error.log has log level, accesslog doesn't. Should I set the default log level for accesslog?

Which logs are you gathering from accesslog? The log output should include the level, isn't it?

nginx output accesslog and errorlog in two files, I collect both of them. error log has log level but access log doesn't.

log_format myformat '$remote_addr - $remote_user [$time_local] '
                    '"$request" $status $body_bytes_sent '
                    '"$http_referer" "$http_user_agent" '
                    '"$http_x_forwarded_for"';

access_log /path/to/access.log myformat;

I think we should extract $status from a defined format. And tag the error level and http.status_code. Also, add http.status_code into searchableLogsTags.

@weixiang1862 Generally, this should be good. I will wait for others' review. And would you be able to add Nginx monitoring

And I believe another blog to introduce your new thing would be cool. This should be more powerful than you introduced in the last one. WDYT?

The time is totally flexible, and up to your reality.
