Reason: Hardware Failure


Network interface status, 

High packet drop,

low throughput,

excessive latency or jitter


VM

Deployment/Start Failures:

  1. Failed to start*
  2. Failed to boot*

Post-Deployment/Start failures:

  1. Shutdown
  2. Crash
  3. Hang
  4. Panic

Node and Core-mapping


cpu: per-core utilization

memory

Interfaces statistics - sent, recv, drops

Disk Read/Write


If possible, Infrastructure metrics and syslogs from within the VM should be collected.

Deployment/Start failures can be the first step.

Node

A node failure (hardware failure, OS crash, etc)

A) node network connectivity failure

B) nova service failure

D) Failure of other OpenStack services

A) node network connectivity failure

  1. management network
  2. VMs communication network
  3. storage network

B) nova service failure (e.g., process crashed) -- detected and restarted by a local watchdog process

  1. compute
  2. volume
  3. network
  4. scheduler
  5. api.

D) Failure of other OpenStack services -- N/A, assuming redundant/highly available configuration

  1. Glance
  2. Keystone
