A novel development and analysis solution to PaaS log by using CouchDB
Zhihan Liu, Yuhua Wang, Rongheng Lin · 2012
Log for PaaS cloud computing system is important to provide information to manage systems. In this paper, we design and implement a PaaS log system by providing log recording ability to other parts of PaaS system as a webservice. This system uses Log4j as log frame and CouchDB as database to analyze logs due to its data structure, efficient log analysis using Map Reduce and fore-end visualization. Also, we analyze system load, webservice load, VM load and DB load based on this PaaS log system and real data. At last, future analysis using our PaaS log system and system optimizations are discussed.
