AWS healthd 守护进程警告 - nginx 日志文件不存在

Question

我已经使用 elasticbeanstalk 和 nginx 部署了一个 nodejs 应用程序。

当我检查日志目录 /var/log/nginx/

1. healthd 文件夹存在并且
2. nginx 正在创建 /var/log/nginx/healthd/application.log.2019-10-04-13

但是在 /var/log/healthd 文件夹中有一个 daemon.log 文件，我每 5 秒就会在其中收到以下错误。

    # Logfile created on 2019-10-04 13:46:46 +0000 by logger.rb/47272

那么如何让守护进程读取 nginx healthd 日志文件呢？

Answer 1

我也遇到了这个神秘的错误。尤其神秘的是，如果你检查一下，你会发现 /var/log/nginx/healthd/application.log.XXX 确实存在！

我发现在某些情况下，healthd 需要额外的配置来解决此错误。

看看这个： https: //docs.aws.amazon.com/elasticbeanstalk/latest/dg/health-enhanced-serverlogs.html

一旦我为 healthd 提供了正确的日志形成配置，这个错误就消失了。
