> Data storage metrics have unclear descriptions. They need to be improved.
> ||Metric||Description||Comment||
> |*WalLoggingRate*|Average number of WAL records per second written during the last time interval.|The "time interval" part is unclear. Which time interval?|
> |*WalFsyncTimeDuration*|Total duration of fsync|Why not just *WalFsyncDuration*?
> The description could be more verbose.|
> |*WalFsyncTimeNum*|Total count of fsync|Why not just *WalFsyncNum*? The description could be more verbose|
> |*WalBuffPollSpinsRate*|WAL buffer poll spins number over the last time interval. |Over which time interval?|
> |*LastCheckpointMarkDuration*|Duration of the checkpoint lock wait in milliseconds |The description doesn't match the name.|
> |*CheckpointTotalTime*|Total duration of checkpoint|Is it the duration of the last checkpoint or all checkpoints from the beginning?|
> |*StorageSize*|Storage space allocated, in bytes.|It's unclear which storage this is about. Is disk included, or is it just about memory?|
> |*WalTotalSize*|Total size in bytes for storage wal files.|WAL should be capital. The grammar|
