TELEMETRY PIPELINE
OpenSearch

OpenSearch destination plugin

The OpenSearch destination plugin lets you configure Chronosphere Telemetry Pipeline to send your data to OpenSearch.

Supported telemetry types

This plugin supports these telemetry types:

LogsMetricsTraces

Configuration parameters

Use the parameters in this section to configure your plugin. The Telemetry Pipeline web interface uses the values in the Name column to describe the parameters. Items in the Key column are the YAML keys to use in pipeline configuration files.

Advanced

NameKeyDescriptionDefault
Replace Dotsreplace_dotsWhen enabled, replace field name dots with underscore, required by versions of OpenSearch. Accepted values: true, false.false
TypetypeType Name._doc
Suppress Type Namesuppress_type_nameIf true, mapping types are removed. For v7.0.0 or later. Accepted values: true, false.true
Buffer Sizebuffer_sizeSpecify the buffer size used to read the response from the OpenSearch HTTP service. This option is useful for debugging purposes where is required to read full responses. Response size grows depending of the number of records inserted. To set an unlimited amount of memory set this value to false, otherwise the value must be according to the Unit Size specification512k
PathpathOpenSearch accepts new data on HTTP query path /_bulk. It's also possible to serve Elasticsearch behind a reverse proxy on a sub path. This option defines such path on the Telemetry Pipeline side. It adds only a path prefix in the indexing HTTP POST URI.none
Generate IDgenerate_idWhen enabled, generate _id for outgoing records. This prevents duplicate records when retrying ES. Accepted values: true, false.false
Write Operationwrite_operationOperation to use to write in bulk requests.create
ID Keyid_keyIf set, _id will be the value of the key from incoming records.none
Replace Dotscurrent_time_indexUse the current time for index generation instead of the message record. Accepted values: true, false.false
Logstash Prefixlogstash_prefixWhen logstash_format is enabled, the index name is composed using a prefix and the date. For example, if logstash_prefix is mydata, your index becomes mydata-YYYY.MM.DD. The last string appended belongs to the date when the data is being generated.none
Logstash Prefix Keylogstash_prefix_keyWhen included, the value in the record that belongs to the key will be looked up and over-write the logstash_prefix for index generation. If the key/value isn't found in the record, the logstash_prefix option acts as a fallback. Nested keys are supported through record accessor patterns.none
Logstash Date Formatlogstash_dateformatTime format (based on strftime) to generate the second part of the index name.%Y.%m.%d
Time Keytime_keyWhen logstash_format is enabled, each record gets a new timestamp field. The time_key property defines the name of that field.@timestamp
Time Keytime_key_formatWhen logstash_format is enabled, this property defines the format of the timestamp.none
Time Key Nanostime_key_nanosWhen logstash_format is enabled, enabling this property sends nanosecond precision timestamps. Accepted values: true, false.false
Include Tag Keyinclulde_tag_keyWhen enabled, it append the tag name to the record. Accepted values: true, false.false
Tag Keytag_keyWhen inclulde_tag_key is enabled, this property defines the key name of the tag in the message.flb-key
