Table 1 COC best practices

Practice

Description

Handling Alarms Based on Fault Management on COC

This section describes how to clear a raw alarm using an alarm ticket and notify the corresponding owner based on shift management. The owner handles the alarm ticket, locates and rectifies the fault, and clears the alarm. If an alarm cannot be cleared, it can be transferred to an incident ticket, escalated, or handled through a war room.

Performing a Fault Drill of High Memory Usage on COC

This section describes how to perform a fault drill of high memory usage on COC and create an improvement ticket to follow up the improvement items.

Identifying Compliance Issues Using Patch Scan on COC

This section describes how to use COC to scan OS patches, provide compliance reports, and fix non-compliant patches.

Saving Costs Through Scheduled Startup and Shutdown on COC

This section describes how to use the scheduled O&M function of COC to automatically start and stop ECSs at a scheduled time, thereby reducing the cloud resource operation cost.

Using COC to Batch Execute Commands for Multiple ECSs

This section describes how to use the batch command execution function of COC to send commands to multiple ECSs at the same time. This function helps build a standard, automated, and auditable O&M process, upgrading the original manual serial O&M to automated parallel O&M.

Upgrading OSs in Batches Using COC

This section describes how to use the OS version change function of COC to upgrade OSs in batches for multiple hosts. This function eliminates the need to manually upgrade OSs one by one, greatly improving the OS upgrade efficiency.

Automatically Notifying Users When OS Patch Scanning Fails

This section describes how to use COC to periodically scan OS patches and automatically notify users of scanning failures. This function enables real-time notifications for failed incidents, quick root cause locating, and closed-loop problem handling.

Changing Passwords in Batches Using the COC Account Baselines

This section describes how to use the COC account management function to provide the account baseline capability and automatically change passwords in batches for existing resources, implementing unified control, security compliance, and efficient O&M.

Changing the ECS Hostname Using a Script

This section describes how to use the script management function of COC to change the ECS hostname online in a standard manner.
