Profiling distributed systems in lightweight virtualized environments with logs and resource metrics
Aidi Pi, Wei Chen, Xiaobo Zhou, Mike Ji · 2018
Understanding and troubleshooting distributed systems in the cloud is considered a very difficult problem because the execution of a single user request is distributed to multiple machines. Further, the multi-tenancy nature of cloud environments further introduces interference that causes performance issues. Most existing troubleshooting tools either focus on log analysis or intrusive tracing methods, leaving resource usage monitoring unexplored.
