You can obtain performance and capacity information about each resource that VSP One SDS Block is collecting.
The performance information the user can obtain is divided into two types: low-temporal-resolution (hereinafter, low-resolution) information that is collected at 1-minute intervals and high-temporal-resolution (hereinafter, high-resolution) information that is collected at 5-second intervals. Low-resolution information refers to the information obtained from archival records. High-resolution information refers to the latest information. (Some information is only available as low-resolution information.)
Low-resolution information is retained for up to two days. Low-resolution information that exceeds the maximum retention days is deleted in the oldest order.
When a problem occurs in the storage system, obtain and utilize high-resolution information about the specific faulty resource for troubleshooting.
Regularly obtain and utilize low-resolution information to verify whether the system is running normally and any abnormality has occurred.
