## Issue Addressed Closes #1996 ## Proposed Changes Run a second `Logger` via `sloggers` which logs to a file in the background with: - separate `debug-level` for background and terminal logging - the ability to limit log size - rotation through a customizable number of log files - an option to compress old log files (`.gz` format) Add the following new CLI flags: - `--logfile-debug-level`: The debug level of the log files - `--logfile-max-size`: The maximum size of each log file - `--logfile-max-number`: The number of old log files to store - `--logfile-compress`: Whether to compress old log files By default background logging uses the `debug` log level and saves logfiles to: - Beacon Node: `$HOME/.lighthouse/$network/beacon/logs/beacon.log` - Validator Client: `$HOME/.lighthouse/$network/validators/logs/validator.log` Or, when using the `--datadir` flag: `$datadir/beacon/logs/beacon.log` and `$datadir/validators/logs/validator.log` Once rotated, old logs are stored like so: `beacon.log.1`, `beacon.log.2` etc. > Note: `beacon.log.1` is always newer than `beacon.log.2`. ## Additional Info Currently the default value of `--logfile-max-size` is 200 (MB) and `--logfile-max-number` is 5. This means that the maximum storage space that the logs will take up by default is 1.2GB. (200MB x 5 from old log files + <200MB the current logfile being written to) Happy to adjust these default values to whatever people think is appropriate. It's also worth noting that when logging to a file, we lose our custom `slog` formatting. This means the logfile logs look like this: ``` Oct 27 16:02:50.305 INFO Lighthouse started, version: Lighthouse/v2.0.1-8edd9d4+, module: lighthouse:413 Oct 27 16:02:50.305 INFO Configured for network, name: prater, module: lighthouse:414 ```
