Given a “budget” (defined as the maximum volume of logs allowed to be output in a time interval), Log² makes the “whether to log” decision through a two-phase filtering mechanism. In the first phase, a large number of irrelevant logs are discarded efficiently. In the second phase, useful logs are cached and output while complying with logging budget. In this way, Log² keeps the useful logs and discards the less useful ones. We have implemented Log² and evaluated it on an open source system as well as a real-world online service system from Microsoft. The experimental results show that Log² can control logging overhead while preserving logging effectiveness.]]> Wed 11 Apr 2018 13:44:54 AEST ]]> Cross-dataset time series anomaly detection for cloud systems https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48346 Tue 14 Mar 2023 18:46:36 AEDT ]]> Fighting the Fog of War: Automated Incident Detection for Cloud Systems https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47921 Thu 09 Feb 2023 10:35:54 AEDT ]]> Improving service availability of cloud systems by predicting disk error https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35051 Fri 14 Jun 2019 12:45:40 AEST ]]>
