onstat -g grp ER Grouper Statistics

The onstat -g grp command displays Grouper Statistics; the grouper evaluates the log records, rebuilds the individual log records into the original transaction, packages the transaction, and queues the transaction for transmission. The onstat -g grp command is used primarily as a debugging tool.

The command can take the following modifiers

ModifierAction
APrints all the information printed by the G, T, P, E, R, and S modifiers
EPrints grouper evaluator statistics
ExPrints grouper evaluator statistics, expands user-defined routine (UDR) environments
GPrints grouper general statistics
LPrints grouper global list
LxPrints grouper global list, expands open transactions
MPrints grouper compression statistics
MzClears grouper compression statistics
PPrints grouper table partition statistics
pagerPrints grouper paging statistics
RPrints grouper replicate statistics
SPrints grouper serial list head (The serial list head is the first transaction in the list, that is, the next transaction that will be placed in the send queue.)
SlPrints grouper serial list (The serial list is the list of transactions, in chronological order.)
SxPrints grouper serial list, expands open transactions
TPrints grouper transaction statistics
UDRPrints summary information about any UDR invocations by the grouper threads
UDRxPrints expanded information (including a summary of error information) about any UDR invocations by the grouper threads The Procid column lists the UDR procedure ID.
