The Object Storage Service (OSS) accelerator monitoring feature allows you to use the Bandwidth Usage, QPS Usage, Hit Rate, and Latency monitoring items to obtain the performance and status of OSS accelerators and improve cache hit rates. This helps ensure efficient and smooth data transfer.
How to increase the cache hit rate of an OSS accelerator
If the cache hit rate of an OSS accelerator is low, you can change the path of the accelerator to cache more data and expand the cache capacity. This prevents frequent data elimination and improves transfer performance.
Prerequisites
An OSS accelerator is created. For more information, see Create an OSS accelerator.
Monitoring items
Bandwidth Usage: the average outbound traffic in a specific period of time. This monitoring item indicates the overall data transfer rate.
QPS Usage: the average number of times that the accelerator is accessed in a specific period of time. This monitoring item indicates the frequency at which the accelerator is accessed.
Hit Rate: the percentage of the amount of data downloaded from the OSS accelerator cache in a specific period of time to the total amount of hit data downloaded in the same period of time. A higher value indicates more efficient cache utilization.
Latency: the value that is obtained by dividing the total amount of time consumed to transfer data that hits the OSS accelerator cache by the total number of hits in a specific period of time.
View the monitoring information
Go to the Buckets page and select the bucket that you want to manage.
In the left-side navigation tree, choose Bucket Settings > OSS Accelerator. On the OSS Accelerator page, click the Accelerator Monitoring tab.
Specify a time range and click Search to view the bandwidth usage, QPS usage, hit rate, and latency of the OSS accelerator. The following figure provides an example.
The following table describes the monitoring metrics of OSS accelerators.
