Daggy Sources

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:

            "pingYa": {
                "command": "ping ya.ru",
                "extension": "log"
            }
        }
    }
}
SSH2 type additional parameters
host - remote host ip address or url
connection - map of ssh connection parameters. Includes next parameters
Connection Parameter
Type
Description
Default value
user
string
ssh2 connection login
Current user
passphrase
string
ssh2 connection password. If field is not empty, then will be used password authentication for ssh2 connection. In other case, will be used public key authentication 
​
key
string
path to private key for ssh2 connection
~/.ssh/id_rsa
keyphrase
string
passphrase for private key file
​
port
integer
ssh2 connection port
22
timeout
integer
limit to establish ssh2 connection, in milliseconds
1000
Commands
YAML
JSON
commands:
      pingYa:
        exec: ping ya.ru
        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
Example of using mustache syntax in Daggy Sources
YAML
JSON
aliases:  
    - &my_commands
        pingYa:
            exec: ping ya.ru
            extension: log
        pingGoo:
            exec: ping goo.gl
            extension: log
