我已经使用 Stackdriver Logging 很长时间了，现在我也想利用错误报告。如果可能（出于各种原因），我宁愿使用 Python 的日志记录机制并从日志文件中刮除异常，而不是使用 error_reporting 库。话虽如此，文档非常混乱。例如文档说： https ://cloud.google.com/error-reporting/docs/setup/compute-engine#log_exceptions

首先，安装 fluent-logger-python 库：

sudo pip install google-cloud-error-reporting --upgrade

这让我相信 google-cloud-error-reporting 是 fluent-logger-python 的一个分支或与之相关，但是，当我初始化 google-cloud-error-reporting 它直接调用 GCE 元数据服务器而不是连接到当地流利的。这两个不相关的软件包或者文档是否错误或具有误导性？如果我将 JSON 格式的异常发送到 fluentd 或 fluentd 监控的日志文件，错误报告会理解它们吗？

感谢您的任何澄清

文档是错误的。
TL;DR 您必须输出类似于https://cloud.google.com/error-reporting/docs/formatting-error-messages的内容

这是我的解决方案：

#Parse raw log entries to expose severity field so that
#StackDriver log viewer can properly categorize (and so we can filter)
<source>
  @type tail
  path /var/log/conductor
  pos_file /var/log/td-agent/conductor.pos
  format multiline
  format_firstline /\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}/
  format1 /^(?<message>(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}),\d*\s*[a-zA-Z_]*\s*(?<severity>[A-Z]*).*)/
  read_from_head true
  multiline_flush_interval 3s
  tag conductor.app
</source>

#Add hostname field
<filter conductor.app>
  @type record_transformer
  <record>
    hostname ${hostname}
  </record>
</filter>

#Filter and tag log entries of severity ERROR or CRITICAL
<match conductor.app>
  @type rewrite_tag_filter
  rewriterule1 severity ERROR|CRITICAL conductor.err
  rewriterule2 severity .+ conductor.info
</match>

#Process entries with tracebacks differently than those without
<match conductor.err>
  @type rewrite_tag_filter
  rewriterule1 message .*Traceback conductor.err.traceback
  rewriterule2 message .+ conductor.err.message
</match>

#Parse out the traceback
<match conductor.err.traceback>
  @type parser
  key_name message
  format multiline
  format1 /^(?<message>(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}),\d*\s*(?<log>[a-zA-Z_]*)\s*(?<severity>[A-Z]*).*(?
<traceback>Traceback .*))/
  tag conductor.err.traceback.report
</match>

#Format traceback reports
<filter conductor.err.traceback.report>
  @type record_transformer
  <record>
      serviceContext {
        "service": "${record[\"log\"]}"
      }
      message ${record["traceback"]}
  </record>
  remove_keys traceback
</filter>

#Process errors that don't have tracebacks
<match conductor.err.message>
  @type parser
  key_name message
  format multiline
  format1 /^(?<message>(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}),\d*\s*(?<log>[a-zA-Z_]*)\s*(?<severity>[A-Z]*):\s*(?<report>.*))/
  tag conductor.err.message.report
</match>

#For errors without tracebacks we have to stub out some fields that
#error reporting requires, but we don't have
<filter conductor.err.message.report>
  @type record_transformer
  <record>
      serviceContext {
        "service": "${record[\"log\"]}"
      }
      message ${record["report"]}
      reportLocation {
        "filePath": "None",
        "lineNumber": 0,
        "functionName": "None"
      }
  </record>
</filter>

#Send to StackDriver logging!
<match conductor.**>
  @type google_cloud
  buffer_chunk_limit 2M
  flush_interval 5s
  max_retry_wait 300
  disable_retry_limit
  num_threads 8
</match>

您可以在此处按照教程进行操作：https ://cloud.google.com/run/docs/logging#writing_structured_logs

您可以使用 python 创建一个 dict 并将其记录到 Stackdriver - 它将与跟踪相关联。它应该看起来像这样（来自教程）：

# Build structured log messages as an object.
global_log_fields = {}

# Add log correlation to nest all log messages
# beneath request log in Log Viewer.
trace_header = request.headers.get('X-Cloud-Trace-Context')

if trace_header and PROJECT:
    trace = trace_header.split('/')
    global_log_fields['logging.googleapis.com/trace'] = (
        f"projects/{PROJECT}/traces/{trace[0]}")

# Complete a structured log entry.
entry = dict(severity='NOTICE',
             message='This is the default display field.',
             # Log viewer accesses 'component' as jsonPayload.component'.
             component='arbitrary-property',
             **global_log_fields)

print(json.dumps(entry))
