The TIBCO StreamBase^® Runtime Administrator offers access a variety of statistics via the statistics tab of the Node panel. Application, node, and system level reports are available and are selected via the pull down menu:

Some of these statistics are collected automatically by the runtime. For these, the Enable and Disable buttons will not be greyed out and not clickable. Clicking the Display button will show the current values.

Other statistics need to be enabled in order to activate data collection. Generally this is because the collection of these statistics imposes some performance, memory usage, or disk usage penalty upon the system. For these, the Enable button must be clicked, and the desired amount of time should be waited before clicking the Display button to show the collected statistics. It is also good practice to disable the statistic collection, by pressing the Disable button, before displaying the report. This restores the system to its previous performance level, and also keeps the reporting itself from showing up in the measurement.

Some statistics support clearing. Those statistics may be cleared at any time by pressing the Clear button. For statistics that do not support clearing the Clear button will be greyed out and not clickable.

After a report is displayed, it may be printed by clicking the Print button.
