Foshan Telecom's major customer network troubleshooting test
Fault description:
The customer reported that the telecom line and the Hong Kong head office video conference were very card, the packet loss was serious, and the change to Unicom was smooth. After being reflected in the relevant maintenance department of Foshan Telecom, after a week of investigation, no fault point was found. Foshan Telecom reported that the group could not find the source of the fault. No one in the Hong Kong company cooperated with the investigation, and then remotely cooperated with the NetPilot.NVPN system. Fault testing and positioning.
Test method:
From Foshan, the company initiated tests on advanced ping, maximum network throughput and route quality for Hong Kong companies. The uplink and downlink data from Foshan to Hong Kong are quite different. It is speculated that there is a fault in the path from Hong Kong back to Foshan, and then we conduct route quality testing. From the route quality test chart, it can be seen that from the Hong Kong company to the Foshan company, one hop route is very large, and the route quality from Foshan to Hong Kong is relatively good. It is inferred that the customer fault is due to the 12th hop. Caused by route congestion.
Summary:
Tested from both ends, it is found that the difference between the uplink and downlink test data is large, which is presumed to be due to a problem in the network path in a certain direction.
Then, the route quality test was carried out. From the path of the Hong Kong company to Foshan, it was found that one hop route was very large, and the route quality from Foshan to Hong Kong was relatively good. It was concluded that the customer failure was caused by route congestion.
After locating the fault point, Foshan Telecom maintenance personnel specifically checked the path and found that it was a fault caused by relay congestion, and routing optimization could solve the problem.
Bank branch trading system performance monitoring
Deployment instructions:A test center server is deployed at the central point, and a test probe test is deployed at the central point and each branch office to monitor network availability and service availability, and to identify faults unless SMS alerts.
Power Supply Bureau data center application fault monitoring
Deployment requirements:
Monitoring/troubleshooting application server groupDeployment background:
Backgound: Thedata center server is used to provide services to the end customer
Protocol: SQL, WEB.Due to frequent upgrades of server applications, it is necessary to monitor failed links. Network administrators want to monitor/capture all data that fails to communicate between servers; when communication fails, you can further analyze the cause of the identification.
Solution:deploy 2 test terminals at the IDC portal, poll all application servers;deploy WEB, database and other monitoring tasks;
batch enter the URL of the service provided, simulate the user to conduct transactions, and timely find the application with errors;
user-defined threshold Alarm notification.
Government tax system service performance monitoring and network optimization
User Experience Management is a continuous acquisition of end-user application response time, providing global real-time information for all transactions and users within the enterprise, such as login, browsing, query, submission and payment, providing a multi-angle and comprehensive customer experience. Attempting to solve the background technology monitoring based on database and middleware can not fully describe the whole picture of the business and application system, resulting in many monitoring dead ends, and even the problems that the user end can't actually use the business system and the monitoring still has not been monitored.
Application performance, availability, etc.;
configurable warning content;
reproducible failure or delay process;
record performance experience;
count success rate of all key transactions, average response time, transaction volume;
analyze network performance for bottlenecks, and provide network Evaluation of expansion
