Events Supported by Event Monitoring

Note

Events in Event Monitoring come from operations on cloud service resources and are not collected by the Agent in Server Monitoring.

Table 1 Elastic Cloud Server (ECS)

Event Source	Event Name	Event ID	Event Severity	Description	Solution	Impact
ECS	Delete ECS	deleteServer	Major	The ECS was deleted on the management console. by calling APIs.	Check whether the deletion was performed intentionally by a user.	Services are interrupted.
	Reboot ECS	rebootServer	Minor	The ECS was restarted on the management console. by calling APIs.	Check whether the restart was performed intentionally by a user. Deploy service applications in HA mode. After the ECS starts up, check whether services recover.	Services are interrupted.
	Resize ECS	resizeServer	Minor	The ECS was resized on the management console. by calling APIs.	Check whether the operation was performed by a user. Deploy service applications in HA mode. After the ECS is resized, check whether services have recovered.	Services are interrupted.
	Restart triggered due to hardware fault	startAutoRecovery	Major	ECSs on a faulty host would be automatically migrated to another properly-running host. During the migration, the ECSs was restarted.	Wait for the event to end and check whether services are affected.	Services may be interrupted.
	Restart completed due to hardware failure	endAutoRecovery	Major	The ECS was restored to be normal after the automatic migration.	This event indicates that the ECS has recovered and been working properly.	None
	Auto recovery timeout (being processed on the backend)	faultAutoRecovery	Major	Migrating the ECS to a normal host timed out.	Migrate services to other ECSs.	Services are interrupted.
	Improper ECS running	vmIsRunningImproperly	Major	The ECS was faulty or the ECS NIC was abnormal.	Deploy service applications in HA mode. After the fault is rectified, check whether services recover.	Services are interrupted.
	Improper ECS running recovered	vmIsRunningImproperlyRecovery	Major	The ECS was restored to the normal status.	Wait for the ECS status to become normal and check whether services are affected.	None
	VM faults caused by host process exceptions	VMFaultsByHostProcessExceptions	Critical	The processes of the host accommodating the ECS were abnormal.	Contact O&M personnel.	The ECS is faulty.
	Restarted GuestOS	RestartGuestOS	Minor	The guest OS was restarted.	Contact O&M personnel.	Services may be interrupted.

Note

Once a physical host running ECSs breaks down, the ECSs are automatically migrated to a functional physical host. During the migration, the ECSs will be restarted.

Table 2 Advanced Anti-DDoS (AAD)

Event Source	Event Name	Event ID	Event Severity	Description	Solution	Impact
AAD	DDoS Attack Events	ddosAttackEvents	Major	A DDoS attack occurs in the AAD protected lines.	Judge the impact on services based on the attack traffic and attack type.

The actual blackhole duration is related to the blackhole triggering times and peak attack traffic on the current day. The maximum duration is 24 hours. If you need to permit access before a blackhole becomes ineffective, contact technical support.	Services may be interrupted.
	Cancel Blackhole	cancelBlackHole	Informational	The customer's AAD instance recovers from the black hole state.	This is only a prompt and no action is required.	Customer services recover.

Table 4 Relational Database Service (RDS) — resource exception

Event Source	Event Name	Event ID	Event Severity	Description	Solution	Impact
RDS	Full backup failure	fullBackupFailed	Major	A single full backup failure does not affect the files that have been successfully backed up, but prolong the incremental backup time during the point-in-time restore (PITR).	Create a manual backup again.	Backup failed.
	Primary/standby switchover or failover	PrimaryStandbySwitched	Major	This event is reported when a primary/standby switchover or a failover is triggered.	After the switchover or failover is complete, check whether workloads are restored. If workloads are not restored, contact SRE engineers. Ignore the event if you have performed a switchover. If the failover is triggered by a node fault, contact the SRE engineers.	Downtime occurs during the switchover.
	Replication status abnormal	abnormalReplicationStatus	Major	The possible causes are as follows: The replication delay between the primary instance and the standby instance or a read replica is too long, which usually occurs when a large amount of data is being written to databases or a large transaction is being processed. During peak hours, data may be blocked. The network between the primary instance and the standby instance or a read replica is disconnected.	Submit a service ticket.	Your applications are not affected because this event does not interrupt data read and write.
	Replication status recovered	replicationStatusRecovered	Major	The replication delay between the primary and standby instances is within the normal range, or the network connection between them has restored.	No action is required.	None
	DB instance faulty	faultyDBInstance	Major	A single or primary DB instance was faulty due to a disaster or a server failure.	Check whether an automated backup policy has been configured for the DB instance and submit a service ticket.	The database service may be unavailable.
	DB instance recovered	DBInstanceRecovered	Major	RDS rebuilds the standby DB instance with its high availability. After the instance is rebuilt, this event will be reported.	No action is required.	None
	Failure of changing single DB instance to primary/standby	singleToHaFailed	Major	A fault occurs when RDS is creating the standby DB instance or configuring replication between the primary and standby DB instances. The fault may occur because resources are insufficient in the data center where the standby DB instance is located.	Submit a service ticket.	Your applications are not affected because this event does not interrupt data read and write of the DB instance.
	Database process restarted	DatabaseProcessRestarted	Major	The database process is stopped due to insufficient memory or high load.	Log in to the Cloud Eye console. Check whether the memory usage increases sharply, the CPU usage is too high for a long time, or the storage space is insufficient. You can increase the CPU and memory specifications or optimize the service logic.	When the process exits abnormally, workloads are interrupted. In this case, RDS automatically restarts the database process and attempts to recover the workloads.
	Instance storage full	instanceDiskFull	Major	Generally, the cause is that the data space usage is too high.	Scale up the instance.	The DB instance becomes read-only because the storage space is full, and data cannot be written to the database.
	Instance storage full recovered	instanceDiskFullRecovered	Major	The instance disk is recovered.	No action is required.	Cancel the read-only state of the instance and resume write operations.
	Read replica promotion failure	activeStandBySwitchFailed	Major	The read replica fails to be promoted to the primary DB instance due to network or server failures. The original primary DB instance takes over workloads quickly.	Submit a service ticket.	The read replica fails to be promoted to the primary DB instance.
