Data compression in a distributed monitoring system

摘要

A distributed monitoring system comprises a plurality of agents configured for communication with at least one central server. A given one of the agents obtains measurement data, and applies a statistical test to the measurement data. Based on a result of the statistical test, the given agent determines whether or not an update needs to be sent by the agent to the central server. The agent sends the update to the central server if the determination indicates that the update should be sent.

1. A method comprising:
obtaining a first set of measurements by a first agent, the first set of measurements being associated with a quality-of-service metric of a communication path between the first agent and a second agent measured at a first time; sending a first update associated with the first set of measurements from the first agent to a central server at a second time later than the first time; obtaining a second set of measurements by the first agent, the second set of measurements being associated with the quality-of-service metric of the communication path measured at a third time later than the second time; and sending a second update associated with the second set of measurements from the first agent to the central server at a fourth time later than the third time when the first agent determines that a distribution of the first set of measurements differs from a distribution of the second set of measurements, wherein the second update comprises at least one of (i) a report characterizing the first set of measurements, (ii) a portion of the first set of measurements, (iii) a code characterizing the first set of measurements, and (iv) a message characterizing the first set of measurements.
