Where do I make my configuration settings?

If I have a forwarder, a light forwarder, an indexer, and a search head, where do I need to make my configuration, particular those in props.conf and inputs.conf? Can each setting be done anywhere, or only some places? Does it make a difference where it is set? What happens if the settings are different in each place?

Are the answers to the above questions different for each setting, and if so, is there a listing of these answers anywhere?

Update: I will be offering a bounty on this question. Winning the bounty will require a comprehensive and reasonably easy to read table or chart documenting substantially all inputs.conf and props.conf properties and keys, any significant related ones from other places (such as transforms.conf, outputs.conf). It should indicate where and how the property must be set, where/how it may be set, and what takes precedence in case of conflicts. The properties documented should include:

• source
• sourcetype
• host
• index
• queue
• route / _TCP_ROUTING
• the above for WMI inputs
• time zone / TZ
• time stamp extraction rules
• line breaking rules
• line merging rules
• character set/CHARSET
• extracted fields
• transformed fields
• data masking
• segmentation
