Logstash
嘗試發送到 slack webhook 時，Logstash 輸出-http 外掛錯誤 500
我正在執行一個帶有 ELK 堆棧的 docker 容器。一切都很好，很好。我想使用https://www.elastic.co/guide/en/logstash/current/plugins-outputs-http.html外掛。
我安裝外掛它：
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logstash配置文件：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\"}" } } }我還嘗試更改 http 中的格式：
... format => "message" ...該配置也經過測試並且有效：
root@elk:/# /opt/logstash/bin/logstash --configtest -f /etc/logstash/conf.d/logstash.conf Configuration OK兩者都導致它不起作用。我仔細檢查以確保 webhook 正在使用測試（來自 logstash docker 容器）：
curl -H "Content-Type: application/json" -X POST -d '{"text":"testing"}' https://hooks.slack.com/services/<MY_ID>我知道標籤被正確應用，在 Kibana 中檢查。此外，if 子句也在工作，因為我
elasticsearch在其中進行了測試，它確實只將帶有添加error標籤的日誌發送到 elasticsearch。最後是來自以下的神聖錯誤消息

response_code => 500內部錯誤。format => "json"和都出現同樣的錯誤format => "message"。我猜這與我的配置有關（顯然）。
顯然logstash 有雙引號問題，我很驚訝（也很失望）。這是工作程式碼：
if "error" in [tags] { http { http_method => "post" url => "https://hooks.slack.com/services/<MY_ID>" format => "message" message => '{"text":"hello"}' } }
