An automated KVM virtual machine CPU, Disk (LVM) and Network throughput throttle script

Scope: - The script should monitor CPU on KVM guests in a KVM hypervisor and throttle CPU on guests which are abusing/using CPU for X amount of time - The script should monitor LVM DISK I/O Throughput on KVM guests in a KVM hypervisor and throttle DISK Read/Write on guests which are abusing/using a high amount of Disk for X amount of time - The script should monitor Network Upload Throughput on KVM guests in a KVM hypervisor and throttle Network Upload on guests which are doing more than X MBPS in a given time period - The script also should un-throttle the throttled metric back to normal after x hours This script will run on each Hypervisor, monitoring/gathering the relevant data to calculate the above items. Required Webhooks The script should send a Webhook event to a specified endpoint for the following events -- After Throttled (data: KVM Guest name and reason of throttle) -- After Un-throttled (data: KVM Guest name) Required API The script should also support these API methods -- Throttle a guest manually (accepted data: Guest name and throttle type (Disk, CPU, Network)) -- Un-throttle a guest manually (accepted data: Guest name) Variables The following should be variables retrieved via an endpoint to base the throttling/un-throttling conditions - CPU % used for throttling condition - Disk read/write throughput used for throttling condition - Network upload throughput used for throttling condition - Time to watch before throttling - Number of hours before un-throttling Script Technical Spec - The script should be lightweight - Throttling method should be lightweight and straightforward - Programming language: any (PHP, Bash, Perl preferred) - The script should work on all Linux CentOS 7 environments without issues
