Cluster O&M

Alarm Management

MRS can monitor big data clusters in real time and identify system health status based on alarms and events. In addition, MRS allows you to customize monitoring and alarm thresholds to focus on the health status of each metric. When monitoring data reaches the alarm threshold, the system triggers an alarm.

MRS can also interconnect with the message service system of the Simple Message Notification (SMN) service to push alarm information to users by SMS message or email. For details, see Message Notification.

O&M Support

Cluster resources provided by MRS belong to users. Generally, when O&M personnel's support is required for troubleshooting of a cluster, O&M personnel cannot directly access the cluster. To better serve customers, MRS provides the following two methods to improve communication efficiency during fault locating:

• Log sharing: You can initiate log sharing on the MRS management console to share a specified log scope with O&M personnel, so that O&M personnel can locate faults without accessing the cluster.
• O&M authorization: If a problem occurs when you use an MRS cluster, you can initiate O&M authorization on the MRS management console. O&M personnel can help you quickly locate the problem, and you can revoke the authorization at any time.

Health Check

MRS provides automatic inspection on system running environments for you to check and audit system running health status in one click, ensuring proper system running and lowering system operation and maintenance costs. After viewing inspection results, you can export reports for archiving and fault analysis.
