Parse data using ingest pipelines
editParse data using ingest pipelines
editIngest pipelines preprocess and enrich APM documents before indexing them. For example, a pipeline might define one processor that removes a field, one that transforms a field, and another that renames a field.
The default APM pipelines are defined in Elasticsearch apm-data plugin index templates. Elasticsearch then uses the index pattern in these index templates to match pipelines to APM data streams.
Custom ingest pipelines
editElastic APM supports custom ingest pipelines. A custom pipeline allows you to transform data to better match your specific use case. This can be useful, for example, to ensure data security by removing or obfuscating sensitive information.
Each data stream ships with a default pipeline.
This default pipeline calls an initially non-existent and non-versioned "@custom" ingest pipeline.
If left uncreated, this pipeline has no effect on your data. However, if utilized,
this pipeline can be used for custom data processing, adding fields, sanitizing data, and more.
In addition, ingest pipelines can also be used to direct application metrics (metrics-apm.app.*) to a data stream with a different dataset, e.g. to combine metrics for two applications.
Sending other APM data to alternate data streams, like traces (traces-apm.*), logs (logs-apm.*), and internal metrics (metrics-apm.internal*) is not currently supported.
@custom ingest pipeline naming convention
edit@custom pipelines are specific to each data stream and follow a similar naming convention: <type>-<dataset>@custom.
As a reminder, the default APM data streams are:
-
Application traces:
traces-apm-<namespace> -
RUM and iOS agent application traces:
traces-apm.rum-<namespace> -
APM internal metrics:
metrics-apm.internal-<namespace> -
APM transaction metrics:
metrics-apm.transaction.<metricset.interval>-<namespace> -
APM service destination metrics:
metrics-apm.service_destination.<metricset.interval>-<namespace> -
APM service transaction metrics:
metrics-apm.service_transaction.<metricset.interval>-<namespace> -
APM service summary metrics:
metrics-apm.service_summary.<metricset.interval>-<namespace> -
Application metrics:
metrics-apm.app.<service.name>-<namespace> -
APM error/exception logging:
logs-apm.error-<namespace> -
APM app logging:
logs-apm.app.<service.name>-<namespace>
To match a custom ingest pipeline with a data stream, follow the <type>-<dataset>@custom template,
or replace -namespace with @custom in the table above.
For example, to target application traces, you’d create a pipeline named traces-apm@custom.
The @custom pipeline can directly contain processors or you can use the
pipeline processor to call other pipelines that can be shared across multiple data streams or integrations.
The @custom pipeline will persist across all version upgrades.
Create a @custom ingest pipeline
editThe process for creating a custom ingest pipeline is as follows:
- Create a pipeline with processors specific to your use case
-
Add the newly created pipeline to an
@custompipeline that matches an APM data stream
