What can I do if VCN3010 log collection fails?

To analyze software issues, collect log information in the diag.log, log.log, diagnose.log (one-click logs are the most important) files.

To analyze hardware issues, collect log information in the diag.log, log.log, diagnostic_information.zip (memory logs, which are the most important logs) files, and other related command lines.

Collect log information using either of the following methods:

1. Collect diagnostic logs in one click.

<HUAWEI>system-view
[~HUAWEI] diagnose
[~HUAWEI-diagnose] display diagnostic-information >> diagnose.log

Note:
1. Executing the command takes about 5 minutes. Please wait.
2. The diagnose.log file is exported to the root directory of the active MPU.

< HUAWEI >cd flash:
<~HUAWEI >dir

3. Collect log information in the diag.log, log.log, and diagnostic_information.zip files.

<HUAWEI>system 
[~HUAWEI] diagnose
[~HUAWEI-diagnose] collect diagnostic information
[~HUAWEI-diagnose] return
<HUAWEI >save logfile
<HUAWEI > cd logfile:
<HUAWEI >dir

Note:
You can run the mput * command to collect all logs.
[ftp]mput *

3. Run the following command lines to collect information to analyze hardware issues.

[~HUAWEI]
