Update existing data

You might want to update documents that are already indexed. For example, if you your service name was set incorrectly.

To do this, you can use the Update By Query API.

Rename a service

To rename a service, send the following request:

POST /apm-*/_update_by_query
{
  "query": {
    "term": {
      "context.service.name": {
        "value": "old-service-name"
      }
    }
  },
  "script": {
    "source": "ctx._source.context.service.name = 'new-service-name'",
    "lang": "painless"
  }
}

Remember to also change the service name in the APM agent configuration.
