The PD_PLF record stores performance data indicating the page I/O processing status of the Dynamic Provisioning pool.
- Information about Copy-on-Write Snapshot pools, Thin Image pools, and Dynamic Provisioning pools that do not have tier management enabled is not collected.
- If the Dynamic Provisioning pool is blocked, RAID Agent does not collect information about the pool. However, if the Dynamic Provisioning pool is blocked because the usage rate of the pool capacity is 100%, RAID Agent collects information about the pool.
- Performance data is saved whenever monitoring information for the storage system is updated. If you collect records immediately after RAID Agent starts, the system might collect the same data it collected earlier.
- Information about Dynamic Provisioning pools is not collected if monitoring information has never been collected by the storage system.
- If RAID Agent is collecting records when the storage system is aggregating monitoring information, the collecting of records is canceled, and the KAVF18514-W message is output to the common log.
- If you stop and then restart the RAID Agent, monitoring information that covers the same time period might be stored twice.
