Whenever we have an issue, currently there is no way to pull out additional information post-mortem. We have to re-create the issue. This is particularly time intense to re-create, even with the existence of zombienet.
paritytech/polkadot#2376 solves this, but only after the alarms go of, at which point most of the information that lead to the state is already gone.
In the embedded space there is something called compressed logging, where a static lookup table is generated at compile time to only emit a well defined wire format that is then expanded on the logging ingestor. Popular example being https://crates.io/crates/defmt
Now this is far from perfect, since we still want' directly readable metrics. The solution might be a hybrid approach, where a (assuming
defmt) we could extendgum(our existing wrapper) to always print todefmt, at all levels, but only print the desired logging level.The text was updated successfully, but these errors were encountered:
