Monitoring network connections

A computer implemented method for monitoring a network connection for determining a performance issue in a network, the method comprising:

• setting a default sampling rate for monitoring the network connection;
• continuously monitoring the network connection at the default sampling rate;
• identifying a new communication occurring via the network connection;
• obtaining performance metrics for the new communication;
• comparing the performance metrics for the new communication with a threshold;
• if the comparing indicates a possible performance degradation in the new communication, adapting the first sampling rate to a second sampling rate greater than the first sampling rate so as to determine whether the performance degradation in the new communication is attributable to the network connection;
• and
• if the comparing indicates no current performance degradation in the new communication, adjusting the threshold to a raised threshold to reduce a likelihood of false positives in future comparisons.

A computer implemented method for determining a performance issue in a communication over a network connection in a network, the method comprising:

• establishing a threshold for quality of communication via the network connection;
• identifying a new communication occurring via the network connection;
• sampling a parameter of the new communication at a first sampling rate;
• comparing the sampled parameter with the threshold and marking the sampled parameter as either acceptable or not acceptable based on the comparing;
• storing the sampled parameter in a call log and adding the marking of the sampled parameter to a buffer;
• analyzing contents of the buffer to determine if a quality issue exists in respect of the new communication:
• if a quality issue exists, sampling the parameter at a second sampling rate higher than the first sampling rate, and
• if no quality issue exists, continuing to sample the parameter at the first sampling rate;
• after the new communication ends, aggregating sampled parameters stored in the call log and using the aggregated sampled parameters to update the threshold for quality of communications via the network connection.
