Add peer label to TCP read and write stat queries Closes #5693 ### Tests --- After refactoring, `linkerd viz stat` behaves the same way (I haven't checked gateways or routes). ``` $ linkerd viz stat deploy/web -n emojivoto -o wide NAME MESHED SUCCESS RPS LATENCY_P50 LATENCY_P95 LATENCY_P99 TCP_CONN READ_BYTES/SEC WRITE_BYTES/SEC web 1/1 91.91% 2.3rps 2ms 4ms 5ms 3 185.3B/s 5180.0B/s # same value as before, latency seems to have dropped time="2021-03-22T18:19:44Z" level=debug msg="Query request:\n\tsum(increase(tcp_write_bytes_total{deployment=\"web\", direction=\"inbound\", namespace=\"emojivoto\", peer=\"src\"}[1m])) by (namespace, deployment)" time="2021-03-22T18:19:44Z" level=debug msg="Query request:\n\tsum(increase(tcp_read_bytes_total{deployment=\"web\", direction=\"inbound\", namespace=\"emojivoto\", peer=\"src\"}[1m])) by (namespace, deployment)" # queries show the peer label --- $ linkerd viz stat deploy/web -n emojivoto --from deploy/vote-bot -o wide NAME MESHED SUCCESS RPS LATENCY_P50 LATENCY_P95 LATENCY_P99 TCP_CONN READ_BYTES/SEC WRITE_BYTES/SEC web 1/1 93.16% 1.9rps 3ms 4ms 4ms 1 4503.4B/s 153.1B/s # stats same as before except for latency which seems to have dropped a bit time="2021-03-22T18:22:10Z" level=debug msg="Query request:\n\tsum(increase(tcp_write_bytes_total{deployment=\"vote-bot\", direction=\"outbound\", dst_deployment=\"web\", dst_namespace=\"emojivoto\", namespace=\"emojivoto\", peer=\"dst\"}[1m])) by (dst_namespace, dst_deployment)" time="2021-03-22T18:22:10Z" level=debug msg="Query request:\n\tsum(increase(tcp_read_bytes_total{deployment=\"vote-bot\", direction=\"outbound\", dst_deployment=\"web\", dst_namespace=\"emojivoto\", namespace=\"emojivoto\", peer=\"dst\"}[1m])) by (dst_namespace, dst_deployment)" # queries show the right label ``` Signed-off-by: mateiidavid <matei.david.35@gmail.com> |
