Get information about remote hosts using Ansible

Get information about remote hosts using Ansible setup command

Below command gives all the information of client hosts which includes memory, server architecture, IP adresses etc.

[root@ansible mywork]# ansible all -i hosts -m setup


If you need just memory information of remote node then for the above command need to add filter as shown below

[root@ansible mywork]# ansible all -i hosts -m setup -a "filter=ansible_*_mb"
node01 | SUCCESS => {
    "ansible_facts": {
        "ansible_memfree_mb": 873,
        "ansible_memory_mb": {
            "nocache": {
                "free": 919,
                "used": 77
            },
            "real": {
                "free": 873,
                "total": 996,
                "used": 123
            },
            "swap": {
                "cached": 0,
                "free": 1535,
                "total": 1535,
                "used": 0
            }
        },
        "ansible_memtotal_mb": 996,
        "ansible_swapfree_mb": 1535,
        "ansible_swaptotal_mb": 1535
    },
    "changed": false

Using ansible ping module check connectivity between two nodes

Using ansible ping module check connectivity between two nodes Once server and client machine is configured with SSH passwordless authentication and  ansible installed in server, we will verify if ansible can connect from server to client. If you have not configured refer page Login to server node and create a directory to save all the work done in one location Eg:mywork [root@ansible ~]# mkdir mywork [root@ansible ~]# cd mywork/ Create new file called "hosts" under "mywork" and add your client host name in the file as shown below. [root@ansible mywork]# cat hosts [mynodes] node01 Now is the time to check if ansible from server machine able to communicate to client node01 To check this we will use ansible module called ping. Run command as shown below. [root@ansible mywork]# ansible all -i hosts -u root -m ping node01 | SUCCESS => {     "changed": false,     "ping": "pong" }
