是不是可以这样理解：
- MetricsRecord级别有一些label，也有一些没有自己label的metrics，他们会输出一个metric记录，也就是Line45这一条
- 每个Metric会有自己的一些const和Dynamic label，当有这些label时，一个metric会变成一条单独的metric记录被暴露出来，例如上面的http_flusher_status_code_count * 2，http_flusher_error_count * 3？

指标是有类型的，go这边key是metric_category，value是agent、runner、这些。https://observability.cn/project/loongcollector/internal-metrics-description/#_top
具有单独label的Metric，是不是需要定义为plugin_source级？这块有考虑过吗
