Testing

Why?

• Changes
• Regression
• Impact of outside events (Network, Storage)
• Monitoring (over time)
• Confidence (I have a working environment)
• Recognition of potential problems (in advance)

Challenges

• My specific configuration
• My specific implementation / deployment / infra
• Networking
• Changes outside of my environment ( BGP, Storage, Object Storage, DNS)

Run

# -o    - translate nova/cinder/neutron/glance into openstack client commands
# -C    - full Connectivity check: Every VM pings every other
# -D    - create all VMs with one API call (implies -d -P)
# -n 1  - number of VMs to create
# -B    - measure TCP BW b/w VMs (iperf3)
# -T    - assign tags to resources; use to clean up floating IPs
# -s 10 - sends stats as well once per day (or every SH hours), not just alarms
# -W 45 - sets error wait (VM only): 0-inf seconds or neg value for interactive wait
