Logging

Nimi streams service logs to stdout/stderr and can also write per-service log files when settings.logging.enable is set.

File layout

When logging is enabled, Nimi creates a run-specific directory under settings.logging.logsDir and writes one file per service:

• logs-{n}/service-a.txt
• logs-{n}/service-b.txt

Where n is the successive iteration ran using the same logging directory

Each file receives line-oriented output from the service. Both stdout and stderr are appended to the same file, so the contents reflect the combined stream.

Configuration

settings.logging = {
  enable = true;
  logsDir = "my_logs";
};

Notes

• Log files are created at runtime; they do not exist in the Nix store.
• Disabling logging still streams logs to stdout/stderr, but no files are created.
