Function Documentation

void foxglove::setLogLevel(LogLevel level)

Initialize SDK logging with the given severity level.

The SDK logs informational messages to stderr. Any messages below the given level are not logged. Note that this does not affect logging of messages to MCAP or Foxglove.

This function should be called before other Foxglove initialization to capture output from all components.

As long as you initialize one logging sink (WebSocket server or MCAP), log level may instead be configured via a FOXGLOVE_LOG_LEVEL environment variable, with one of the values “debug”, “info”, “warn”, “error”, or “off”. Default is “info”.

Additionally, you may control whether style characters such as colors are included in log output via the FOXGLOVE_LOG_STYLE environment variable. Valid values are “never”, “always”, and “auto”. “auto” will attempt to print styles where supported; this is the default.

If this method is not called, and neither of the environment variables are set, this logging is disabled.

Note

This is thread-safe, but only the first call to this function will have an effect.

Parameters:

level – The severity level for stderr logging from the SDK.
