1. A monitoring device, comprising:

  • a status data receiving part that receives status data representing a status of a monitored device from the monitored device through a communication network;

    a condition storing part that stores a condition for prediction;

    a status monitoring part that compares the status data with the condition for prediction in the condition storing part so as to predict an abnormality,wherein the condition for prediction includes a condition for prediction created based on a change pattern of the status data that provides an indication of the abnormality, the status data being obtained before a point in time at which the abnormality is caused in the monitored device;

    a data storing part that accumulates the status data received from the monitored device; and

    an abnormality analyzing part that newly creates the condition for prediction based on a transition of the status data before the point in time at which the abnormality is caused using the status data accumulated in the data storing part and has the condition for prediction stored in the condition storing part,wherein when the status data meets either of the condition for prediction newly created by the abnormality analyzing part or the condition for prediction prestored in the condition storing part, the status monitoring part judges that there is a high possibility of occurrence of the abnormality.
