Configuration

Simple Data Aggregation Config

simple.yaml
sources:
  localhost:
    type: local
    commands:
      - name: pingYa
        command: ping ya.ru
        extension: log
daggy simple.yaml
23:15:41:005 | AppStatus  | Application     | Start receiver
23:15:41:005 | ConnStatus | localhost       | Server connected
23:15:41:006 | CommStatus | localhost       | pingYa          | Command started

In your working directory daggy were created directory with next template:

{date}-{source_name}

ls
12-06-19_23-15-41-simple  simple.yaml

Output folder contain file with pingYa command output with next template:

{server_name}_{command_name}.{command_extension}

ls 12-06-19_23-15-41-simple/
localhost_pingYa.log

The output file filling at runtime, you can tail content of the file:

tail -f 12-06-19_23-15-41-simple/localhost_pingYa.log

Type CTRL+C for stop commands execution

23:16:25:685 | CommStatus | localhost       | pingYa          | Command was crashed
23:16:25:686 | ConnStatus | localhost       | Server disconnected
23:16:25:686 | AppStatus  | Application     | Stop receiver

Add parallel command

Add new command to our simple config - pingGoo

simple_add_command.yaml
sources:
  localhost:
    type: local
    commands:
      - name: pingYa
        command: ping ya.ru
        extension: log
      - name: pingGoo
        command: ping goo.gl
        extension: log
daggy simple_add_command.yaml 
21:38:02:154 | AppStatus  | Application     | Start receiver
21:38:02:154 | ConnStatus | localhost       | Server connected
21:38:02:154 | CommStatus | localhost       | pingGoo         | Command started
21:38:02:155 | CommStatus | localhost       | pingYa          | Command started
​

pingYa and pingGoo work in parallel, and both commands filling output files localhost_pingGoo.log localhost_pingYa.log at runtime.

You can tail all output files while daggy is working:

tail 14-06-19_21-38-02-simple_add_command/*.log

Add remote server

Now, add remote server 192.168.1.9 with ssh connection with the same commands:

simple_add_remote_server.yaml
sources:
  localhost:
    type: local
    commands:
      - name: pingYa
        command: ping ya.ru
        extension: log
      - name: pingGoo
        command: ping goo.gl
        extension: log
  remotehost:
    type: ssh
    host: 192.168.1.9
    connection:
      login: muxa
      key: /home/muxa/.ssh/id_rsa
    commands:
      - name: pingYa
        command: ping ya.ru
        extension: log
      - name: pingGoo
        command: ping goo.gl
        extension: log
simple_add_remote_server.yaml
daggy simple_add_remote_server.yaml 
22:08:26:093 | AppStatus  | Application     | Start receiver
22:08:26:093 | ConnStatus | localhost       | Server connected
22:08:26:093 | CommStatus | localhost       | pingGoo         | Command started
22:08:26:094 | CommStatus | localhost       | pingYa          | Command started
22:08:26:131 | ConnStatus | remotehost      | Server connected
22:08:26:131 | CommStatus | remotehost      | pingGoo         | Command started
22:08:26:131 | CommStatus | remotehost      | pingYa          | Command started
​

pingYa and pingGoo work in parallel on both servers - localhost and remotehost.

You can tail all output files while daggy is working:

tail -f 14-06-19_22-11-44-simple_add_remote_server/*.log

Grouping commands by name

pingYa and pingGoo are duplicated in last config. Next step, group this commands by name:

simple_group_commands.yaml
aliases:
  - &pingYa
    name: pingYa
    command: ping ya.ru
    extension: log
  - &pingGoo
    name: pingGoo
    command: ping goo.gl
    extension: log
​
sources:
  localhost:
    type: local
    commands:
      - *pingYa
      - *pingGoo
  remotehost:
    type: ssh
    host: 192.168.1.9
    connection:
      login: muxa
      key: /home/muxa/.ssh/id_rsa
    commands:
      - *pingYa
      - *pingGoo
daggy simple_group_commands.yaml 
22:19:18:690 | AppStatus  | Application     | Start receiver
22:19:18:691 | ConnStatus | localhost       | Server connected
22:19:18:691 | CommStatus | localhost       | pingGoo         | Command started
22:19:18:692 | CommStatus | localhost       | pingYa          | Command started
22:19:18:723 | ConnStatus | remotehost      | Server connected
22:19:18:723 | CommStatus | remotehost      | pingGoo         | Command started
22:19:18:723 | CommStatus | remotehost      | pingYa          | Command started
​

Add multiple servers

simple_multiple_servers.yaml
aliases:
  - &pingYa
    name: pingYa
    command: ping ya.ru
    extension: log
​
  - &pingGoo
    name: pingGoo
    command: ping goo.gl
    extension: log
​
  - &my_commands
    - *pingYa
    - *pingGoo
​
  - &ssh_auth
    login: muxa
    key: /home/muxa/.ssh/id_rsa
    
sources:
  localhost:
    type: local
    commands:
      *my_commands
  remotehost:
    host: 192.168.1.9
    type: ssh
    connection:
      *ssh_auth
    commands:
      *my_commands
  remotehost2:
    host: 192.168.1.10
    type: ssh
    connection:
      *ssh_auth
    commands:
      *my_commands
  remotehost3:
    host: 192.168.1.11
    type: ssh
    connection:
      *ssh_auth
    commands:
      *my_commands
daggy simple_multiple_servers.yaml 
23:24:25:118 | AppStatus  | Application     | Start receiver
23:24:25:119 | ConnStatus | localhost       | Server connected
23:24:25:119 | CommStatus | localhost       | pingGoo         | Command started
23:24:25:120 | CommStatus | localhost       | pingYa          | Command started
23:24:25:156 | ConnStatus | remotehost2     | Server connected
23:24:25:156 | CommStatus | remotehost2     | pingGoo         | Command started
23:24:25:156 | CommStatus | remotehost2     | pingYa          | Command started
23:24:25:156 | ConnStatus | remotehost3     | Server connected
23:24:25:156 | CommStatus | remotehost3     | pingGoo         | Command started
23:24:25:156 | CommStatus | remotehost3     | pingYa          | Command started
23:24:25:156 | ConnStatus | remotehost      | Server connected
23:24:25:156 | CommStatus | remotehost      | pingGoo         | Command started
23:24:25:157 | CommStatus | remotehost      | pingYa          | Command started
