NETWORK MONITORING APPARATUS, NETWORK MONITORING METHOD AND RECORDING MEDIUM
First Claim
1. A network monitoring apparatus in communication with a monitoring target apparatus through a network, comprising:
- a traffic receiver that receives traffic values transmitted from the monitoring target apparatus;
a traffic accumulator that accumulates the traffic values;
a traffic calculator that calculates a traffic calculation value by using the accumulated traffic values; and
a congestion judger that compares a judgment target value, corresponding to a traffic value as a congestion judgment target from the accumulated traffic values, with the traffic calculation value as a threshold value, and judges based upon the comparing whether the monitoring target apparatus is congested.

Abstract
A network monitoring apparatus that is in communication with a monitoring target apparatus through a network, receives traffic values transmitted from the monitoring target apparatus, accumulates the traffic values, calculates a traffic calculation value for judging congestion of the monitoring target apparatus by using the traffic values, and using a judgment target value corresponding to a traffic value as a congestion judgment target from the traffic values transmitted from the monitoring target apparatus and the traffic calculation value as a threshold value, compares the judgment target value and the threshold value. The apparatus judges whether the monitoring target apparatus is congested with traffic by using the comparison result.

18. A method of monitoring a network, comprising:
-
saving traffic values; calculating a traffic calculation value based upon the saved traffic values; and using a judgment target value, corresponding to a traffic value as a congestion judgment target, from the saved traffic values and a threshold and/or the traffic calculation value as the threshold value and comparing the judgment target value with the threshold value; and judging congestion according to the comparing.

19. A computer-readable recording medium storing a computer program judging congestion of a monitoring target apparatus by using traffic values transmitted from the monitoring target apparatus, the computer program causing a computer to execute operations comprising:
-
receiving traffic values transmitted from the monitoring target apparatus; accumulating the traffic values; calculating a traffic calculation value used for congestion judgment by using the accumulated traffic values; and comparing a judgment target value, corresponding to a traffic value as a congestion judgment target, from the traffic values transmitted from the monitoring target apparatus with a threshold value and/or the traffic calculation value as the threshold value; and judging congestion of the monitoring target apparatus according to the comparing.
