Supported Events

Table 1 GaussDB

Source	Namespace	Name	ID	Severity	Description	Handling Suggestion	Impact
GaussDB	SYS.GAUSSDBV5	Process status alarm	ProcessStatusAlarm	Major	Key GaussDB processes exit, including CMS/CMA, ETCD, GTM, CN, and DN processes.	Wait until the process is automatically recovered or a primary/standby failover is automatically performed. Check whether services are recovered. If no, contact SRE engineers.	If processes on primary nodes are faulty, services are interrupted and then rolled back. If processes on standby nodes are faulty, services are not affected.
		Component status alarm	ComponentStatusAlarm	Major	Key GaussDB components do not respond, including CMA, ETCD, GTM, CN, and DN components.	Wait until the process is automatically recovered or a primary/standby failover is automatically performed. Check whether services are recovered. If no, contact SRE engineers.	If processes on primary nodes do not respond, neither do the services. If processes on standby nodes are faulty, services are not affected.
		Cluster status alarm	ClusterStatusAlarm	Major	The cluster is abnormal, including the following faults: The cluster is read-only. The majority of ETCD members are faulty. The cluster resources are unevenly distributed.	Contact SRE engineers.	If the cluster status is read-only, only read requests are processed. If the majority of ETCD members are faulty, the cluster is unavailable. If resources are unevenly distributed, the instance performance and reliability deteriorate.
		Hardware resource alarm	HardwareResourceAlarm	Major	A major hardware fault occurs in the instance, such as disk damage or GTM network fault.	Contact SRE engineers.	Some or all services are affected.
		Status transition alarm	StateTransitionAlarm	Major	The following events occur in the instance: DN build attempt, DN build failure, forcible DN promotion, primary/standby DN switchover/failover, or primary/standby GTM switchover/failover.	Wait until the fault is automatically rectified and check whether services are recovered. If no, contact SRE engineers.	Some services are interrupted.
		Other abnormal alarm	OtherAbnormalAlarm	Major	Disk usage threshold alarm	Monitor workload changes and scale up storage as needed.	If the used space exceeds the threshold, storage cannot be scaled up.
		Instance running status abnormal	TaurusInstanceRunningStatusAbnormal	Major	This event is a key alarm event and is reported when an instance is faulty due to a disaster or a server failure.	Submit a service ticket.	The database service may be unavailable.
		Instance running status recovered	TaurusInstanceRunningStatusRecovered	Major	GaussDB provides an HA tool to automatically or manually rectify the catastrophic fault. After the fault is rectified, this event is reported.	No further action is required.	None
		Node status abnormal	TaurusNodeRunningStatusAbnormal	Major	This event is a key alarm event and is reported when a database node is faulty due to a disaster or a server failure.	Check whether the database service is available and submit a service ticket.	The database service may be unavailable.
		Node recovered	TaurusNodeRunningStatusRecovered	Major	GaussDB provides an HA tool to automatically or manually rectify the catastrophic fault. After the fault is rectified, this event is reported.	No further action is required.	None
		Instance creation failure	GaussDBV5CreateInstanceFailed	Major	Instances fail to be created because the quota is insufficient or underlying resources are exhausted.	Release the instances that are no longer used and try to provision new instances again, or submit a service ticket to adjust the quota.	Instances fail to be created.
		Node adding failure	GaussDBV5ExpandClusterFailed	Major	The underlying resources are insufficient.	Submit a service ticket to ask O&M personnel to coordinate resources, delete the node that failed to be added and add a new one.	None
		Storage scale-up failure	GaussDBV5EnlargeVolumeFailed	Major	The underlying resources are insufficient.	Submit a service ticket. The O&M personnel will coordinate resources in the background and then you scale up the storage space again.	Services may be interrupted.
		Reboot failure	GaussDBV5RestartInstanceFailed	Major	The network is abnormal.	Retry the reboot operation or submit a service ticket to the O&M personnel.	The database service may be unavailable.
		Full backup failure	GaussDBV5FullBackupFailed	Major	The backup files fail to be exported or uploaded.	Submit a service ticket to O&M personnel.	Data cannot be backed up.
		Differential backup failure	GaussDBV5DifferentialBackupFailed	Major	The backup files fail to be exported or uploaded.	Submit a service ticket to O&M personnel.	Data cannot be backed up.
		Backup deletion failure	GaussDBV5DeleteBackupFailed	Major	Backup files fail to be cleared.	Submit a service ticket to O&M personnel.	There may be residual OBS files.
		EIP binding failure	GaussDBV5BindEIPFailed	Major	The EIP has been used or EIP resources are insufficient.	Submit a service ticket to O&M personnel.	The instance cannot be accessed from the Internet.
		EIP unbinding failure	GaussDBV5UnbindEIPFailed	Major	The network or the EIP service is faulty.	Unbind the IP address again or submit a service ticket to the O&M personnel.	Residual IP resources may be generated.
		Parameter template application failure	GaussDBV5ApplyParamFailed	Major	Changing a parameter group times out.	Change the parameter group again.	None
		Parameter modification failure	GaussDBV5UpdateInstanceParamGroupFailed	Major	Changing a parameter group times out.	Change the parameter group again.	None
		Backup and restoration failure	GaussDBV5RestoreFromBcakupFailed	Major	The underlying resources are insufficient or backup files fail to be downloaded.	Submit a service ticket.	The database service may be unavailable during the restoration failure.
		Hot patch installation failure	GaussDBV5UpgradeHotfixFailed	Major	Generally, this fault is caused by an error reported during kernel upgrade.	View the error information about the workflow and redo or skip the job.	None
