The Data Quality Monitor Via Teminator To Teminator For Host System Based On The Could Platform

There is gradually enriched function construction for provincial comprehensive network management system in CMCC Guangdong branch for many years.The capability to support product is growing and has become necessary facilitated system for normal operation.Along with the gradual presentation & steadily improvement for integrated network management systematical value and many important administrative solutions in security management area including IT system,internal risk control,higher requirement and expectation have been raised to protect data quality by province / city integrated network system.In order to analyze,search,appraisal and solve data quality problem for comprehensive network system in each application scenario and assure stability & dependence of data quality,A series of comprehensive network system improvement method should be constructed and strong systematical support has been offered to data quality management task.The system has followed principle including scalability,security,operability,reliability& maintainability.This system has offered strong flexibility and scalability through parameter driven & modular design.Along with the development of business & management,this system has expanded administration scope gradually with flexible configuration;Safety strategy & mechanism for whole system operation have been fully considered and different safety solution can be set according to various business requirement and application process;Chinese interface has been adopted in user interface indicating information being easy to understand.“Shortcut key” should be set to normal operation to realize prompt switching among functions;Reliability measures including fault tolerance & data storage backup for hardware and software has been fully considered;Designing according to maintainability principle and carrying out log record for major operation and being able to offer traceable function for each step of process when necessary.In summary,there are mainly following working contents:1)The common method for information collection in host system has been studied,as monitoring agent of gmond,real-time monitoring in seconds can be done during data monitoring process;2)Communication protocol between proxy & server side has been designed,XML data has been used for description so that the system will have excellent expansibility;3)The type selection for systematical service structure has been studied and related selection is mainly in REST,WebSocket.In consideration of the characteristics aslight-weight,dictionary data,static resources,monitored data inquiry & alarm query which inclined to traditional HTTP query/response mode i.e.communication mode of non-status;the pushing advantage for duplex communication & service for WebSocket cannot be exerted and REST will be more suitable for this system,so it has been chosen;4)Main feature for host performance data has been studied from data structure of system list including data structure,scope inquiry,flexibility,expansibility and distributed reading &writing operations and Cassandra has been used as memory database of whole system;5)Web management page of whole system has been designed & realized and operation situation for host has been demonstrated with many methods including color,lists,dial &curve.
