Bytes Downloaded

The metric specifies the response bytes of all download requests made to all buckets in a region, including bytes in HTTP bodies. Bytes downloaded is measured in the unit of byte. The following figure shows the monitoring graph of the metric.

Bytes Uploaded

The metric specifies the bytes in the message bodies of all upload requests made to all buckets in a region, including bytes in HTTP bodies. Bytes uploaded is measured in the unit of byte. The following figure shows the metric graph of bytes uploaded for a longer time. In the figure, the period is set to June 1, 2018 to July 12, 2018; for the rollup group, the period is 4 hours and the method is Sum; the unit is MB.

You can configure a period of the metric, its rollup data and unit to be displayed in a monitoring graph. The operation is the same as that of Bytes Downloaded.

GET Requests

This metric specifies the number of GET, HEAD, or OPTIONS requests made to all buckets and objects in the buckets of a region. It is measured in count. The following figure shows the metric graph of GET requests for a longer time. In the figure, the period is set to last 3 hours, and for the rollup group, the period is 20 minutes and the method is Variance.

You can configure a period of the metric and its rollup data to be displayed. The operation is the same as that of Bytes Downloaded.

First Byte Download Delay

This metric specifies the average time that a system receives a GET, HEAD, or OPTIONS request to the time that the system starts to respond to the request in a measurement period. The following figure shows the metric graph of the first byte download delay. In the figure last seven days, the period is set to last 7 days, and for the rollup group, the period is 1 hour and the method is Average.

PUT requests

This metric specifies the number of PUT, POST, or DELETE requests made to all buckets and objects in the buckets of a region. It is measured in count. The following figure shows the metric graph of PUT requests for a longer time. In the figure, the period is set to last 30 days, and for the rollup group, the period is 4 hours and the method is Sum.

4xx Errors

This metric specifies the number of requests whose error code is 4xx returned by the server. It is measured in count. The following figure shows the metric graph of 4xx errors for a longer time. In the figure, the period is set to last 7 days, and for the rollup group, the period is 1 hour and the method is Sum.

5xx Errors

This metric specifies the number of requests whose error code is 5xx returned by the server. It is measured in count. The following figure shows the metric graph of 5xx errors for a longer time. In the figure, the period is set to Last 30 days, and for the rollup group, the period is 24 hours and the method is Average.
