Metrics

syncookied supports sending metrics to influxdb over udp. You can use grafana for visualization.

Configuring influxdb

Add this section to influxdb.conf:

[[udp]]
  enabled = true
  bind-address = ":8089"
  database = "syncookied"
  retention-policy = ""
  batch-size = 5000
  batch-pending = 10
  read-buffer = 0
  batch-timeout = "1s"
  precision = ""

Configuring grafana

Add influxdb as a data source
