Server.Load metrics and messaging statistics
As you run a test, you can view various script metrics and server statistic metrics and optionally store the test output in a separate file. Server statistic metrics are generated by the Domino® server. Script metrics correspond to Server.Load command names and display the performance of particular commands. For example, if you select the Add metric, the Metrics window displays the results of the Add command.

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

Table 1. 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

Table 2. 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.

Table 3. 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.

Table 4. 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 are automatically provided and collected for every test.

Table 5. Per Minute Thread statistics

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.
