Abstract
The present invention provides an attribute value sampling device that obtains communication path establishing control information transmitted and received between data transfer devices, and sets monitoring on the basis of the communication path establishing control information. The attribute value sampling device obtains control information for establishing the communication path sent between the data processors, and extracts setting information relative to the obtaining the attribute value from the obtained communication path establishing control information, and obtains the attribute value from information passing through the path by using the extracted setting information.
Claims10
A communication path monitoring system for monitoring a communication path established through a transmission link for connecting data processors, comprising:
- an attribute value sampling device for sampling an attribute value of the communication path as a monitoring object, the attribute value sampling device being coupled to at least one of the transmission link and a data processor, and
- wherein the attribute value sampling device:
- obtains control information for establishing the communication path;
- extracts setting information relative to obtaining of the attribute value from the communication path establishing control information, and
- obtains the attribute value from information passing through the communication path by using the extracted setting information.
