Protocol agnostic (i.e. non-http, non-java specific) configs go hereProtocol agnostic methodsThe Elasticsearch action to perform. Valid actions are:

For more details on actions, check out the Elasticsearch bulk API documentation

HTTP Path to perform the _bulk requests tothis defaults to a concatenation of the path parameter and "_bulk"

The .cer or .pem file to validate the server’s certificate

Enable doc_as_upsert for update mode.Create a new document with source if document_id doesn’t exist in Elasticsearch

The document ID for the index. Useful for overwriting existing entries inElasticsearch with the same ID.

Note: This option is deprecated due to the removal of types in Elasticsearch 6.0.It will be removed in the next major version of Logstash.This sets the document type to write events to. Generally you should try to write onlysimilar events to the same type. String expansion %{foo} works here.If you don’t set a value for this option:

Set the Elasticsearch errors in the whitelist that you don’t want to log.A useful example is when you want to skip all 409 errorswhich are document_already_exists_exception.

Pass a set of key value pairs as the headers sent in each request toan elasticsearch node. The headers will be used for any kind of request(_bulk request, template installation, health checks and sniffing).These custom headers will be overidden by settings like http_compression.

HTTP Path where a HEAD request is sent when a backend is marked downthe request is sent in the background to see if it has come back againbefore it is once again eligible to service requests.If you have custom firewall rules you may need to change this

Sets the host(s) of the remote instance. If given an array it will load balance requests across the hosts specified in the hosts parameter.Remember the http protocol uses the http address (eg. 9200, not 9300). "127.0.0.1" ["127.0.0.1:9200","127.0.0.2:9200"] ["http://127.0.0.1"] ["https://127.0.0.1:9200"] ["https://127.0.0.1:9200/mypath"] (If using a proxy on a subpath)It is important to exclude dedicated master nodes from the hosts listto prevent LS from sending bulk requests to the master nodes. So this parameter should only reference either data or client nodes in Elasticsearch.

Any special characters present in the URLs here MUST be URL escaped! This means # should be put in as %23 for instance.

Enable gzip compression on requests. Note that response compression is on by default for Elasticsearch v5.0 and beyond

The default setting of auto will automatically enable the Index Lifecycle Management feature, if the Elasticsearch cluster is running Elasticsearch version 7.0.0 or higher with the ILM feature enabled, and disable it otherwise.

Setting this flag to false will disable the Index Lifecycle Management feature, even if the Elasticsearch cluster supports ILM.Setting this flag to true will enable Index Lifecycle Management feature, if the Elasticsearch cluster supports it. This is requiredto enable Index Lifecycle Management on a version of Elasticsearch earlier than version 7.0.0.

This feature requires a Basic License or above to be installed on an Elasticsearch cluster version 6.6.0 or later

Pattern used for generating indices managed by Index Lifecycle Management. The value specified in the pattern will be appended tothe write alias, and incremented automatically when a new index is created by ILM.

Date Math can be used when specifying an ilm pattern, see Rollover API docs for details

Updating the pattern will require the index template to be rewritten

The pattern must finish with a dash and a number that will be automatically incremented when indices rollover.

Modify this setting to use a custom Index Lifecycle Management policy, rather than the default. If this value is not set, the default policy willbe automatically installed into Elasticsearch

If this setting is specified, the policy must already exist in Elasticsearch cluster.

The rollover alias is the alias where indices managed using Index Lifecycle Management will be written to.

If both index and ilm_rollover_alias are specified, ilm_rollover_alias takes precedence.

Updating the rollover alias will require the index template to be rewritten

The index to write events to. This can be dynamic using the %{foo} syntax.The default value will partition your indices by day so you can more easilydelete old data or only search specific date ranges.Indexes may not contain uppercase characters.For weekly indexes ISO 8601 format is recommended, eg. logstash-%{+xxxx.ww}.LS uses Joda to format the index pattern from event timestamp.Joda formats are defined here.

The keystore used to present a certificate to the server.It can be either .jks or .p12

Set the keystore password

From Logstash 1.3 onwards, a template is applied to Elasticsearch duringLogstash’s startup if one with the name template_name does not already exist.By default, the contents of this template is the default template forlogstash-%{+YYYY.MM.dd} which always matches indices based on the patternlogstash-*. Should you require support for other index names, or would liketo change the mappings in the template in general, a custom template can bespecified by setting template to the path of a template file.

Setting manage_template to false disables this feature. If you require morecontrol over template creation, (e.g. creating indices dynamically based onfield names) you should set manage_template to false and use the RESTAPI to apply your templates manually.

Pass a set of key value pairs as the URL query string. This query string is addedto every host listed in the hosts configuration. If the hosts list containsurls that already have query strings, the one specified here will be appended.

For child documents, ID of the associated parent.This can be dynamic using the %{foo} syntax.

