There may be slight overhead incurred while running platform statistics, however the overhead is insignificant. No disk space is consumed by enabling platform statistics, since no log files are created. As with Domino statistics, disk space is used only if you log platform statistics to the log file or to the Monitoring Results database (STATREP.NSF). The amount of disk space used depends on the frequency of capture.
By default, the Statistic Collector task continuously gathers these statistics:
When collecting statistics from a partitioned server, Domino collects platform statistics that pertain to the system as a whole, not to an individual partition. For example, memory use or CPU use statistics are the same value on a partitioned and non-partitioned server. The only statistics that are specific to a partition are those that reflect tasks, such process statistics, where one partition might run 10 tasks, while another partition runs 15 tasks.
Confirming platform statistics metrics using other performance monitoring tools
Because of the differences in sampling intervals, you cannot use native monitoring tools to confirm platform statistics. There will be discrepancies between platform statistics and those obtained using Perfmon (for Windows NT or Windows 2000) or a system command, such as this UNIX command:
iostat /vmstat/ netstat
Platform statistics for Domino for Linux
Domino for Linux depends on the iostat command to provide information for platform statistics monitoring, for example, the Logical Disk statistics. If iostat is not available to Domino for Linux, platform statistics are not available. Install the sysstat package, containing iostat, to enable to collection of statistics for Domino for Linux.
