logging - 显示 Graphite 无效线

Question

我在我的 Graphite 日志中看到很多这样的行:

01/10/2014 21:07:12 :: [listener] invalid line received from client HOST:PORT, ignoring

如果我能看到无效行，那将大有帮助。一些文档和教程建议 Graphite 会在无效警告后直接打印违规行，但对我来说它不会。如何启用此属性？

谢谢。

所以我尝试解决这个问题是一个彻底的黑客攻击，但它对我有用。

步骤

• 编辑 protocol.py(/opt/graphite/lib/carbon/protocols.py 第 75 行并添加额外的日志行

前:

 class MetricLineReceiver(MetricReceiver, LineOnlyReceiver):
    delimiter = '\n'

  def lineReceived(self, line):
    try:
      metric, value, timestamp = line.strip().split()
      datapoint = (float(timestamp), float(value))
    except:
      log.listener('invalid line received from client %s, ignoring' % self.peerName )
      return

    self.metricReceived(metric, datapoint)

后:

 class MetricLineReceiver(MetricReceiver, LineOnlyReceiver):
    delimiter = '\n'

  def lineReceived(self, line):
    try:
      metric, value, timestamp = line.strip().split()
      datapoint = (float(timestamp), float(value))
    except:
      log.listener('invalid line received from client %s, ignoring' % self.peerName )
      log.listener('invalid line - [ %s ]' % line)
      return

    self.metricReceived(metric, datapoint)

• 在 Debug模式下重启守护进程

  /usr/bin/python/opt/graphite/bin/carbon-cache.py --pid/opt/graphite/storage/carbon-cache-a.pid --debug 开始

• 找到问题指标并修复
• 还原对 protocol.py 的更改
• 作为守护进程重启 carbon-cache

通过这样做，我能够准确地看到是哪个指标让我感到悲伤并加以解决。

希望对您有所帮助!
