# POST /v2/entries:tail

`POST /v2/entries:tail`

Streaming read of log entries as they are received. Until the stream is terminated, it will continue reading logs.

## Request body

- TailLogEntriesRequest — The parameters to TailLogEntries.
  - `bufferWindow` string, google-duration — Optional. The amount of time to buffer log entries at the server before being returned to prevent out of order results due to late arriving log entries. Valid values are between 0-60000 milliseconds. Defaults to 2000 milliseconds.
  - `filter` string — Optional. A filter that chooses which log entries to return. For more information, see Logging query language (https://docs.cloud.google.com/logging/docs/view/logging-query-language).Only log entries that match the filter are returned. An empty filter matches all log entries in the resources listed in resource_names. Referencing a parent resource that is not listed in resource_names will cause the filter to return no results. The maximum length of a filter is 20,000 characters.
  - `resourceNames` string[] — Required. Name of a parent resource from which to retrieve log entries: projects/[PROJECT_ID] organizations/[ORGANIZATION_ID] billingAccounts/[BILLING_ACCOUNT_ID] folders/[FOLDER_ID]May alternatively be one or more views: projects/[PROJECT_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID] organizations/[ORGANIZATION_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID] billingAccounts/[BILLING_ACCOUNT_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID] folders/[FOLDER_ID]/locations/[LOCATION_ID]/buckets/[BUCKET_ID]/views/[VIEW_ID]
