  • Method of monitoring a computer system, featuring performance data distribution to plural monitoring processes
    Patent number: 5961596
    Abstract: In order to enable monitoring of a computer of a monitoring target, by two or more computers by way of a network, without increasing the load of the computer of monitoring target, the capturing process invoked on each node of the parallel computer captures performance data, the collecting process invoked on a specific node collects these captured performance data, and transmits to the relaying process on the monitoring computer. If there is a display process and a logging process invoked on the same or different monitoring computers, the relaying process distributes the performance data to them. The display process displays the performance data for part of measurement items included in the distributed performance data on the display device. The logging process stores all the distributed performance data in the storage device.
