TCP proxy


The TCP proxy filter emits both its own downstream statistics as well as many of the cluster upstream statistics where applicable. The downstream statistics are rooted at tcp.<stat_prefix>. with the following statistics:

Name Type Description
downstream_cx_total Counter Total number of connections handled by the filter.
downstream_cx_no_route Counter Number of connections for which no matching route was found.
downstream_cx_tx_bytes_total Counter Total bytes written to the downstream connection.
downstream_cx_tx_bytes_buffered Gauge Total bytes currently buffered to the downstream connection.
downstream_flow_control_paused_reading_total Counter Total number of times flow control paused reading from downstream.
downstream_flow_control_resumed_reading_total Counter Total number of times flow control resumed reading from downstream.
