有大佬用过 zipkin 么?

我们想用 zipkin 收集日志. 自己捕获的错误日志怎么放tags里呢?

{
  traceId: '288e09f4ccc83e536ce7097bb47a470f',
  id: '6ce7097bb47a470f',
  name: 'get',
  kind: 'SERVER',
  timestamp: 1545042239963000,
  duration: 45140,
  localEndpoint:
   Endpoint {
     serviceName: 'node_front_test',
     ipv4: '',
     port: undefined },
  remoteEndpoint: undefined,
  annotations: [],
  tags: { 'http.path': '/test', 'http.status_code': '200' },
  debug: false,
  shared: false
}
