Bases: object

Implementation of the ‘UsageAndPerformanceStats’ model.

Provides usage and performance statistics for entities such as a disks, Nodes or Clusters.

Attributes:

data_in_bytes (long|int): Specifies the data read from the protected

objects by the Cohesity Cluster before any data reduction using deduplication and compression.

data_in_bytes_after_reduction (long|int): Morphed Usage before data is

replicated to other nodes as per RF or Erasure Coding policy.

min_usable_physical_capacity_bytes (long|int): Specifies the minimum

usable capacity available after erasure coding or RF. This will only be populated for cluster. If a cluster has multiple Domains (View Boxes) with different RF or erasure coding, this metric will be computed using the scheme that will provide least saving.

num_bytes_read (long|int): Provides the total number of bytes read in

the last 30 seconds.

num_bytes_written (long|int): Provides the total number of bytes

written in the last 30 second.

physical_capacity_bytes (long|int): Provides the total physical

capacity in bytes of all the storage devices, after subtracting space reserved for cluster services

read_ios (long|int): Provides the number of Read IOs that occurred in

the last 30 seconds.

read_latency_msecs (float): Provides the Read latency in milliseconds

for the Read IOs that occurred during the last 30 seconds.

system_capacity_bytes (long|int): Provides the total available

capacity as computed by the Linux ‘statfs’ command.

system_usage_bytes (long|int): Provides the usage of bytes, as

computed by the Linux ‘statfs’ command, after the size of the data is reduced by change-block tracking, compression and deduplication.

total_physical_raw_usage_bytes (long|int): Provides the usage of

bytes, as computed by the Cohesity Cluster, before the size of the data is reduced by change-block tracking, compression and deduplication.

total_physical_usage_bytes (long|int): Provides the data stored

locally, after the data has been reduced by deduplication and compression, including the space required for honoring the resiliency settings (EC/RF).

write_ios (long|int): Provides the number of Write IOs that occurred

in the last 30 seconds.

write_latency_msecs (float): Provides the Write latency in

milliseconds for the Write IOs that occurred during the last 30 seconds.

classmethod from_dictionary(dictionary)

Creates an instance of this model from a dictionary

Args:

dictionary (dictionary): A dictionary representation of the object as obtained from the deserialization of the server’s response. The keys MUST match property names in the API description.

Returns:

object: An instance of this structure class.
