Collect Information About Process Suspension

The information can be collected manually or automatically.

Manual collection: Collect host and device logs and files. Only the minimum set of information is collected.
Automatic collection: On the host server, use the asys tool to collect all fault-related information, including the installation version information, device health status information, dump files, operator compilation information, and full log files.
Note: The asys tool can be used to collect fault information in only limited scenarios, excluding cluster, container, virtual machines, and cloud.

Manual Collection

To collect application logs and trace logs, perform the following steps:

Plan a directory for storing log files on the host server, for example, ${HOME}/err_log_info/.
The default path of application log files is ${HOME}/ascend/log on the host server. Move the log files to the err_log_info directory.
```
mv ${HOME}/ascend/log ${HOME}/err_log_info/ 
```
The default path of trace log files is $HOME/ascend/atrace/ on the host server. Move the log files to the err_log_info directory.
```
mv $HOME/ascend/atrace ${HOME}/err_log_info/ 
```

For details about log levels, log paths, and log files, see Log Reference.
