我这里关于prometheus-nginxlog-exporter有点问题
问题遇到的现象和发生背景
背景：有一个场景，服务器运行Prometheus，另一台机子是跑nginx的，但某些特殊原因，另一台机子只能发送nginx的log文件到服务器上，所以找到了prometheus-nginxlog-exporter，想利用这个exporter来解析log文件然后发送给Prometheus。
运行结果及报错内容
我按照github上的文档进行了配置，运行exporter，结果如下：
[root@localhost sbin]# ./prometheus-nginxlog-exporter -config-file /etc/prometheus-nginxlog-exporter.hcl
loading configuration file /etc/prometheus-nginxlog-exporter.hcl
No globs for /usr/local/nginx/logs/access.log

然后网页端输出结果如下：
