System statistics can be edited and output to a system journal file by entering the dcstats command. When the dcstats command executes, information is output to the system journal file continuously at the interval specified in the -m option. The edited output information includes for each interval the number of event occurrences, the average value, the maximum value, and the minimum value, depending on the type of statistics specified with the -k option. It is also possible to specify a server name in order to output this information for the specified server.

Output of system statistics can be terminated by entering the dcstats command with the -r option specified. If the -r option is not specified in the dcstats command, output of system statistics continues until OpenTP1 terminates.

To change the type of system statistics or the interval specified in the dcstats command, the dcstats command must be reexecuted after executing the dcstats -r command.

The specification of the dcstats command is not inherited when OpenTP1 is restarted. To output system statistics after OpenTP1 has been restarted, the dcstats command must be reentered.

Note that system statistics can be edited and output from shared memory to the standard output in real time. To do so, execute the dcreport command.

For details about the items to be edited in system statistics, see Table E-2.
