tokio-console roadmap

console-roadmap.md

/!\ this is just a sketch to write down the roadmap items, should be made nice before publishing!

• more warnings --- get feedback from people, find what common bugs or gotchas we can detect!
  • e.g. tokio-rs/console#203
• richer warnings system
  • it would be good to have web docs explaining different warnings in detail, how they can be fixed, etc, like clippy's
  • toggle warnings on and off, configure thresholds for warnings
  • see tokio-rs/console#181
  • see tokio-rs/console#148
  • non-interactive mode for recording a log of warnings, e.g. in tests: tokio-rs/console#147
• runtime improvements!
  • identify multiple separate tokio runtimes and show which runtime a task is on, for apps using multiple rts
  • integration with runtime stats (and also see above) for global rt stats
  • get non-tokio runtimes to add console support (this is their problem)
  • see tokio-rs/console#130
• record/replay
  • the bones are there for this but it needs ui work
  • see tokio-rs/console#70
  • see tokio-rs/console#96
• more visualizations!
  • tree mode --- show which tasks spawned which other tasks, etc
  • resource tree mode tokio-rs/console#155
  • timeline view: tokio-rs/console#129
• general app stats/monitoring (e.g. cpu/mem/etc)
  • see tokio-rs/console#69
  • see tokio-rs/console#161
  • top-level metrics tokio-rs/console#14
• interactive filtering/querying
  • see tokio-rs/console#73
  • see tokio-rs/console#131
• richer support for errors
  • capture panics? tokio-rs/console#179
  • record task errors? tokio-rs/console#172
  • more structured/richer error fields tokio-rs/console#34
• richer tracing support
  • stream a log of all events in a given task from the UI
  • capture user span contexts for tasks better...we don't currently do this

Third-party roadmap!

• people can write other UI layers outside of the console CLI
  • there's already a POC grafana thingy --- find a link to this?
  • web UI mode would be nice
• considering putting the console CLI's data model and client code in a crate that can be used for building other UI layers?
• other runtimes (rayon!) add instrumentation?
• non-interactive consumers that export to other tools (pprof? etc)
