Storage monitoring system and monitoring method therefor

A storage monitoring system including a storage device, a manager, and a plurality of agents,

• the storage device comprising:
• a plurality of types of components,
• the plurality of types of components including a plurality of components of a first type,
• the manager comprising:
• a first processor and a first memory,
• wherein the first processor
• stores information representing a first monitoring range of the plurality of components of the first type to be monitored by a first agent out of the plurality of agents in association with information representing the first agent in the first memory and notifies the first agent of the information representing the first monitoring range;
• and
• stores information representing a second monitoring range of the plurality of components of the first type to be monitored by a second agent out of the plurality of agents in association with information representing the second agent in the first memory and notifies the second agent of the information representing the second monitoring range,
• the first agent comprising:
• a second processor and a second memory,
• wherein the second processor stores the information representing the first monitoring range notified from the manager into the second memory, acquires, from the storage device, first component metric information on components in the first monitoring range out of the plurality of components of the first type, based on the information representing the first monitoring range stored in the second memory, and stores the acquired first component metric information into the second memory,
• the second agent comprising:
• a third process and a third memory,
• wherein the third processor stores the information representing the second monitoring range notified from the manager into the third memory, acquires, from the storage device, second component metric information on components in the second monitoring range out of the plurality of components of the first type, based on the information representing the second monitoring range stored in the third memory, and stores the acquired second component metric information into the third memory.
