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 |
