The CORE_COLLECTOR variable might contain sensitive information (e.g., passwords, API keys) if custom configurations are used. Printing it as debug information could expose these secrets. Consider sanitizing the output or using a more secure way to log this information.

For example, you could log a hash of the sensitive parts, or redact them entirely.

ddebug "Core Collector: $CORE_COLLECTOR"
ddebug "Core Collector: $(echo "$CORE_COLLECTOR" | sed 's/password=\S*//g')" # Redact sensitive information
