Advanced
| Name | Key | Description | Default |
|---|---|---|---|
| Replace Dots | replace_dots | When enabled, replaces field name dots with underscore, required by versions of OpenSearch. Accepted values: true, false. | false |
| Type | type | Type Name. | _doc |
| Suppress Type Name | suppress_type_name | If true, mapping types are removed. For v7.0.0 or later. Accepted values: true, false. | true |
| Buffer Size | buffer_size | Specifies 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 specification | 512k |
| Path | path | OpenSearch 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 ID | generate_id | When enabled, generates _id for outgoing records. This prevents duplicate records when retrying ES. Accepted values: true, false. | false |
| Write Operation | write_operation | Operation to use to write in bulk requests. | create |
| ID Key | id_key | If set, _id will be the value of the key from incoming records. | none |
| Replace Dots | current_time_index | Uses the current time for index generation instead of the message record. Accepted values: true, false. | false |
| Logstash Prefix | logstash_prefix | When 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 Key | logstash_prefix_key | When 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 Format | logstash_dateformat | Time format (based on strftime) to generate the second part of the index name. | %Y.%m.%d |
| Time Key | time_key | When logstash_format is enabled, each record gets a new timestamp field. The time_key property defines the name of that field. | @timestamp |
| Time Key | time_key_format | When logstash_format is enabled, this property defines the format of the timestamp. | none |
| Time Key Nanos | time_key_nanos | When logstash_format is enabled, enabling this property sends nanosecond precision timestamps. Accepted values: true, false. | false |
| Include Tag Key | inclulde_tag_key | When enabled, it appends the tag name to the record. Accepted values: true, false. | false |
| Tag Key | tag_key | When inclulde_tag_key is enabled, this property defines the key name of the tag in the message. | flb-key |
