Usage Guide

Assume that the confpath configuration file directory has been initialized.

To enable only the trend prediction function, run the following command (for details, see the description of the service subcommand):
```
gs_dbmind service start -c confpath --only-run forecast
```
To enable trend prediction in interactive mode, run the following command and view the prediction result of an instance metric from timestamps0 to timestamps1:
```
gs_dbmind component forecast show -c confpath --metric-name metric --host instance --start-time timestamps0 --end-time timestamps1
```
Run the following command to manually clear historical prediction results:
```
gs_dbmind component forecast clean -c confpath --retention-days DAYS
```
To enable trend prediction based on the user-defined threshold (up and low), run the following command and view the prediction result of the metric of an instance from timestamps0 to timestamps1 and check whether the prediction value exceeds the threshold:
```
gs_dbmind component forecast early-warning -c confpath --metric-name metric --host instance --start-time timestamps0 --end-time timestamps1 --upper up --lower low
```
Run the following command to stop the services that have been started:
```
gs_dbmind service stop -c confpath
```
