i与nginx同一系统上具有NetData设置。我正在监视 stub_status 已经通过NetData进行监视，并且要监视 access.log 日志文件。
i首先复制/usr/lib/netdata/conf.d/python.d/web_log.conf strong text 在目录中>由于这是文档中提到的预期路径。
然后，我启用了文件中的插件/USR/lib/netdata/conf.d/python.d.conf ，但即使那样，我也看不到dashboard中的部分，并在Netdata的错误中看到。记录
即使在启用web_log插件之后，文件/usr/lib/neitdata/conf.d/python.d.conf and /usr/lib/netdata/netdata/conf.d/go。d.conf 可以肯定的是，我可以在error.log中看到其禁用
