Redis proxy¶

Redis architecture overview
v2 API reference
This filter should be configured with the name envoy.filters.network.redis_proxy.

Statistics¶

Every configured Redis proxy filter has statistics rooted at redis.<stat_prefix>. with the following statistics:

Name	Type	Description
downstream_cx_active	Gauge	Total active connections
downstream_cx_protocol_error	Counter	Total protocol errors
downstream_cx_rx_bytes_buffered	Gauge	Total received bytes currently buffered
downstream_cx_rx_bytes_total	Counter	Total bytes received
downstream_cx_total	Counter	Total connections
downstream_cx_tx_bytes_buffered	Gauge	Total sent bytes currently buffered
downstream_cx_tx_bytes_total	Counter	Total bytes sent
downstream_cx_drain_close	Counter	Number of connections closed due to draining
downstream_rq_active	Gauge	Total active requests
downstream_rq_total	Counter	Total requests

Splitter statistics¶

The Redis filter will gather statistics for the command splitter in the redis.<stat_prefix>.splitter. with the following statistics:

Name	Type	Description
invalid_request	Counter	Number of requests with an incorrect number of arguments
unsupported_command	Counter	Number of commands issued which are not recognized by the command splitter

Per command statistics¶

The Redis filter will gather statistics for commands in the redis.<stat_prefix>.command.<command>. namespace. By default latency stats are in milliseconds and can be changed to microseconds by setting the configuration parameter latency_in_micros to true.

Name	Type	Description
total	Counter	Number of commands
success	Counter	Number of commands that were successful
error	Counter	Number of commands that returned a partial or complete error response
latency	Histogram	Command execution time in milliseconds

Runtime¶

The Redis proxy filter supports the following runtime settings:

redis.drain_close_enabled: % of connections that will be drain closed if the server is draining and would otherwise attempt a drain close. Defaults to 100.
