Events Supported by Event Monitoring

Table 1 Resource exception events

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 of disks and quota size. 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 prolongs the incremental backup restoration time during the point-in-time recovery (PITR).

Create a manual backup again.

Backup failed.

Primary/standby switchover 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 and standby instances is too long, which usually occurs when a large amount of data is written to databases or a large transaction is processed. During peak hours, data may be blocked.

The network between the primary and standby instances 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

This event is reported after an RDS single-node instance is recovered from a disaster or its physical machine is recovered, or when a primary/standby instance completes a failover.

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.

Downtime occurs. 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.
