Note If the server runs Microsoft® Windows®, you can also use the Windows Performance Monitor to measure performance.

Database statistics

Statistic	Description
Database.BufferPool.Reads	Number of database buffer pool reads.
Database.BufferPool.Used	Number of bytes allocated in the buffer control pool.
Database.BufferPool.Writes	Number of database buffer pool writes.
Database.DbCache.CurrentEntries	Number of entries in the database cache.
Database.DbCache.HighWaterMark	High water mark of the database cache.
Database.DbCache.Hits	Number of hits to the database cache.
Database.DbCache.InitialDbOpens	Number of database opens done by the database cache.
Database.NIFPool.Used	Number of database NIF pools

System statistics

Statistic	Description
Disc.c.Free (bytes)	Free disk space in bytes on drive 'n'. When disk space is low, compact, delete, or move databases. If problem persists, consider a larger hard disk.
Disc.c.Size (bytes)	Total size in bytes of drive 'n'.
Server.Trans.PerMinute	Number of transactions that took place in the last minute. Useful to monitor server use. If this number is consistently higher than that of other servers and performance is a problem, redistribute the server load to other servers.
Server.Users	Number of users with sessions open on the server. Useful to monitor overall server use. If this number is consistently higher than that of other servers and performance is a problem, redistribute the server load to other servers.

Mail statistics

Statistic	Description
Mail.AverageDeliverTime	Average delivery time of messages in seconds
Mail.AverageServerHops	Average number of server hops for a delivered message.
Mail.AverageSizeDelivered	Average size of message delivered, in K.
Mail.Dead	Number of undeliverable messages in MAIL.BOX. Useful for detecting problems with the Router. Check the server MAIL.BOX to view the dead mail messages and determine the problem.
Mail.Delivered	Number of messages received by the Router.
Mail.MaximumDeliverTime	Slowest delivery time of messages in seconds.
Mail.MinimumServerHops	Least number of server hops for a delivered message.
Mail.MaximumSizeDelivered	Largest message delivered, in K.
Mail.MinimumDeliverTime	Slowest delivery time of messages in seconds.
Mail.MaximumServerHops	Most number of server hops for a delivered message.
Mail.MinimumSizeDelivered	Smallest message delivered, in K.
Mail.TotalFailures	Total number of mail failures.
Mail.TotalRouted	Total number of recipients that mail has routed to since the server started.
Mail.Waiting	Number of outgoing mail messages waiting to be either delivered locally or transferred in MAIL.BOX. Useful for detecting problems with the mail Router.
Mail.WaitingRecipients	Number of recipients awaiting either local delivery or transfer.

Network statistics

Statistic	Description
NET.TCPIP.BytesReceived	Amount of data received from client to server using TCP/IP protocol.
NET.TCPIP.BytesSent	Amount of data sent from client to server using TCP/IP protocol.
NET.TCPIP.Sessions.Established.Incoming	Incoming sessions from client to server using TCP/IP protocol.

Per Minute Thread Statistics

These statistics are automatically provided and collected for every test.

Statistic	Description
Avg. Trans (Per Thread)	The average number of transactions per thread.
Min. Trans (Per Thread)	The minimum number of transactions per thread.
Max. Trans (Per Thread)	The maximum number of transactions per thread.
Total Trans (All Threads)	The total number of transactions per thread.
Running Threads	The total number of all threads currently running.
Agg. Replications	The aggregate number of replications that occurred.
Avg. Rsp. Time (ms)	The average NRPC response time. This is the average response across all threads and is the best overall value to track general server response curves. Note This value is not applicable to the Web Mail script
Running time (min)	The total running time.
