为什么logstash-forwarder在每个伐木机请求中发送的事件不超过100个？

Question

我已经看到，是flush_size控制着lumberjack(logstash-forwarder)中的每个请求发送的事件，但我已经将其设置为150，如下所示

config :flush_size, :validate => :number, :default => 150

文件：/opt/logstash/lib/logstash/outputs/elasticsearch_http.rb

但是我仍然没有看到lumberjack每个请求发送超过100个事件。

在此之后，我重新启动了logstash和logstash-forwarder，但它仍然不工作。

编辑init脚本并更改-spool-size的值：

grep DAEMON_ARGS /etc/init.d/logstash-forwarder

DAEMON_ARGS="-config /etc/logstash-forwarder -spool-size 100 -log-to-syslog“

/etc/init.d/logstash-forwarder重新启动
