How to setup data sources for Daggy
Supported formats
Daggy supports yaml and json formats. In yaml repeated nodes can be grouped by yaml standard.
Data sources template
YAML
JSON
sources:
    host1:
        #....
    host2:
        #....
    #....
    hostN:
        #....
    
{
    "sources": {
        "host1" : {
        },
        "host2" : {
        },
        "hostN" : {
        }
    }
}
Each config conatins map of hosts. Host (data source) parameters is next:

Commands
YAML
JSON
commands:
      pingYa:

        extension: log
        restart: false
"commands": {
            "pingYa": {
                "command": "ping ya.ru",
                "extension": "log"
            }
        }
Each command must contain:
name - unique within host command identifier, using in command output file name template.
exec - shell script
extension - extension for command output file
restart - restart command if it finished
Using environment and other variables in Data Aggregation Sources
Mustache syntax
YAML/JSON Data Aggregation Sources are support mustache syntax:
env_* - template for environment variable, where * is environment variable name.
output_folder - output folder path
