我们有一个logstash管道,其中许多logstash-forwarders将日志转发到单个logstash实例。很多时候我们发现logstash会挂起以下错误: -
[2016-07-22 03:01:12.619] WARN -- Concurrent::Condition: [DEPRECATED] Will be replaced with Synchronization::Object in v1.0.
called on: /opt/logstash-1.5.3/vendor/bundle/jruby/1.9/gems/logstash-input-lumberjack-1.0.2/lib/logstash/sized_queue_timeout.rb:16:in `initialize'
Exception in thread ">output" java.lang.UnsupportedOperationException

我们的logstash配置如下所示: -
input {
lumberjack {
port => 6782
codec => json {}
ssl_certificate => "/opt/logstash-1.5.3/cert/logstash-forwarder.crt"
ssl_key => "/opt/logstash-1.5.3/cert/logstash-forwarder.key"
type => "lumberjack"
}
}
filter {
if [env] != "prod" and [env] != "common" {
drop {}
}
if [message] =~ /^\s*$/ {
drop { }
}
}
output {
if "_jsonparsefailure" in [tags] {
file {
path => "/var/log/shop/parse_error/%{env}/%{app}/%{app}_%{host}_%{+YYYY-MM-dd}.log"
}
} else {
kafka {
broker_list => ["kafka:9092"]
topic_id => "logstash_logs2"
}
}
}
重新启动logstash后,它再次开始工作。有人可以让我知道为什么会出现这个问题,我们如何在不重新启动logstash的情况下解决这个问题?
