DICE Fault Injection tool, used to generate faults within Virtual Machines and a FCO Cloud Provider. To access the VM level and issue commands the DICE tools use JSCH (http://www.jcraft.com/jsch/) to SSH to the Virtual Machines. When using any argument that requires VM password or SSHKeypath use "-no" for argument not used. Example command: --stressmem 2 512m ubuntu@111.222.333.444 -no c://SSHKEYS/VMkey.key
Supported OS:
- Ubuntu - Tested Ubuntu 14.0, 15.10
- Centos (With set Repo configured & wget installed) - Tested Centos 7
Current User/VM level faults:
- Shutdown random VM (Ignore tagged VM with "noshutdown" in random selection)
- High CPU for VM (Using Stress tool)
- High Memory usage for VM (Using Memtest tool)
- Block VM external access (Using ufw)
- High Bandwidth usage. (Using iperf, requires extrnal iperf server ip to be passed)
- High Disk I/O usage (Using Bonnie ++)
- Stop service running on VM
- Shutdown random VM from whitelist provided by user (Note the whitelist does not check if VM exists or is a in a running state)
- Call YCSB on VM running MongoDB to begin workload test.
- Run JMeter plan
