MercMon Reference
TotalFatSramBlocks
returns the number of times the system received a “CHAINED” data block (i.e., the data
blocks are linked together)
TotalIrpsCancelled
returns the total number of cancelled requests in any queue
TotalMsgInQ
returns the number of requests in the Message In Queue, which are awaiting a reply from a
board
TotalMsgInQDone
returns the number of requests completed from the Message In Queue (i.e., requests completed
and sent to the application)
TotalMsgInSram
returns the total number of messages read from the SRAM
TotalMsgOutQDone
returns the number of requests completed from the Message Out Queue (these requests are
sent to the board and then moved to the Message In Queue, if expecting a reply, or completed
and sent to the application)
TotalMsgOutSram
returns the total number of messages written to the SRAM
TotalMsgOverruns
returns the total number of overruns for the orphan message queue (i.e., we had an orphan
message but there was no space in the Orphan Message Queue)
TotalMsgTimeouts
returns the total number of requests timed out while waiting to be written to the SRAM or
awaiting a reply from the SRAM (i.e. either in the Message In Q, Message Out Q or the Async
Message Q)
TotalOrphanMsgsv
returns the total number of Orphan Messages (i.e., messages which were read from the SRAM
but do not have any pending requests from the application)
TotalOrphanMsgVolume
returns the size (in bytes) of the messages present in the Orphan message queue at any given
time
TotalOrphanStrms
returns the total number of Orphan Streams in the Orphan Stream Table (i.e., data which was
read from the SRAM but did not have any pending Read Requests from the application)
TotalOrphanStrmMatches
returns the total number of streams matched in the Orphan Stream table
TotalOrphanStrmVolume
returns the size (in bytes) of the data present in the Orphan Stream table at any given time
TotalSramDataFull
returns a count of the number of times the HOST tried to write a stream (data) to the SRAM
but the SRAM was full
