Testing media topology for collaboration sessions
In one embodiment, a device may obtain a media topology of nodes involved in a collaboration session. The device may cause each of a plurality of probes to be provisioned to a corresponding node of the nodes involved in the collaboration session to perform a test of a corresponding segment of the media topology, and each of the plurality of probes may be associated to a session identifier of the collaboration session. The device may determine observability information based on results of the plurality of probes for each segment of the media topology, and the results may include an indication of the session identifier. The device may correlate the observability information to the collaboration session based on the indication of the session identifier.

determining that an existing probe associated to another session identifier corresponds to a segment of the media topology involved in the collaboration session; and
associating the session identifier of the collaboration session to the existing probe.
14. A tangible, non-transitory, computer-readable medium having computer-executable instructions stored thereon that, when executed by a processor on a computer, cause the computer to perform a method comprising:
making a determination that telemetry data received from a node of nodes involved in a collaboration session exceed an impairment threshold or that a customer issue report for the collaboration session has been obtained;
obtaining, in response to the determination, a media topology of the nodes involved in the collaboration session;
causing each of a plurality of probes to be provisioned to a corresponding node of the nodes involved in the collaboration session to perform a test of a corresponding segment of the media topology, wherein the plurality of probes include an audio type test probe or a video type test probe that is selected based on the media topology, further wherein each of the plurality of probes is associated to a session identifier of the collaboration session;
determining observability information based on results of the plurality of probes for each segment of the media topology, wherein the results include an indication of the session identifier; and
correlating the observability information to the collaboration session based on the indication of the session identifier.
15. The tangible, non-transitory, computer-readable medium as in claim 14 , the method further comprising:
determining that an existing probe associated to another session identifier corresponds to a segment of the media topology involved in the collaboration session; and
associating the session identifier of the collaboration session to the existing probe.
16. The tangible, non-transitory, computer-readable medium as in claim 14 , wherein the observability information is an aggregation of the results of a portion of the plurality of probes including an indication of a same session identifier.
