how to set error log level ?

[matianhe3]

It only shows the "ERR".

    server {
        preread_by_lua_block{
            local errlog = require "ngx.errlog"
            errlog.set_filter_level(ngx.DEBUG)     
            ngx.log(ngx.WARN, "WARN")
          ngx.log(ngx.ERR, "ERR")
      }
 }

The set_filter_level API used in the init_by_lua* init phase.

This ok? also can't work.

http {
    lua_capture_error_log 100k;

    init_by_lua_block {
        local errlog = require "ngx.errlog"
        local status, err = errlog.set_filter_level(ngx.WARN)
        if not status then
            ngx.log(ngx.ERR, err)
            return
        end
        ngx.log(ngx.WARN, "set error filter level: WARN")
        ngx.log(ngx.ERR, "set error filter level: ERR")
    }
}
stream {
 .....
}

you should change the error log level in nginx.conf errlog.set_filter_level set the filter for the ringbuf of the error log which should be get by errlog.get_logs
