Update existing data

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

For 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 accordingly.
