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 two 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 the transmission link or one of the data processors;
- and
- wherein the attribute value sampling device:
- obtains control information for establishing the communication path, the control information being exchanged between the two data processors,
- extracts setting information relative to obtaining of the attribute value from the communication path establishing control information if the control information is obtained,
- obtains the attribute value from information passing through the communication path by using the extracted setting information,
- establishes monitoring of the communications path synchronously with the establishment of the communications path if the attribute value is obtained, and
- in response to a change to the communications path, modifies the monitoring of the communications path synchronously with the change to the communications path.
