Abstract: To make up the deficiency of granularity and depth of existing containerized PaaS platform monitoring methods,an intelligent monitoring method was researched and implemented.In this method,the monitoring module dynamically adjusted the sampling period so that the sampling points were concentrated in the time period where the resource consumption occupancy of application system fluctuated greater;if the fluctuation amplitude exceeded the threshold,the system call data of application were collected and analyzed;the monitoring module integrated the statistical analysis results and the original monitoring data in time sequence and provides query interface,which could help the user located abnormalities or found performance bottlenecks.Compared with the existing monitoring scheme,the proposed method could reflect the change of application running state more finely.At the same time,dynamic data collection mechanism could effectively save the cost of computing and storage resources.
