It would be nice to uninstall the service from a machine no longer being monitored using a nice ansible script.

Running this playbook, I receive an error because of the format of the init script.
Server is CentOS Stream

TASK [service] ***********************************************************************************************************************************************************[WARNING]: The service (site24x7monagent) is actually an init script but the system is managed by systemd
fatal: [puma]: FAILED! => {"changed": false, "msg": "Unable to start service site24x7monagent: Failed to start site24x7monagent.service: Unit site24x7monagent.service not found.\n"}

Thanks for any help you can provide.

 - name: Download 64 bit Site24x7 agent from public URL
   shell: wget -r https://staticdownloads.site24x7.com/server/Site24x7_Linux_64bit.install
   when: ansible_machine == "x86_64"

wget -r make no sense here as you get :

ls -al staticdownloads.site24x7.com/server/Site24x7_Linux_64bit.install

-rw-r--r-- 1 root root 7884199 Aug 5 13:05 staticdownloads.site24x7.com/server/Site24x7_Linux_64bit.install

But on the next command, you change the rights on the file on the current directory :

 - name: Change permission of the downloaded 64 bit install file
   file: path=Site24x7_Linux_64bit.install mode=0755

You can either do a "wget" without "-r" or change the path in the second command.

Also, you playbook doesn't remove the Site24x7_Linux_64bit.install after execution.
