1048576

The Kibana server's name. This is used for display purposes.

#server.name: "your-hostname"

=================== System: Kibana Server (Optional) ===================

Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.

These settings enable SSL for outgoing requests from the Kibana server to the browser.

#server.ssl.enabled: false

#server.ssl.certificate: /path/to/your/server.crt

#server.ssl.key: /path/to/your/server.key

=================== System: Elasticsearch ===================

The URLs of the Elasticsearch instances to use for all your queries.

#elasticsearch.hosts: ["http://localhost:9200"]

If your Elasticsearch is protected with basic authentication, these settings provide

the username and password that the Kibana server uses to perform maintenance on the Kibana

index at startup. Your Kibana users still need to authenticate with Elasticsearch, which

is proxied through the Kibana server.

#elasticsearch.username: "kibana_system"

#elasticsearch.password: "pass"

Kibana can also authenticate to Elasticsearch via "service account tokens".

Service account tokens are Bearer style tokens that replace the traditional username/password based configuration.

Use this token instead of a username/password.

elasticsearch.serviceAccountToken: "my_token"

Time in milliseconds to wait for Elasticsearch to respond to pings. Defaults to the value of

the elasticsearch.requestTimeout setting.

#elasticsearch.pingTimeout: 1500

Time in milliseconds to wait for responses from the back end or Elasticsearch. This value

must be a positive integer.

#elasticsearch.requestTimeout: 30000

The maximum number of sockets that can be used for communications with elasticsearch.

Defaults to Infinity.

#elasticsearch.maxSockets: 1024

Specifies whether Kibana should use compression for communications with elasticsearch

Defaults to false.

#elasticsearch.compression: false

List of Kibana client-side headers to send to Elasticsearch. To send no client-side

headers, set this value to (an empty list).

#elasticsearch.requestHeadersWhitelist: [ authorization ]

Header names and values that are sent to Elasticsearch. Any custom headers cannot be overwritten

by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration.

#elasticsearch.customHeaders: {}

Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable.

#elasticsearch.shardTimeout: 30000

=================== System: Elasticsearch (Optional) ===================

These files are used to verify the identity of Kibana to Elasticsearch and are required when

xpack.security.http.ssl.client_authentication in Elasticsearch is set to required.

#elasticsearch.ssl.certificate: /path/to/your/client.crt

#elasticsearch.ssl.key: /path/to/your/client.key

Enables you to specify a path to the PEM file for the certificate

authority for your Elasticsearch instance.

#elasticsearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ]

To disregard the validity of SSL certificates, change this setting's value to 'none'.

#elasticsearch.ssl.verificationMode: full

=================== System: Logging ===================

Set the value of this setting to off to suppress all logging output, or to debug to log everything. Defaults to 'info'

#logging.root.level: debug

Enables you to specify a file where Kibana stores log output.

#logging.appenders.default:

type: file

fileName: /var/logs/kibana.log

layout:

type: json

Logs queries sent to Elasticsearch.

#logging.loggers:

- name: elasticsearch.query

level: debug

Logs http responses.

#logging.loggers:

- name: http.server.response

level: debug

Logs system usage information.

#logging.loggers:

- name: metrics.ops

level: debug

=================== System: Other ===================

The path where Kibana stores persistent data not saved in Elasticsearch. Defaults to data

#path.data: data

Specifies the path where Kibana creates the process ID file.

#pid.file: /run/kibana/kibana.pid

Set the interval in milliseconds to sample system and process performance

metrics. Minimum is 100ms. Defaults to 5000ms.

#ops.interval: 5000

Specifies locale to be used for all localizable strings, dates and number formats.

Supported languages are the following: English (default) "en", Chinese "zh-CN", Japanese "ja-JP", French "fr-FR".

#i18n.locale: "en"

=================== Frequently used (Optional)===================

=================== Saved Objects: Migrations ===================

Saved object migrations run at startup. If you run into migration-related issues, you might need to adjust these settings.

