servers ([]FluentdServer, required) 🔗︎

Server definitions at least one is required Server

Default: -

require_ack_response (bool, optional) 🔗︎

Change the protocol to at-least-once. The plugin waits the ack from destination’s in_forward plugin.

Default: -

ack_response_timeout (int, optional) 🔗︎

This option is used when require_ack_response is true. This default value is based on popular tcp_syn_retries.

Default: 190

send_timeout (int, optional) 🔗︎

The timeout time when sending event logs.

Default: 60

connect_timeout (int, optional) 🔗︎

The timeout time for socket connect. When the connection timed out during establishment, Errno::ETIMEDOUT is raised.

Default: -

recover_wait (int, optional) 🔗︎

The wait time before accepting a server fault recovery.

Default: 10

heartbeat_type (string, optional) 🔗︎

The transport protocol to use for heartbeats. Set “none” to disable heartbeat. [transport, tcp, udp, none]

Default: -

heartbeat_interval (int, optional) 🔗︎

The interval of the heartbeat packer.

Default: 1

phi_failure_detector (bool, optional) 🔗︎

Use the “Phi accrual failure detector” to detect server failure.

Default: true

phi_threshold (int, optional) 🔗︎

The threshold parameter used to detect server faults. phi_threshold is deeply related to heartbeat_interval. If you are using longer heartbeat_interval, please use the larger phi_threshold. Otherwise you will see frequent detachments of destination servers. The default value 16 is tuned for heartbeat_interval 1s.

Default: 16

hard_timeout (int, optional) 🔗︎

The hard timeout used to detect server failure. The default value is equal to the send_timeout parameter.

Default: 60

Set TTL to expire DNS cache in seconds. Set 0 not to use DNS Cache. (defult: 0)

Default: -

dns_round_robin (bool, optional) 🔗︎

Enable client-side DNS round robin. Uniform randomly pick an IP address to send data when a hostname has several IP addresses. heartbeat_type udp is not available with dns_round_robin true. Use heartbeat_type tcp or heartbeat_type none.

Default: -

ignore_network_errors_at_startup (bool, optional) 🔗︎

Ignore DNS resolution and errors at startup time.

Default: -
