Suppose you are running a ansible playbook with multiple tasks and want to print execution time of each task, then do the below changes.
Lets see the below sample playbook execution . In this ouput we dont know how much it took for each task execution.
[root@ans_scripts]# ansible-playbook playbook_copyfile_multi.yml -i /etc/ansible/inventory.txt
PLAY [copy files to test servers] ***********************************************************************************************************************************************
TASK [Gathering Facts] **********************************************************************************************************************************************************
ok: [db_server2]
ok: [db_server1]
TASK [Ansible copy files to remote machine] *************************************************************************************************************************************
changed: [db_server1] => (item=test1.log)
changed: [db_server2] => (item=test1.log)
ok: [db_server1] => (item=test2.log)
ok: [db_server2] => (item=test2.log)
PLAY RECAP **********************************************************************************************************************************************************************
db_server1 : ok=2 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
db_server2 : ok=2 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
For enabling the changes, we need to set the callback_whitelist = profile_tasks inside ansible.cfg file.
[root@ansible]# cat /etc/ansible/ansible.cfg |grep callback_whitelist
callback_whitelist = profile_tasks
Now run the same playbook in ansible again.
[root@ans_scripts]# ansible-playbook playbook_copyfile_multi.yml -i /etc/ansible/inventory.txt
PLAY [copy files to test servers] ***********************************************************************************************************************************************
TASK [Gathering Facts] **********************************************************************************************************************************************************
