内容封装
内容封装绑定了 Graylog2 输入，提取器，流，仪表板和输出配置，可以提供完整的数据源支持。一些内容封装是默认的，可以在这个网站下载，也可以使用 Graylog2 Web 页面导入。 content pack for nginx
新来源页面
新来源页面提供动态分析和不同源代码的导航，可以发送消息到你的 Graylog2 设置。
基于时间的保留清理
你可以选择启用基于时间的保留清理，旧的基于消息计数的策略还是默认的策略，当然，你也可以修改成基于时间的清理
Graylog2 REST API 支持 SSL/TLS
Graylog2 REST API 现在开箱支持 SSL/TLS，提升了系统的安全性。之前的 HTTPS 代理需要部署在 REST API 之前：
•
rest_enable_tls (default: false): Option to activate SSL/TLS for the Graylog2 REST API
rest_tls_cert_file (default: empty): Path to the certificate file. If SSL/TLS is activated but this setting is empty, a temporary self-signed certificate will automatically be created.
rest_tls_key_file (default: empty): Path to the private key file. If SSL/TLS is activated but this setting is empty, a temporary private key will automatically be created.
rest_tls_key_password (default: empty): Optional passphrase to decrypt the private key.