The number of documents migrated at a time.

If Kibana can't start up or upgrade due to an Elasticsearch circuit_breaking_exception,

use a smaller batchSize value to reduce the memory pressure. Defaults to 1000 objects per batch.

#migrations.batchSize: 1000

The maximum payload size for indexing batches of upgraded saved objects.

To avoid migrations failing due to a 413 Request Entity Too Large response from Elasticsearch.

This value should be lower than or equal to your Elasticsearch cluster’s http.max_content_length

configuration option. Default: 100mb

#migrations.maxBatchSizeBytes: 100mb

The number of times to retry temporary migration failures. Increase the setting

if migrations fail frequently with a message such as `Unable to complete the [...] step after

15 attempts, terminating`. Defaults to 15

#migrations.retryAttempts: 15

=================== Search Autocomplete ===================

Time in milliseconds to wait for autocomplete suggestions from Elasticsearch.

This value must be a whole number greater than zero. Defaults to 1000ms

#unifiedSearch.autocomplete.valueSuggestions.timeout: 1000

Maximum number of documents loaded by each shard to generate autocomplete suggestions.

This value must be a whole number greater than zero. Defaults to 100_000

#unifiedSearch.autocomplete.valueSuggestions.terminateAfter: 100000

This section was automatically generated during setup.

logstash.yml

Settings file in YAML

Settings can be specified either in hierarchical form, e.g.:

pipeline:

batch:

size: 125

delay: 5

Or as flat keys:

pipeline.batch.size: 125

pipeline.batch.delay: 5

------------ Node identity ------------

Use a descriptive name for the node:

node.name: test

If omitted the node name will default to the machine's host name

------------ Data path ------------------

Which directory should be used by logstash and its plugins

for any persistent needs. Defaults to LOGSTASH_HOME/data

path.data:

------------ Pipeline Settings --------------

The ID of the pipeline.

pipeline.id: main

Set the number of workers that will, in parallel, execute the filters+outputs

stage of the pipeline.

This defaults to the number of the host's CPU cores.

pipeline.workers: 2

How many events to retrieve from inputs before sending to filters+workers

pipeline.batch.size: 125

How long to wait in milliseconds while polling for the next event

before dispatching an undersized batch to filters+outputs

pipeline.batch.delay: 50

Force Logstash to exit during shutdown even if there are still inflight

events in memory. By default, logstash will refuse to quit until all

received events have been pushed to the outputs.

WARNING: Enabling this can lead to data loss during shutdown

pipeline.unsafe_shutdown: false

Set the pipeline event ordering. Options are "auto" (the default), "true" or "false".

"auto" automatically enables ordering if the 'pipeline.workers' setting

is also set to '1', and disables otherwise.

"true" enforces ordering on the pipeline and prevent logstash from starting

if there are multiple workers.

"false" disables any extra processing necessary for preserving ordering.

pipeline.ordered: auto

Sets the pipeline's default value for ecs_compatibility, a setting that is

available to plugins that implement an ECS Compatibility mode for use with

the Elastic Common Schema.

Possible values are:

- disabled

- v1

- v8 (default)

Pipelines defined before Logstash 8 operated without ECS in mind. To ensure a

migrated pipeline continues to operate as it did before your upgrade, opt-OUT

of ECS for the individual pipeline in its pipelines.yml definition. Setting

it here will set the default for all pipelines, including new ones.

pipeline.ecs_compatibility: v8

------------ Pipeline Configuration Settings --------------

Where to fetch the pipeline configuration for the main pipeline

path.config:

Pipeline configuration string for the main pipeline

config.string:

At startup, test if the configuration is valid and exit (dry run)

config.test_and_exit: false

Periodically check if the configuration has changed and reload the pipeline

This can also be triggered manually through the SIGHUP signal

config.reload.automatic: false

How often to check if the pipeline configuration has changed (in seconds)

Note that the unit value (s) is required. Values without a qualifier (e.g. 60)

are treated as nanoseconds.

