background
The auto parts electronic atlas system is an important business system of a certain car. The business department reported that when the electronic atlas of auto parts calls for drawings, the access is slow.
The automobile headquarters has deployed the NetInside traffic analysis system, using the traffic analysis system to provide real-time and historical raw traffic. This analysis focuses on the analysis of the performance of the auto parts electronic atlas system for security forensics, performance analysis, network quality monitoring and deep network analysis.

Analysis conclusion
The Net Inside system locates the root cause of the problem in a few seconds, and demonstrates in detail the slow access analysis process of the electronic atlas of auto parts through the output report.
1. Slow visits: 3.7% of the visits were slow visits, that is, 60,298 visits were made in the past week , and the visits lasted more than 5 seconds.
Analyzed the first slow access, the client 192.168.17.10, the access time was 119 seconds , the main reason is that the server response time is too long.
Analyzed the second slow access, the client 192.168.17.19, the access time was 1268 seconds, the main reason is that the server response time is too long.
2. 500 error report : There are 8682 HTTP 500 page errors in the analysis.
Detailed analysis content
System overview
Business system health
Through the weighted calculation of key performance indicators such as page errors, user experience, and slow pages, combined with big data perception technology, the system calculates that the health score of the electronic atlas of auto parts is less than 60 points.
Comprehensive analysis of system performance
From April 4th to April 10th, there were 60,298 slow visits and 8,682 HTTP 500 errors in the electronic atlas of auto parts.
System Performance Analysis
Visit volume and visit distribution trend in the past week, nearly 30,000 visits per hour during working hours.
The number of slow visits and distribution trend in the past week, about 800 slow visits per hour during working hours, the highest one was on April 9, reaching 4131 slow visits (you can see the number of normal page visits by hiding them).
Sorting according to the number of slow pages, view the slow access information of the electronic catalog of auto parts.
The first page family has a total of 305,588 visits, of which 2372 are slow visits, accounting for 0.7%.
The first slow page performance analysis
Detailed display of the slow access to the first 5 single pages, the 5 pieces of information in the electronic atlas of auto parts, the access completion time exceeds 5 seconds (the time is accurate to microseconds).
Analyze this article in depth to see the specific reasons for the slowness.
Expand this visit to view the specific details. When accessing the first response object in this visit, the access time reached 118 seconds (click the + sign to view the specific response object).
The distribution of 119 seconds is shown in detail due to high server response times.
The second slow page performance analysis
Double-click the second statement family to view detailed information about a single statement.
5 single page slow visits are displayed in detail. When accessing this information, the completion time exceeds 5 seconds, and the highest completion time reaches 1268 seconds.
In-depth analysis of the first slow access, the client is 192.168.17.19.
Expand this access to view the details. The same object has been accessed, and the server response time is different each time.
The distribution of 1268 seconds is shown in detail. Without knowing the business, the system has detected that it has been repeatedly visited many times, resulting in a long response time from the server. The reason may be that the page has set up an access mechanism.
System error analysis
The distribution trend of HTTP 500 errors in the electronic catalog of auto parts. On April 9, there were a large number of errors reported, and there were 5747 HTTP 500 response codes.
After further checking the error information, the analysis shows that there are a large number of HTTP 500 error reports when accessing these page clusters. Double-click the first statement family to view detailed error information.

suggestion
Through the analysis of the performance data of the electronic atlas of auto parts, it was found that the cause was caused by the long response time of the server, which was a software problem and had nothing to do with the network. If you want to solve this problem, it is recommended to contact the software developer and ask them for technical optimization support.
