handshakes

handshakes.try_interval

Default: 100ms

Handshakes are sent to all known addresses at each interval with a linear backoff, waiting try_interval after the 1st attempt, 2 * try_interval after the 2nd, etc, until the handshake is older than timeout.

handshakes.retries

Default: 10

A 100ms interval with the default 10 retries will give a handshake 5.5 seconds to resolve before timing out.

handshakes.trigger_buffer

Default: 64

trigger_buffer is the size of the buffer channel for quickly sending handshakes after receiving the response for lighthouse queries.

handshakes.query_buffer

Default: 1024

query_buffer is the size of the buffer channel for queries to the lighthouses. When it is full, lighthouse queries are dropped and counted in the lighthouse.query.dropped metric. Raise this on hosts that start many tunnels at once. Changing it requires a restart.

  try_interval: 100ms
