REDO LOG GC STATUS	the redo log status	`pnodeRun(getRedoLogGCStat)`
TRANSACTION STATUS	the transaction status	`pnodeRun(getTransactionStatus)`
TABLETS META	the metadata of the 100 chunks in the cluster with the most rows	`select top 100 * from pnodeRun(getTabl etsMeta{"%","%",false,-1}) order by rowNum desc`
