This topic introduces the flow control event metrics available for TOS and provides an example of event notifications.
Supported metrics
tip
Event metrics are divided into two categories: resource and reporting thresholds.
- Resource threshold: The maximum amount of TOS resources available to the current account. For more information on the default maximum usable resources, see Limits.
- Reporting threshold = Resource threshold × 0.8.
Event description | Event type | Impact | How to fix it |
Account upload bandwidth exceeds the resource threshold | AccountUploadBandwidthThresholdExceeded | Increased latency for put requests | Reduce the concurrency of put requests to a reasonable level |
Account download bandwidth exceeds the resource threshold | AccountDownloadBandwidthThresholdExceeded | Increased latency for get requests | Reduce the concurrency of get requests to a reasonable level |
Account put request QPS exceeds the resource threshold | AccountPutQPSThresholdExceeded | Some put requests are rejected with a 429 status code | Reduce the number of put requests per second to a reasonable amount |
Account get request QPS exceeds the resource threshold | AccountGetQPSThresholdExceeded | Some get requests are rejected with a 429 status code | Reduce the number of get requests per second to a reasonable amount |
Account list request QPS exceeds the resource threshold | AccountListQPSThresholdExceeded | Some list requests are rejected with a 429 status code | Reduce the number of list requests per second to a reasonable amount |
Bucket upload bandwidth exceeds the resource threshold | BucketUploadBandwidthThresholdExceeded | Increased latency for put requests | Reduce the concurrency of put requests to a reasonable level |
Bucket download bandwidth exceeds the resource threshold | BucketDownloadBandwidthThresholdExceeded | Increased latency for get requests | Reduce the concurrency of get requests to a reasonable level |
Bucket put request QPS exceeds the resource threshold | BucketPutQPSThresholdExceeded | Some put requests are rejected with a 429 status code | Reduce the number of put requests per second to a reasonable amount |
Bucket get request QPS exceeds the resource threshold | BucketGetQPSThresholdExceeded | Some get requests are rejected with a 429 status code | Reduce the number of get requests per second to a reasonable amount |
Bucket list request QPS exceeds the resource threshold | BucketListQPSThresholdExceeded | Some list requests are rejected with a 429 status code | Reduce the number of list requests per second to a reasonable amount |
Account upload bandwidth under QoS policies exceeds the resource threshold | AccountQosPolicyUploadBandwidthThresholdExceeded | Increased latency for put requests | Reduce the concurrency of put requests to a reasonable level |
Account download bandwidth under QoS policies exceeds the resource threshold | AccountQosPolicyDownloadBandwidthThresholdExceeded | Increased latency for get requests | Reduce the concurrency of get requests to a reasonable level |
Account put request QPS under QoS policies exceeds the resource threshold | AccountQosPolicyPutQPSThresholdExceeded | Some put requests are rejected with a 429 status code | Reduce the number of put requests per second to a reasonable amount |
Account get request QPS under QoS policies exceeds the resource threshold | AccountQosPolicyGetQPSThresholdExceeded | Some get requests are rejected with a 429 status code | Reduce the number of get requests per second to a reasonable amount |
Account list request QPS under QoS policies exceeds the resource threshold | AccountQosPolicyListQPSThresholdExceeded | Some list requests are rejected with a 429 status code | Reduce the number of list requests per second to a reasonable amount |
Account upload bandwidth exceeds the reporting threshold | AccountUploadBandwidth | None | None |
Account download bandwidth exceeds the reporting threshold | AccountDownloadBandwidth | None | None |
Account put request QPS exceeds the reporting threshold | AccountPutQPS | None | None |
Account get request QPS exceeds the reporting threshold | AccountGetQPS | None | None |

Bucket list request QPS exceeds the reporting threshold | BucketListQPS | None | None |
Account upload bandwidth under QoS policies exceeds the reporting threshold | AccountQosPolicyUploadBandwidth | None | None |
Account download bandwidth under QoS policies exceeds the reporting threshold | AccountQosPolicyDownloadBandwidth | None | None |
Account put request QPS under QoS policies exceeds the reporting threshold | AccountQosPolicyPutQPS | None | None |
Account get request QPS under QoS policies exceeds the reporting threshold | AccountQosPolicyGetQPS | None | None |
Account list request QPS under QoS policies exceeds the reporting threshold | AccountQosPolicyListQPS | None | None |
Event notification example
Once an event rule is set up for flow control purposes, the system will send notifications through your chosen channel whenever a relevant event occurs or the reporting threshold is met. Below is an example of an event notification.
{
"data": {
"AccountId": "214748****",
"BucketName":"bucketname",
"PercentThresholdLevel": 100,
"QosPolicySid": "qospolicy-c862",
"TrafficSource": "net_all"
}
}
The fields are described below:
Field | Description |
AccountId | Specifies the ID of the Volcano Engine account being reported. |
BucketName | Specifies the name of the bucket being reported. tip The BucketName field only appears in event notifications for bucket flow control events. |
PercentThresholdLevel | Specifies the traffic value triggering the event notification as a percentage of the resource threshold. |
QosPolicySid | Specifies the name of the QoS policy. tip The QosPolicySid field appears in event notifications only when the events are governed by a QoS policies. |
TrafficSource | Specifies the source of the traffic that triggers the flow control event notification. The values are explained below:
