|
|
<p>A node to measure the flow message speed.</p>
|
||
|
|
<p><strong>Frequency</strong></p>
|
||
|
|
<p>The speed will be measured at the specified frequency.
|
||
|
|
E.g. frequency 'hour' means that (every second) the average speed of the previous hour will be calculated.</p>
|
||
|
|
<p><strong>Estimate speed</strong></p>
|
||
|
|
<p>In case estimation is disabled, the speed will be incorrect during the startup period.
|
||
|
|
E.g. when every second 1 message arrives, the calculated speed will only be correct after the first minute has passed.
|
||
|
|
When estimation is enabled, the final speed will be estimated during the startup interval (in this example during the first minute).
|
||
|
|
This setting is useless when frequency is 'second' (which has no startup period) or when the 'ignore speed' checkbox is selected.</p>
|
||
|
|
<p><strong>Ignore speed</strong></p>
|
||
|
|
<p>When speed is ignored during the startup period, no messages will be send to the output port during the startup period.
|
||
|
|
Moreover, the node status (in the flow editor) will not display the calculated speed.</p>