Password to authenticate to a secure Elasticsearch cluster

HTTP Path at which the Elasticsearch server lives. Use this if you must run Elasticsearch behind a proxy that remapsthe root path for the Elasticsearch HTTP API lives.Note that if you use paths as components of URLs in the hosts field you maynot also set this field. That will raise an error at startup

Set which ingest pipeline you wish to execute for an event. You can also use event dependent configurationhere like pipeline => "%{INGEST_PIPELINE}"

While the output tries to reuse connections efficiently we have a maximum.This sets the maximum number of open connections the output will create.Setting this too low may mean frequently closing / opening connectionswhich is bad.

While the output tries to reuse connections efficiently we have a maximum per endpoint.This sets the maximum number of open connections per endpoint the output will create.Setting this too low may mean frequently closing / opening connectionswhich is bad.

Set the address of a forward HTTP proxy.This used to accept hashes as arguments but now only acceptsarguments of the URI type to prevent leaking credentials.

How frequently, in seconds, to wait between resurrection attempts.Resurrection is the process by which backend endpoints marked down are checkedto see if they have come back to life

Set initial interval in seconds between bulk retries. Doubled on each retry up to retry_max_interval

Set max interval in seconds between bulk retries.

The number of times Elasticsearch should internally retry an update/upserted documentSee the partial updatesfor more info

A routing override to be applied to all processed events.This can be dynamic using the %{foo} syntax.

Set script name for scripted update mode

Example:

output {  elasticsearch {    script => "ctx._source.message = params.event.get('message')"  }}

Set the language of the used script. If not set, this defaults to painless in ES 5.0.When using indexed (stored) scripts on Elasticsearch 6 and higher, you must set this parameter to "" (empty string).

Define the type of script referenced by "script" variable inline : "script" contains inline script indexed : "script" contains the name of script directly indexed in elasticsearch file : "script" contains the name of script stored in elasticsearch’s config directory

Set variable name passed to script (scripted update)

if enabled, script is in charge of creating non-existent document (scripted update)

This setting asks Elasticsearch for the list of all cluster nodes and adds them to the hosts list.For Elasticsearch 1.x and 2.x any nodes with http.enabled (on by default) will be added to the hosts list, including master-only nodes!For Elasticsearch 5.x and 6.x any nodes with http.enabled (on by default) will be added to the hosts list, excluding master-only nodes.

How long to wait, in seconds, between sniffing attempts

HTTP Path to be used for the sniffing requeststhe default value is computed by concatenating the path value and "_nodes/http"if sniffing_path is set it will be used as an absolute pathdo not use full URL here, only paths, e.g. "/sniff/_nodes/http"

Enable SSL/TLS secured communication to Elasticsearch cluster. Leaving this unspecified will use whatever schemeis specified in the URLs listed in hosts. If no explicit protocol is specified plain HTTP will be used.If SSL is explicitly disabled here the plugin will refuse to start if an HTTPS URL is given in hosts

Option to validate the server’s certificate. Disabling this severely compromises security.For more information on disabling certificate verification please readhttps://www.cs.utexas.edu/~shmat/shmat_ccs12.pdf

You can set the path to your own template here, if you so desire.If not set, the included template will be used.

This configuration option defines how the template is named inside Elasticsearch.Note that if you have used the template management features and subsequentlychange this, you will need to prune the old template manually, e.g.

curl -XDELETE <http://localhost:9200/_template/OldTemplateName?pretty>

where OldTemplateName is whatever the former setting was.

The template_overwrite option will always overwrite the indicated templatein Elasticsearch with either the one indicated by template or the included one.This option is set to false by default. If you always want to stay up to datewith the template provided by Logstash, this option could be very useful to you.Likewise, if you have your own template file managed by puppet, for example, andyou wanted to be able to update it regularly, this option could help there as well.

Please note that if you are using your own customized version of the Logstashtemplate (logstash), setting this to true will make Logstash to overwritethe "logstash" template (i.e. removing all customized settings)

Set the timeout, in seconds, for network operations and requests sent Elasticsearch. Ifa timeout occurs, the request will be retried.

The truststore to validate the server’s certificate.It can be either .jks or .p12.Use either :truststore or :cacert.

Set the truststore password

Set upsert content for update mode.Create a new document with this parameter as json string if document_id doesn’t exists

Username to authenticate to a secure Elasticsearch cluster

How long to wait before checking if the connection is stale before executing a request on a connection using keepalive.You may want to set this lower, if you get connection errors regularlyQuoting the Apache commons docs (this client is based Apache Commmons):Defines period of inactivity in milliseconds after which persistent connections mustbe re-validated prior to being leased to the consumer. Non-positive value passed tothis method disables connection validation. This check helps detect connections thathave become stale (half-closed) while kept inactive in the pool.See these docs for more info

The version to use for indexing. Use sprintf syntax like %{my_version} to use a field value here.See https://www.elastic.co/blog/elasticsearch-versioning-support.

Disable or enable metric logging for this specific plugin instance.By default we record all the metrics we can, but you can disable metrics collectionfor a specific plugin.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one.It is strongly recommended to set this ID in your configuration. This is particularly usefulwhen you have two or more plugins of the same type. For example, if you have 2 elasticsearch outputs.Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

output {  elasticsearch {    id => "my_plugin_id"  }}
