Control system computer, method, and program for monitoring the operational state of a system

A control system comprising:

• a control computer;
• and a computer monitored by said control computer;
• wherein said monitored computer includes:
• a control section for, based on an operation performance metric value of each of a plurality of first monitored items, determining a second monitored item and obtaining an operation performance metric value of said second monitored item, said second monitored item being associated with said each first monitored item, and
• an interface for transmitting said obtained operation performance metric value;
• and
• wherein said control computer includes:
• an interface for receiving said operation performance metric value from said monitored computer, and
• a control section for monitoring an operational state of a system based on said operation performance metric value,
• wherein when said operation performance metric value of said each first monitored item is within a risk range, the number of second monitored items is increased, thereby intensively monitoring closely related monitored items, and
• wherein when said operation performance metric value of said each first monitored item is outside of the risk range, the number of second monitored items is reduced, thereby not intensively monitoring closely related monitored items.

A control computer for monitoring an operational state of a system, comprising:

• an interface for receiving an operation performance metric value of each of a plurality of first monitored items from a monitored computer;
• and
• a control section for, based on said operation performance metric value of said each first monitored item, determining a second monitored item and instructing said monitored computer to obtain an operation performance metric value of said second monitored item, said second monitored item being associated with said each first monitored item,
• wherein when said operation performance metric value of said each first monitored item is within a risk range, the number of second monitored items is increased, thereby intensively monitoring closely related monitored items, and
• wherein when said operation performance metric value of said each first monitored item is outside of the risk range, the number of second monitored items is reduced, thereby not intensively monitoring closely related monitored items.

A control method for monitoring an operational state of a system, comprising the steps of:

• based on an operation performance metric value of each of a plurality of first monitored items received from a monitored computer object, determining a second monitored item, said second monitored item being associated with said each first monitored item;
• instructing said monitored computer to obtain an operation performance metric value of said second monitored item;
• and
• sending the obtained performance metric value to a monitoring computer, thereby permitting the operational state of the system to be monitored,
• wherein when said operation performance metric value of said each first monitored item is within a risk range, the number of second monitored items is increased, thereby intensively monitoring closely related monitored items, and
• wherein when said operation performance metric value of said each first monitored item is outside of the risk range, the number of second monitored items is reduced, thereby not intensively monitoring closely related monitored items.

A control program, stored on a storage medium, for monitoring an operational state of a system, said control program, when executed, causes a computer to perform the steps of:

• based on an operation performance metric value of each of a plurality of first monitored items received from a monitored computer object, determining a second monitored item, said second monitored item being associated with said each first monitored item;
• and
• instructing said monitored computer to obtain an operation performance metric value of said second monitored item and to send the obtained performance metric value to a monitoring computer,
• wherein when said operation performance metric value of said each first monitored item is within a risk range, the number of second monitored items is increased, thereby intensively monitoring closely related monitored items, and
• wherein when said operation performance metric value of said each first monitored item is outside of the risk range, the number of second monitored items, thereby not intensively monitoring closely related monitored items.
