Component family

Logs & Errors

Function

Counts the number of rows processed in the defined flow.

Purpose

The number of rows is then meant to be caught by the tFlowMeterCatcher for logging
purpose.

Basic settings

Use input connection name as label

Select this check box to reuse the name given to the input main
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
logged

Relative: a ratio (%) of the number
of rows is logged. When this option is selected, a Connections List shows to let you select
a reference connection.

Thresholds

Adds a threshold to watch proportions in volumes measured. you can
decide that the normal flow has to be between low and top end of a
row number range, and if the flow is under this low end, there is a
bottleneck.

Global Variables

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio
User Guide.

Usage

Cannot be used as a start component as it requires an input flow
to operate.
