1. A computer network system, for collecting (at a client-node) network and computer information (temporally adjacent to a user-perceived computing performance anomaly) from connectivity resource nodes at a time determined by user action, comprising: a) client computer network-node means for networking with a plurality of network connectivity resource nodes; b) wherein said client computer network-node means comprises information collector computer processor means for collecting network and computer information temporally adjacent to at least one user-perceived computing performance anomaly occurring on said client computer network-node means, comprising i) anomaly user-indicator means for accepting indication, by a user action, of an advent of the at least one user-perceived computing performance anomaly; ii) wherein anomaly user-indicator means accepts the indication temporally adjacent to the advent of the at least one user perceived computing performance anomaly; and iii) time marker computer processor means for marking a time (t) of the user action indicating the at least one user-perceived computer performance anomaly, iv) client-computer operations-state information collector computer processor means for collecting client-computer operations-state information temporally adjacent such time (t), v) network connectivity path map computer processor means for mapping network connectivity resource nodes along network connectivity paths actively in use by said client computer network-node means temporally adjacent such time (t), vi) network connectivity node-state information requestor computer processor means for requesting network connectivity node-state information, from such network connectivity resource nodes along such network connectivity paths, temporally adjacent such time (t), vii) information gatherer computer processor means for gathering such client-computer operations-state information, such network connectivity paths, and such network connectivity node-state information, and viii) information computer storer means for storing such gathered such client-computer operations-state information, such network connectivity paths, and such network connectivity node-state information; and c) wherein such network and computer information comprises such client-computer operations-state information, such network connectivity paths, and such network connectivity node-state information; and d) wherein said user computer network-node means collects network and computer information temporally adjacent to the at least one user-perceived computing performance anomaly indicated at such time (t).
