Inspector.inspect_cpu_util(instance, duration=None)[source]

Inspect the CPU Utilization (%) for an instance.

Parameters:
  • instance – the target instance
  • duration – the last ‘n’ seconds, over which the value should be inspected
Returns:

the percentage of CPU utilization

Inspector.inspect_cpus(instance)[source]

Inspect the CPU statistics for an instance.

Parameters:instance – the target instance
Returns:the number of CPUs and cumulative CPU time
Inspector.inspect_disk_rates(instance, duration=None)[source]

Inspect the disk statistics as rates for an instance.

Parameters:
  • instance – the target instance
  • duration – the last ‘n’ seconds, over which the value should be inspected
Returns:

for each disk, the number of bytes & operations read and written per second, with the error count

Inspector.inspect_disks(instance)[source]

Inspect the disk statistics for an instance.

Parameters:instance – the target instance
Returns:for each disk, the number of bytes & operations read and written, and the error count
Inspector.inspect_instances()[source]

List the instances on the current host.

Inspect the memory usage statistics for an instance.

Parameters:
  • instance – the target instance
  • duration – the last ‘n’ seconds, over which the value should be inspected
Returns:

the amount of memory used

Inspector.inspect_vnic_rates(instance, duration=None)[source]
