gRPC Access Log Service (ALS)

This documentation is for the Envoy v3 API.

As of Envoy v1.18 the v2 API has been removed and is no longer supported.

If you are upgrading from v2 API config you may wish to view the v2 API documentation:

service/accesslog/v2/als.proto

service.accesslog.v3.StreamAccessLogsResponse

Empty response for the StreamAccessLogs API. Will never be sent. See below.

Stream message for the StreamAccessLogs API. Envoy will open a stream to the server and stream access logs without ever expecting a response.

{
  "identifier": "{...}",
  "http_logs": "{...}",
  "tcp_logs": "{...}"
}

identifier

(service.accesslog.v3.StreamAccessLogsMessage.Identifier) Identifier data that will only be sent in the first message on the stream. This is effectively structured metadata and is a performance optimization.

http_logs

(service.accesslog.v3.StreamAccessLogsMessage.HTTPAccessLogEntries) Batches of log entries of a single type. Generally speaking, a given stream should only ever include one type of log entry.

Precisely one of http_logs, tcp_logs must be set.

tcp_logs

(service.accesslog.v3.StreamAccessLogsMessage.TCPAccessLogEntries) Batches of log entries of a single type. Generally speaking, a given stream should only ever include one type of log entry.

Precisely one of http_logs, tcp_logs must be set.

{
  "node": "{...}",
  "log_name": "..."
}

node

(config.core.v3.Node, REQUIRED) The node sending the access log messages over the stream.

log_name

(string, REQUIRED) The friendly name of the log configured in CommonGrpcAccessLogConfig.

Wrapper for batches of HTTP access log entries.

{
  "log_entry": []
}

log_entry

Wrapper for batches of TCP access log entries.

{
  "log_entry": []
}
