A transaction time measurement mechanism has a transaction time manager running on a server computer system, a transaction time agent running on a client computer system that is coupled to the server computer system via a network, and a simple protocol for allowing them to directly and efficiently communicate. The transaction time agent is configured according to configuration data stored in a configuration table in a transaction time database, and stores transaction time data in a statistics table according to this configuration. The data in the statistics table is indexed to allow retrieving only the transaction time data of interest. The simple communication protocol supports multiple transaction time managers in a network computing environment that may all communicate with a single client.

A packet communications network includes a centrally controlled route testing system in which each node includes test results tables containing the results of all path tests originated at that node. A centralized route management facility initiates a path test originating at any node by remotely altering a trigger value in a trigger data object at that node. A general results table contains general test results for an entire path between the local node and a remote node while a detailed test results table contains detailed, hop-by-hop test results for each transmission leg of a multi-leg path. The general results table contains a name trigger field for identifying a point-to-point path to be tested, and a connection trigger field for identifying a link-by-link path to be tested.
