* Revamp metrics processing in MetricUtils
- Try to improve documentation of functions
- Remove nested data from processed metrics - they were often duplicated data
- Split out timeseries processing from rollup processing
- Remove the 'rollup' level of nesting
- Limit the number of timeseries we fetch on the deployments page
This PR adds a configurable timeout duration after which in-flight telemetry reports are dropped, cancelling the corresponding RPC request to the control plane.
I've also made the `Timeout` implementation used in `TimeoutConnect` generic, and reused it in multiple places, including the timeout for in-flight reports.

Fix various loose ends in the web app:
* Add Tooltip to status dots explaining color meaning
* Adjust formatting of RPS numbers
* Pass in current success rate to the HealthPane
* Fix page header styling caused by content being in wrong div
* Align the metric value for inbound SR in Health Pane
* Status Dot tweaks
* Improve rendering of status dots when there are a lot of them
* Add support for path stats in cli and web api
The cli stat command supports grouping by pod and deployment. With this
change, it will also support grouping by path, in order to facilitate a
summary stats per individual endpoint.
* Right-align numeric columns in stat output
Problem:
Simulate proxy would seemingly hang when used.
In simulate-proxy we were using rand.Uint32() to generate Count. This is way too big (in telemetry/server.go we call latencyStat.observe() Count times, so this loop was taking fovever).
Solution:
Use a count of 1 (as the surrounding loop will generate count requests)
Validation:
Script now works without hanging.
* Proxy: Improve error reporting for invalid environment variables
Previously when an environment variable had an invalid value the
process would exit with an error that did not mention which
environment variable is invalid.
Start fixing this by routing environment variable parsing through
functions that always know the name of the environment variable when
they report errors.
I validated this change manually.
* Proxy: Improve configuration URL parsing
Previously there was a bit of duplicated logic between parsing `Addr`
and `HostAndPort` values.
Factor out the common logic. In the process, improve the error
reporting in the cases where parsing fails.
We’ve built Conduit from the ground up to be the fastest, lightest,
simplest, and most secure service mesh in the world. It features an
incredibly fast and safe data plane written in Rust, a simple yet
powerful control plane written in Go, and a design that’s focused on
performance, security, and usability. Most importantly, Conduit
incorporates the many lessons we’ve learned from over 18 months of
production service mesh experience with Linkerd.
This repository contains a few tightly-related components:
- `proxy` -- an HTTP/2 proxy written in Rust;
- `controller` -- a control plane written in Go with gRPC;
- `web` -- a UI written in React, served by Go.
