RPC

This article explains how Fluentd handles HTTP RPC.

Overview

HTTP RPC is one way of managing fluentd instance. Several provided RPCs are replacement of signals. The response body is JSON format.

On signal unsupported environment, e.g. Windows, you can use RPC instead of signals.

Configuration

RPC is off by default. If you want to enable RPC, set rpc_endpoint in <system> section.

<system>
  rpc_endpoint 127.0.0.1:24444
</system>

After that, you can access to RPC like below.

$ curl http://127.0.0.1:24444/api/plugins.flushBuffers
{"ok":true}

RPCs

/api/processes.interruptWorkers

Replacement of signal's SIGINT. Stop the daemon.

/api/processes.killWorkers

Replacement of signal's SIGTERM. Stop the daemon.

/api/plugins.flushBuffers

Replacement of signal's SIGUSR1. Flushes buffered messages.

/api/config.reload

Replacement of signal's SIGHUP. reload configuration.
