The PD_PLTR record stores performance data indicating the number of pages moved by tier relocations for Dynamic Provisioning pools that have tier management enabled. This is a multi-instance record.
- Information about Copy-on-Write Snapshot pools, Thin Image pools, and Dynamic Provisioning pools that do not have tier management enabled is not collected.
- RAID Agent does not collect information about a blocked Dynamic Provisioning pool except when the pool is blocked because of its usage rate reaching 100%.
- Performance data is saved whenever tier relocation information for the storage system is updated. If you collect performance data immediately after RAID Agent starts, the data that was collected the last time might be saved again.
- Information about Dynamic Provisioning pools is not collected if tier relocation 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.
