inspect_disk_info(instance, duration)

Inspect the disk information for an instance.

Parameters:

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

Returns:

for each disk , capacity , allocation and usage

inspect_disk_iops(instance, duration)

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 iops per second

inspect_disk_latency(instance, duration)

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 average disk latency

inspect_disk_rates(instance, duration)

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

inspect_disks(instance, duration)

Inspect the disk statistics 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, and the error count

inspect_instance(instance, duration)

Returns:

for each vNIC, the rate of bytes & packets received and transmitted

inspect_vnics(instance, duration)

Inspect the vNIC statistics for an instance.

Parameters:

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

Returns:

for each vNIC, the number of bytes & packets received and transmitted
