Metrics

Metrics are currently exported through StatsD. See stat for configuration details.

Common Tags

The following are the common tags used by all metrics:

  • daemon_group

    Same daemon-group value configured in the config file or command-line arguments.

  • stat_id

    A machine-local unique stat_id used for deduplication. It should be dropped by the StatsD aggregation pipeline so that metrics with the same remaining tags can be aggregated.

  • quantile

    Quantile value for histogram statistics.

    The following values are always present:

    • min

    • max

    • mean

    Values can be added by histogram metrics config. If not set, the following values are added by default:

    • 0.50

    • 0.80

    • 0.90

    • 0.95

    • 0.99
