Managing commands

Managing custom commands

Custom commands are a feature of the cloud assistant designed to meet your personalized O&M requirements. When preset public commands can not meet your requirements, you can create custom commands. After this, you can run the custom commands you have written on multiple instances at the same time via O&M tasks.

Usage notes

In the same region, the maximum number of custom commands you can create is 500, and the content size of a custom command must not exceed 16 KB.

You can configure custom commands to be used only by specific IAM users. For detailed operations, refer to Configuring permissions for using custom commands.

Create custom commands

You can create custom commands as needed and use them to create O&M tasks.

tip

You can also create custom commands by using the public command cloning feature. For operation details, refer toCloning into custom commands.

In the left-side navigation pane, select "Maintenance & Monitoring > Cloud Assistant" and then select the "Custom commands" tab.

In the top menu bar, select the region where your business is located.

Click the "Confirm" button to create a custom command.
