Events Supported by Event Monitoring

Table 1 Elastic Cloud Server (ECS)

Event Source	Event Name	Event ID	Event Severity	Description	Solution	Impact
ECS	Reboot ECS	rebootServer	Minor	The ECS was reboot on the management console. by calling APIs.	Check whether the reboot was performed intentionally by a user. Deploy service applications in HA mode. After the ECS starts up, check whether services recover.	Services are interrupted.
	Start auto recovery	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.
	Stop auto recovery	endAutoRecovery	Major	The ECS was recovered 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.
	Startup failure	faultPowerOn	Major	The ECS failed to start.	Start the ECS again. If the problem persists, contact O&M personnel.	The ECS cannot start.
	GPU link fault	GPULinkFault	Critical	The GPU of the host on which the ECS is located was faulty. recovering from a fault.	Deploy service applications in HA mode. After the GPU fault is rectified, check whether services are restored.	Services are interrupted.
	FPGA link fault	FPGALinkFault	Critical	The FPGA of the host on which the ECS is located was faulty. recovering from a fault.	Deploy service applications in HA mode. After the FPGA fault is rectified, check whether services are restored.	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
	Local disk failure	LocalDiskError	Major	Local disks used by the ECS were faulty.	Contact O&M personnel.	Local disks are unavailable.
	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.

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 Relational Database Service (RDS) — resource exception

Event Source	Event Name	Event ID	Event Severity	Description	Solution	Impact
RDS	DB instance creation failure	createInstanceFailed	Major	A DB instance fails to create because the number of disks is insufficient, the quota is insufficient, or underlying resources are exhausted.	Check the number and quota of disks. Release resources and create DB instances again.	DB instances cannot be created.
	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 failure	activeStandBySwitchFailed	Major	The standby DB instance does not take over workloads from the primary DB instance due to network or server failures. The original primary DB instance continues to provide workloads within a short time.	Check whether the connection between your application and the database is re-established.	None
	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.	The instance is restored and supports both read and write operations.
	Kafka connection failed	kafkaConnectionFailed	Major	The network is unstable or the Kafka server does not work properly.	Check your network connection and the Kafka server status.	Audit logs cannot be sent to the Kafka server.

Table 3 Relational Database Service (RDS) — operations

Event Source	Event Name	Event ID	Event Severity	Description
RDS	Reset administrator password	resetPassword	Major	The password of the database administrator is reset.
	Operate DB instance	instanceAction	Major	The storage space is scaled or the instance class is changed.
	Delete DB instance	deleteInstance	Minor	The DB instance is deleted.
	Modify backup policy	setBackupPolicy	Minor	The backup policy is modified.
	Modify parameter group	updateParameterGroup	Minor	The parameter group is modified.
	Delete parameter group	deleteParameterGroup	Minor	The parameter group is deleted.
	Reset parameter group	resetParameterGroup	Minor	The parameter group is reset.
	Change database port	changeInstancePort	Major	The database port is changed.
	Primary/standby switchover or failover	PrimaryStandbySwitched	Major	A switchover or failover is performed.
