我正在运行一个ELK栈的docker容器。 各种各样的花花公子和罚款。 我想使用https://www.elastic.co/guide/en/logstash/current/plugins-outputs-http.html插件。
我安装它的插件：
root@elk:/# /opt/logstash/bin/plugin install logstash-output-http Validating logstash-output-http Installing logstash-output-http Installation successful /etc/logstash/conf.d/logstash.conf主要的logstashconfiguration文件：
input { beats { port => 5044 type => "logs" } } filter { grok { match => { "message" => "\"name\":\"Error\""} add_tag => ["error"] } } output { elasticsearch { hosts => "localhost:9200" sniffing => true manage_template => false index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}" document_type => "%{[@metadata][type]}" } if "error" in [tags] { http { http_method => "post" url => "https://hooks.slack.com/services/<MY_ID>" format => "json" content_type => "application/json" message => "{\"text\": \"dis is workinz\"}" } } }
我也试着改变http：
... format => "message" ...
configuration也被testing并且是有效的：
root@elk:/# /opt/logstash/bin/logstash --configtest -f /etc/logstash/conf.d/logstash.conf Configuration OK
两者都导致它无法正常工作。 我再次检查以确保webhook正在testing（从logstash泊坞窗容器）：
curl -H "Content-Type: application/json" -X POST -d '{"text":"testing"}' https://hooks.slack.com/services/<MY_ID>
我知道标签正在正确应用，在Kibana检查。 此外，if子句也在工作，因为我在testing中join了elasticsearch ，而且确实只是将带有添加的error标签的日志发送到elasticsearch。
最后来自/var/log/logstash/logstah.log的神圣错误消息：

正如你可以看到它声明response_code => 500内部错误。 我得到同样的错误format => "json"和format => "message" 。
我猜这与我的configuration有关（显然）。
显然logstash有双引号的问题，我很惊讶（和失望）。 这是工作代码：
if "error" in [tags] { http { http_method => "post" url => "https://hooks.slack.com/services/<MY_ID>" format => "message" message => '{"text":"hello"}' } }
