This is to explain how we can write a small playbook to collect uptime of all servers in our environment.
We can use our own server list or group name as referred in Ansible Inventory. Here I used "infra_redhat" which is already defined in Ansible Inventory.
We can also mention the mail Id to which we need to recieve uptime report.
With this playbook, we are running in a jumphost or some admin server from where, all servers are connected.
We are just collecting outout of "uptime" command and saving a small CSV file.
- name: Checking the server uptime
hosts: infra_redhat
gather_facts: no
tasks:
- name: Create the server uptime report
copy:
content: Server Name, Uptime
dest: /var/tmp/serveruptime.csv
delegate_to: localhost
- name: getting the uptime of mysql
shell: uptime
register: output_uptime
changed_when: "output_uptime.rc != 0"
- name:
set_fact:
UPTIME: "{{ output_uptime.stdout | replace('\t','') }}"
- name: display the message
lineinfile:
line: "{{ inventory_hostname }},{{ UPTIME }}"
insertafter: EOF
path: /var/tmp/serveruptime.csv
delegate_to: localhost
- name: Mail uptime report
hosts: localhost
tasks:
- name: server uptime mail
mail:
subject: Server uptime report
body: Hi, Please find attached server uptime report
to:
- root@localhost
attach:
- /var/tmp/serveruptime.csv
Once this is run, we get good output in CSV format like follows,
$ cat /var/tmp/serveruptime.csv
Server Name, Uptime
server1, 04:00:20 up 38 days, 13:12, 1 user, load average: 0.42, 1.38, 0.87
server2, 04:00:18 up 38 days, 14:33, 1 user, load average: 0.00, 0.07, 0.13
server3, 04:00:20 up 39 days, 13:14, 1 user, load average: 0.04, 0.74, 0.79
