Elasticsearch Destination Plugin
Elasticsearch is a search and analytics engine that is commonly used to store and analyze large volumes of machine-generated data, such as logs, metrics, and other telemetry data. The Elasticsearch Destination Plugin in Calyptia Core allows you to easily integrate your telemetry data with Elasticsearch, enabling you to store, search, and visualize your data using Elasticsearch's powerful indexing and querying capabilities.
With the Elasticsearch Output Plugin, you can configure your Calyptia Core pipeline to output your telemetry data to Elasticsearch.
This plugin provides a flexible and configurable way to transmit your data to Elasticsearch, allowing you to customize the indexing settings, document mappings, and other attributes of your data to suit your specific needs.

The following are Advanced configuration Parameters for Elasticsearch Destination Plugin.
| Key | Description |
|---|---|
Replace Dots | When enabled, replace field name dots with underscore, required by versions of Elasticsearch |
Type | Type Name |
Suppress Type Name | If true, mapping types are removed. for v7.0.0 or later |
Buffer Size | Specify the buffer size used to read the response from the Elasticsearch HTTP service. This option is useful for debugging purposes where is required to read full responses, note that 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 |
Path | Elasticsearch accepts new data on HTTP query path '/_bulk'. But it is also possible to serve Elasticsearch behind a reverse proxy on a subpath. This option defines such path on the fluent-bit side. It simply adds a path prefix in the indexing HTTP POST URI |
Pipeline | Newer versions of Elasticsearch allows to setup filters called pipelines. This option allows to define which pipeline the database should use. For performance reasons is strongly suggested to do parsing and filtering on Fluent Bit side, avoid pipelines |
Generate ID | When enabled, generate _id for outgoing records. This prevents duplicate records when retrying ES |
Write Operation | Operation to use to write in bulk requests |
ID Key | If set, _id will be the value of the key from incoming record. |
Replace Dots | Use current time for index generation instead of message record |
Logstash Prefix | When Logstash_Format is enabled, the Index name is composed using a prefix and the date, e.g: If Logstash_Prefix is equals to 'mydata' your index will become 'mydata-YYYY.MM.DD'. The last string appended belongs to the date when the data is being generated' |
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 is not found in the record then the Logstash_Prefix option will act as a fallback. Nested keys are supported through record accessor pattern |
Logstash Date Format | Time format (based on strftime) to generate the second part of the Index name |
Time Key | When Logstash_Format is enabled, each record will get a new timestamp field. The Time_Key property defines the name of that field |
Time Key Format | When Logstash_Format is enabled, this property defines the format of the timestamp |
Time Key Nanos | When Logstash_Format is enabled, enabling this property sends nanosecond precision timestamps |
Include Tag Key | When enabled, it append the Tag name to the record |
Tag Key | When Include_Tag_key is enabled, this property defines the key name of the tag in the message |
The following are Basic Authentication configuration Parameters for Elasticsearch Destination Plugin.
| Key | Description |
|---|---|
HTTP Username | Basic Auth Username |
HTTP Password | Basic Auth Password. Requires HTTP_User to be set |
The following are AWS Authentication configuration Parameters for Elasticsearch Destination Plugin.
| Key | Description |
|---|---|
Enable AWS Authentication | Enable AWS Sigv4 Authentication |
AWS Region | AWS Region of your service |
AWS STS Endpoint | Custom endpoint for the AWS STS API, used with the AWS_Role_ARN option |
AWS IAM Assume Role | ARN of an IAM role to assume (ex. for cross-account access) |
AWS External ID | Specify an external ID for the STS API, can be used with the |
The following are Elastic Cloud Authentication configuration Parameters for Elasticsearch Destination Plugin.
| Key | Description |
|---|---|
Elastic Cloud ID | Elastic cloud ID of the cluster to connect to |
Elastic Cloud Authentication Credentials | Elastic cloud authentication credentials |
The following are Advanced Networking configuration Parameters for Elasticsearch Destination Plugin.
| Key | Description |
|---|---|
DNS Mode | Select the primary DNS connection type (TCP or UDP) |
DNS Resolver | Select the primary DNS connection type (TCP or UDP) |
Prefer IPv4 | Prioritize IPv4 DNS results when trying to establish a connection |
Keepalive | Enable or disable Keepalive support |
Keepalive Idle Timeout | Set maximum time allowed for an idle Keepalive connection |
Max Connect Timeout | Set maximum time allowed to establish a connection, this time includes the TLS handshake |
Max Connect Timeout Log Error | On connection timeout, specify if it should log an error. When disabled, the timeout is logged as a debug message |
Max Keepalive Recycle | Set maximum number of times a keepalive connection can be used before it is retired. |
Source Address | Specify network address to bind for data traffic |
The following are Debugging configuration Parameters for Elasticsearch Destination Plugin.
