Monitoring device, monitoring method and non-transitory computer readable medium

A monitoring method comprising:

• periodically acquiring status information from a printer having a consumable;
• determining, by a processor,
• a first state transition from an occurrence state of a consumable alarm to a release state of the consumable alarm, the release state being a state in which the consumable alarm is cleared, and
• a second state transition from the release state of the consumable alarm to the occurrence state of the consumable alarm based on the status information periodically acquired;
• if the first state transition is determined, determining, based on the status information periodically acquired, as to whether the determined first state transition is an apparent first state transition or an actual first state transition;
• if the actual first state transition is determined and then the second state transition is determined, notifying an alarm relating to the consumable to an administrator;
• and
• if the apparent first state transition is determined and then the second state transition is determined, suppressing the alarm related to the consumable.

A non-transitory computer readable recording medium storing a program that causes a computer to execute a monitoring process, the monitoring process comprising:

• periodically acquiring status information from a printer having a consumable;
• determining
• a first state transition from an occurrence state of a consumable alarm to a release state of the consumable alarm, the release state being a state in which the consumable alarm is cleared, and
• a second state transition from the release state of the consumable alarm to the occurrence state of the consumable alarm
• based on the status information periodically acquired;
• if the first state transition is determined, determining, based on the status information periodically acquired, as to whether the determined first state transition is an apparent first state transition or an actual first state transition;
• if the actual first state transition is determined and then the second state transition is determined, notifying an alarm relating to the consumable to an administrator;
• and
• if the apparent first state transition is determined and then the second state transition is determined, suppressing the alarm related to the consumable.

A monitoring device comprising:

• an acquiring unit that periodically acquires status information from a printer having a consumable;
• a first determination unit that determines
• a first state transition from an occurrence state of a consumable alarm to a release state of the consumable alarm and
• a second state transition from the release state of the consumable alarm to the occurrence state of the consumable alarm
• based on the status information periodically acquired by the acquiring unit;
• a second determination unit, wherein if the first state transition is determined, the second determination unit determines, based on the status information periodically acquired by the acquiring unit, as to whether the determined first state transition is an apparent first state transition or an actual first state transition;
• and
• a notification unit, wherein if the actual first state transition is determined and then the second state transition is determined, the notification unit notifies an alarm relating to the consumable to an administrator,
• wherein
• the acquiring unit includes
• a stationary polling execution section that executes stationary polling to periodically acquire the status information from the printer, and
• a scrutiny polling execution section that executes, for the printer, scrutiny polling for a shorter period than that for which the stationary polling is executed,
• the second determination unit determines as to whether the first state transition is the apparent first state transition or the actual first state transition, by referencing at least status information acquired by the scrutiny polling, and
• wherein the scrutiny polling execution section executes the scrutiny polling before a next stationary polling is executed after the first determination unit determines the first state transition.
