Corn Job to stop running all lab's Nodes

Post by prasath1017 » Fri Jul 12, 2019 8:15 am

I have provisioned community edition and provided multiple user PODs. This is killing my server resources when the lab is left running and idle.
Could you pleaes help me with a simple script on eve-ng community version using to stop all idle nodes using "script / Cron tab" to kill all idle nodes.

Hi,
I am running crontab everyday to reboot the VM for now.

0 0 * * * root /sbin/shutdown -r now # reboot every day at 00:00 am

Will explore to identify how to kill "dynamips", "qemu" and other nodes. If anyone has tried it, please share your thoughts :)

I have tested the below and it works for my requirement.
Add the below cron job to kill the process with the pattern of any qemu, iol and dynamips.

edit the /etc/crontab
0 3 * * * root pkill qemu
0 3 * * * root pkill iol
0 3 * * * root pkill dynamips

The above will stop all nodes from any lab at 3am everyday.
