Metrics

vey-gateway currently exports metrics through StatsD. See stat for configuration details.

Common Tags

The following tags are shared by all metrics:

• daemon_group

  This tag matches the daemon group set in the configuration file or on the command line.

• stat_id

  A host-local unique ID used for deduplication. StatsD should drop this tag so metrics with the same remaining tags can be aggregated.

• transport

  The transport-layer protocol. Values are:

  • tcp

  • udp

• quantile

  The quantile label for histogram metrics.

  The following values are always present:

  • min

  • max

  • mean

  Additional quantiles can be configured with histogram metrics. If not set, the following values are added by default:

  • 0.50

  • 0.80

  • 0.90

  • 0.95

  • 0.99
