Hi Elasticians,
I've created pipeline `pipeline_add_ingest_timestamp`. I would like to achieve add time of ingesting by elasticsearch to the document using this pipeline. What am I doing wrong? The field is not populate to the document using this pipeline:
```
PUT _ingest/pipeline/pipeline_add_ingest_timestamp
{
"description": "Adds event.ingested field which represents time of ingestion.",
"processors": [
{
"set": {
"field": "event.ingested",
"value": "{{_ingest.timestamp}}"
}
}
]
}
```
```
GET _ingest/pipeline
```
```
"pipeline_add_ingest_timestamp" : {
"description" : "Adds event.ingested field which represents time of ingestion.",
"processors" : [
{
"set" : {
"field" : "event.ingested",
"value" : "{{_ingest.timestamp}}"
}
}
]
}
```

Your ingest pipeline looks good, I copied it to my own Kibana and used the [Simulate pipeline API](https://www.elastic.co/guide/en/elasticsearch/reference/7.8/simulate-pipeline-api.html) to test it - and it resulted in an event.ingested field with a timestamp in each document.
So I assume your problem is how to trigger the pipeline when you index new documents? For that you need to supply the **pipeline** -parameter with the name of your pipeline. Let's say you name it "my\_timestamp\_pipeline" then you need to index new documents like this:
```
PUT my-index/_doc/my-id?pipeline=my_timestamp_pipeline
{
"foo": "bar"
}
```
If you use a specific programming language on the client side (Perl, PHP, Python etc) you'll need to look up the documentation for that language to learn how to add the pipeline-parameter with each indexing request.
For more info see the [Ingest node documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/ingest.html).

Thank you @Bernt_Rostad. I've had missing parameter `pipeline` in Logstash configuration of **logstash-output-elasticsearch** plugin. Now it works.
Thank you!