Setting the interval this way is not recommended and might change in later versions.

config.reload.interval: 3s

Show fully compiled configuration as debug log message

NOTE: --log.level must be 'debug'

config.debug: false

When enabled, process escaped characters such as \n and " in strings in the

pipeline configuration files.

config.support_escapes: false

------------ API Settings -------------

Define settings related to the HTTP API here.

The HTTP API is enabled by default. It can be disabled, but features that rely

on it will not work as intended.

api.enabled: true

By default, the HTTP API is not secured and is therefore bound to only the

host's loopback interface, ensuring that it is not accessible to the rest of

the network.

When secured with SSL and Basic Auth, the API is bound to all interfaces

unless configured otherwise.

api.http.host: 127.0.0.1

The HTTP API web server will listen on an available port from the given range.

Values can be specified as a single port (e.g., 9600), or an inclusive range

of ports (e.g., 9600-9700).

api.http.port: 9600-9700

The HTTP API includes a customizable "environment" value in its response,

which can be configured here.

api.environment: "production"

The HTTP API can be secured with SSL (TLS). To do so, you will need to provide

the path to a password-protected keystore in p12 or jks format, along with credentials.

api.ssl.enabled: false

api.ssl.keystore.path: /path/to/keystore.jks

api.ssl.keystore.password: "y0uRp4$$w0rD"

The HTTP API can be configured to require authentication. Acceptable values are

- none: no auth is required (default)

- basic: clients must authenticate with HTTP Basic auth, as configured

with api.auth.basic.* options below

api.auth.type: none

When configured with api.auth.type basic, you must provide the credentials

that requests will be validated against. Usage of Environment or Keystore

variable replacements is encouraged (such as the value "${HTTP_PASS}", which

resolves to the value stored in the keystore's HTTP_PASS variable if present

or the same variable from the environment)

api.auth.basic.username: "logstash-user"

api.auth.basic.password: "s3cUreP4$$w0rD"

When setting api.auth.basic.password, the password should meet

the default password policy requirements.

The default password policy requires non-empty minimum 8 char string that

includes a digit, upper case letter and lower case letter.

Policy mode sets Logstash to WARN or ERROR when HTTP authentication password doesn't

meet the password policy requirements.

The default is WARN. Setting to ERROR enforces stronger passwords (recommended).

api.auth.basic.password_policy.mode: WARN

------------ Module Settings ---------------

Define modules here. Modules definitions must be defined as an array.

The simple way to see this is to prepend each name with a -, and keep

all associated variables under the name they are associated with, and

above the next, like this:

modules:

- name: MODULE_NAME

var.PLUGINTYPE1.PLUGINNAME1.KEY1: VALUE

var.PLUGINTYPE1.PLUGINNAME1.KEY2: VALUE

var.PLUGINTYPE2.PLUGINNAME1.KEY1: VALUE

var.PLUGINTYPE3.PLUGINNAME3.KEY1: VALUE

Module variable names must be in the format of

var.PLUGIN_TYPE.PLUGIN_NAME.KEY

modules:

------------ Cloud Settings ---------------

Define Elastic Cloud settings here.

Format of cloud.id is a base64 value e.g. dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyRub3RhcmVhbCRpZGVudGlmaWVy

and it may have an label prefix e.g. staging:dXMtZ...

This will overwrite 'var.elasticsearch.hosts' and 'var.kibana.host'

cloud.id:

Format of cloud.auth is: :

This is optional

If supplied this will overwrite 'var.elasticsearch.username' and 'var.elasticsearch.password'

If supplied this will overwrite 'var.kibana.username' and 'var.kibana.password'

cloud.auth: elastic:

------------ Queuing Settings --------------

Internal queuing model, "memory" for legacy in-memory based queuing and

"persisted" for disk-based acked queueing. Defaults is memory

queue.type: memory

If queue.type: persisted, the directory path where the pipeline data files will be stored.

