The component in this framework is available in all Talend products.

## Basic settings

| Use input connection name as label | Select this check box to reuse the name given to the input main<br>row flow as label in the logged data. |
| --- | --- |
| Mode | Select the type of values for the data measured: Absolute: the actual number of rows is<br>logged<br><br><br>Relative: a ratio (%) of the number<br>of rows is logged. When this option is selected, a Connections List shows to let you select<br>a reference connection. |
| Thresholds | Adds a threshold to watch proportions in volumes measured. you can<br>decide that the normal flow has to be between low and top end of a<br>row number range, and if the flow is under this low end, there is a<br>bottleneck. |

## Global Variables

| Global Variables | ERROR\_MESSAGE: the error message generated by the component when an<br>error occurs. This is an After variable and it returns a string. This variable functions<br>only if the Die on error check box<br>is cleared, if the component has this check<br>box.<br><br>A Flow variable functions during the execution of a component<br>while an After variable functions after the execution of the component.<br><br>To fill up a field or expression with a<br>variable, press Ctrl + Space to<br>access the variable list and choose the variable to use from it.<br><br>For further information about variables, see *Talend Studio*<br>*User Guide*. |
