Network Intelligence Service:Identifikasi Anomali dan Troubleshooting

Scenarios

NIS mengidentifikasi anomali jaringan dan menentukan akar penyebabnya melalui troubleshooting instans, jalur, dan traffic, sehingga menjamin kelangsungan bisnis.

Monitor Event Center untuk Mengidentifikasi Anomali

Alibaba Cloud secara proaktif mendeteksi event jaringan berdasarkan definisi event yang telah dikustomisasi, mengirimkan alert, dan menampilkannya di konsol. Pantau Event Center untuk menerima alert terkait anomali jaringan—seperti kehilangan paket akibat pelanggaran ambang batas—dan identifikasi instans yang bermasalah. Untuk informasi selengkapnya, lihat Event Center Overview.

1. Log on to the NIS console.

2. In the left-side navigation pane, click Event Center.

3. On the Event Center page, you can see that TransitRouter instances have failed and the bandwidth of an Elastic IP Address (EIP) has exceeded its limit.

   

Initiate Real-time Diagnostics for Abnormal Instances

You can initiate diagnostics for abnormal TR instances detected by the Event Center to obtain exception reports and handling suggestions. For more information, see Work with instance diagnostics.

1. Log on to the NIS console.

2. In the left-side navigation pane, choose Self-diagnostics > Instance Diagnostics.

3. On the Instance Diagnostics page, click Diagnose Instance.

4. In the Instance Health Diagnostics dialog box, configure the instance information, then click Start.

5. In the Diagnostic Details panel, view the diagnostic progress, result statistics, and specific diagnostic details for the instance.

   

   

Troubleshoot Bandwidth Saturation Issues

When business bandwidth utilization remains consistently high, use NIS Traffic Analyzer to analyze traffic composition and quickly identify instances or IP addresses consuming excessive bandwidth.

1. Create an NIS Traffic Analyzer

2. Create VPC or TR flow logs as data sources

3. View the VPC Traffic Chart or TR Traffic Chart, and use TopN Traffic Trend to identify instances or IP addresses consuming high bandwidth.

Troubleshoot Network Connectivity Issues

If a network connection fails, use path analysis to identify breakpoints. For more information, see Using Path Analysis.

1. Log on to the NIS console.

2. On the Reachability Analyzer page, click Start Analyzing.

3. On the Start Analysis page, configure the parameter information.

   

4. Select whether to save the path. The default value is No.

5. Click Start Analysis and view the Internet analysis results.