Each pipeline will group its PQ files in a subdirectory matching its pipeline.id.

Default is path.data/queue.

path.queue:

If using queue.type: persisted, the page data files size. The queue data consists of

append-only data files separated into pages. Default is 64mb

queue.page_capacity: 64mb

If using queue.type: persisted, the maximum number of unread events in the queue.

Default is 0 (unlimited)

queue.max_events: 0

If using queue.type: persisted, the total capacity of the queue in number of bytes.

If you would like more unacked events to be buffered in Logstash, you can increase the

capacity using this setting. Please make sure your disk drive has capacity greater than

the size specified here. If both max_bytes and max_events are specified, Logstash will pick

whichever criteria is reached first

Default is 1024mb or 1gb

queue.max_bytes: 1024mb

If using queue.type: persisted, the maximum number of acked events before forcing a checkpoint

Default is 1024, 0 for unlimited

queue.checkpoint.acks: 1024

If using queue.type: persisted, the maximum number of written events before forcing a checkpoint

Default is 1024, 0 for unlimited

queue.checkpoint.writes: 1024

If using queue.type: persisted, the interval in milliseconds when a checkpoint is forced on the head page

Default is 1000, 0 for no periodic checkpoint.

queue.checkpoint.interval: 1000

------------ Dead-Letter Queue Settings --------------

Flag to turn on dead-letter queue.

dead_letter_queue.enable: false

If using dead_letter_queue.enable: true, the maximum size of each dead letter queue. Entries

will be dropped if they would increase the size of the dead letter queue beyond this setting.

Default is 1024mb

dead_letter_queue.max_bytes: 1024mb

If using dead_letter_queue.enable: true, the interval in milliseconds where if no further events eligible for the DLQ

have been created, a dead letter queue file will be written. A low value here will mean that more, smaller, queue files

may be written, while a larger value will introduce more latency between items being "written" to the dead letter queue, and

being available to be read by the dead_letter_queue input when items are written infrequently.

Default is 5000.

dead_letter_queue.flush_interval: 5000

If using dead_letter_queue.enable: true, controls which entries should be dropped to avoid exceeding the size limit.

Set the value to drop_newer (default) to stop accepting new events that would push the DLQ size over the limit.

Set the value to drop_older to remove queue pages containing the oldest events to make space for new ones.

dead_letter_queue.storage_policy: drop_newer

If using dead_letter_queue.enable: true, the interval that events have to be considered valid. After the interval has

expired the events could be automatically deleted from the DLQ.

The interval could be expressed in days, hours, minutes or seconds, using as postfix notation like 5d,

to represent a five days interval.

The available units are respectively d, h, m, s for day, hours, minutes and seconds.

If not specified then the DLQ doesn't use any age policy for cleaning events.

dead_letter_queue.retain.age: 1d

If using dead_letter_queue.enable: true, defines the action to take when the dead_letter_queue.max_bytes is reached,

could be "drop_newer" or "drop_older".

With drop_newer, messages that were inserted most recently are dropped, logging an error line.

With drop_older setting, the oldest messages are dropped as new ones are inserted.

Default value is "drop_newer".

dead_letter_queue.storage_policy: drop_newer

If using dead_letter_queue.enable: true, the directory path where the data files will be stored.

Default is path.data/dead_letter_queue

path.dead_letter_queue:

------------ Debugging Settings --------------

Options for log.level:

* fatal

* error

* warn

* info (default)

* debug

* trace

log.level: info

path.logs:

------------ Other Settings --------------

Allow or block running Logstash as superuser (default: true)

allow_superuser: false

Where to find custom plugins

path.plugins:

Flag to output log lines of each pipeline in its separate log file. Each log filename contains the pipeline.name

Default is false

pipeline.separate_logs: false
