In an operation monitoring device which groups a plurality of types of performance information and focuses on monitoring the representative of the grouped performance information, abnormality of the non-representative of the performance information is also monitored efficiently without increasing a monitoring load at ordinary times. Monitoring condition alteration units 12 and 23 make a performance information collection unit 11 perform collection of the representative of the performance information grouped by the performance information grouping unit 22 at a predetermined interval, and make the performance information collection unit 11 stop collection of the non-representative of the performance information or make the performance information collection unit 11 perform collection thereof at an interval longer than the interval for the representative of the performance information, and further, in case that a fluctuation rate or a fluctuation amount of the representative of the performance information exceeds a predetermined threshold value, make the performance information collection unit 11 start collection of the non-representative of the performance information or make the performance information collection unit 11 perform collection thereof at an interval shorter than ordinary times.
