stdio adapter enables Istio to output logs and metrics to the local machine. Logs and metrics can be directed to Mixer’s standard output stream, standard error stream, or to any locally reachable file. When outputting to files, you can enable file rotation such that the adapter will automatically manage a set of file backups as data is generated.
