Configure Advanced Global settings

In the Global settings pane, you have the option to click the Show advanced global configuration link to display a list of configuration options to be applied to all interfaces in the system. Use the following procedure to set these options:

1. Buffering: Select On from the drop-down menu to enable buffering.

2. PI API buffering: Select "On" from the drop-down menu to allow PI API connections, or "Off". Observe the caution note in PI ICU. If you change the PI API buffering value, you must restart the PI Buffer Subsystem and its dependent interfaces.

3. AF SDK buffering: Select Buffer if possible (default), Always Buffer, or Do Not Buffer from the drop-down menu. Note that AF SDK applications can override this setting for some or all features.

4. PI SDK buffering: Select "On" from the drop-down menu to enable PI SDK connections, or "Off".

5. Queue capacity sample period: In the second(s) field, enter a value (for example, 600) to determine the buffer queue capacity. This is based on the average bytes written to buffer queue(s) over this sampling period. This may be adjusted to ensure that data is written to the buffering queue at a consistent rate.

6. Queue capacity warning trigger: In the hour(s) field, enter the value. A warning is then sent when the remaining queue capacity reaches this number of hours.

7. Queue capacity error trigger: In the hour(s) field, enter the value. An error is shown when the remaining queue capacity reaches this number of hours.

8. Registration check interval: In the second(s) field, enter the value specifying the intervals at which PI Buffer Subsystem checks the PI SDK and AF SDK client connections. It drops any that are no longer active, or no longer associated with buffered data.

9. Flush cycle: In the second(s) field, enter the value specifying the intervals at which cached snapshot records are written to disc and the cache is cleared.

10. Pause rate: In the millisecond(s) field, enter the value specifying the rate at which data is processed to the API buffer.

11. Click Save.
