New page

= Overview =

KeyStats represent an amazing tool for being able to generate wallboards and other real time information displays. The generation of the key statistics that it uses can take some time to render. Where an environment has lots of areas displaying the same key stat output, this means an excessive amount of calculations are done. KeyStat mirroring is an integrated caching engine which reduces processing overhead.

= The process =

* Turn mirroring on (detailed below)
* The first time the page draws, a snapshot is taken and stored with the date and time.
* Another machine requests the keystat
** Is mirroring turned on? Yes
** Is there a snapshot? Yes
** Is the snapshot recent enough? Yes
** In this case, the page is not drawn, the snapshot instead is drawn

Eventually the snapshot timeout will be reached and the page will redraw but this means, not every machine is redrawing every time the request is made.

= Turning on mirroring =

Mirroring is seamless. It can be easily turned on and off and the settings experimented with.

''Main Menu > KeyStats > KeyStat Administration > KeyStat - Workbook - Edit > Choose your Workbook > Scroll to the bottom.''

* Use Mirroring : True | False
* Mirror Refresh Rate : Time in seconds

Use Mirroring as true is how the engine is turned on.

The mirror refresh rate is not to be confused with the page refresh rate. This is the timeout window for a snapshot. i.e. your refresh your page every 20 seconds. your mirror refresh rate is 60 seconds. That means at 0 seconds (the first time the page loads) the keystat draws, at 20 and 40 seconds, the Mirror will be drawn.

If you edit any settings of a KeyStat tab the time and snapshot will be emptied and redraw on next keystat tab load.
