This topic describes the system events of Object Storage Service (OSS).
Note For information about OSS throttling events, see Use CloudMonitor to monitor OSS throttling information in real time.
| Event | Description | Status | Level | Cause |
|---|---|---|---|---|
| BucketEgressBandwidth | The downstream bandwidth that is used by a bucket exceeds the report threshold. | Normal | Info | This event is triggered if the total downstream bandwidth that is used by the current bucket exceeds the report threshold. |
| BucketEgressBandwidthThresholdExceeded | The downstream bandwidth that is used by a bucket exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total downstream bandwidth that is used by the current bucket exceeds the throttling threshold. |
| BucketIngressBandwidth | The upstream bandwidth that is used by a bucket exceeds the report threshold. | Normal | Info | This event is triggered if the total upstream bandwidth that is used by the current bucket exceeds the report threshold. |
| BucketIngressBandwidthThresholdExceeded | The upstream bandwidth that is used by a bucket exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total upstream bandwidth that is used by the current bucket exceeds the throttling threshold. |
| BucketImageCpuThresholdExceeded | The number of CPU cores that are used by a bucket to process Image Processing (IMG) requests exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total number of CPU cores that are used by the current bucket to process IMG requests exceeds the throttling threshold. |
| BucketMirrorIngressBandwidthThresholdExceeded | The bandwidth that is used by a bucket to send mirroring-based back-to-origin requests exceeds the throttling threshold. | Normal | Warn | This event is triggered if the bandwidth that is used by the current bucket to send mirroring-based back-to-origin requests exceeds the throttling threshold. |
| BucketMirrorQpsThresholdExceeded | The number of requests that are sent by a bucket per second to implement mirroring-based back-to-origin exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total number of requests that are sent by the current bucket per second to implement mirroring-based back-to-origin exceeds the throttling threshold. |
| BucketQpsThresholdExceeded | The number of requests that are received by a bucket per second exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total number of requests that are received by the current bucket per second exceeds the throttling threshold. |
| UserEgressBandwidth | The downstream bandwidth of a user exceeds the report threshold. | Normal | Info | This event is triggered if the total downstream bandwidth that is used by all buckets of the current user exceeds the report threshold. |
| UserEgressBandwidthThresholdExceeded | The downstream bandwidth of a user exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total downstream bandwidth that is used by all buckets of the current user exceeds the throttling threshold. |
| UserIngressBandwidth | The upstream bandwidth of a user exceeds the report threshold. | Normal | Info | This event is triggered if the total upstream bandwidth that is used by all buckets of the current user exceeds the report threshold. |
| UserIngressBandwidthThresholdExceeded | The upstream bandwidth of a user exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total upstream bandwidth that is used by all buckets of the current user exceeds the throttling threshold. |
| UserImageCpuThresholdExceeded | The number of CPU cores that are used to process IMG requests for a user exceeds the throttling threshold. | Normal | Warn | This event is triggered if the number of CPU cores that are used by all buckets of the current user to process IMG requests exceeds the throttling threshold. |
| UserMirrorIngressBandwidthThresholdExceeded | The traffic that is consumed to send mirroring-based back-to-origin requests for a user exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total traffic that is consumed by all buckets of the current user to send mirroring-based back-to-origin requests exceeds the throttling threshold. |
| UserMirrorQpsThresholdExceeded | The number of requests that are sent per second to implement mirroring-based back-to-origin for a user exceeds the throttling threshold. | Normal | Warn | This event is triggered if the total number of requests that are sent by all buckets of the current user per second to implement mirroring-based back-to-origin exceeds the throttling threshold. |
| UserQpsThresholdExceeded | The number of requests that are received per second for a user exceeds the throttling threshold. | Normal | Warn | The total number of requests that are received by all buckets of the current user per second exceeds the throttling threshold. |
