TCP proxy

Statistics

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
