|

|
|
<p>A simple node to throttle down passed through message amount.</p>
|
||
|
|
<p>Just insert the throttle node in between two others, and the passed through message amount can be limited by different parameters.</p>
|
||
|
|
<p><strong>By Time:</strong><br/>
|
||
|
|
Limits the passed through messages by a given amount of time.
|
||
|
|
For example: setting the node to <code>10 seconds</code> means, that only one message in ten seconds will be forwarded.</p>
|
||
|
|
<p><strong>By Count:</strong><br/>
|
||
|
|
Limits the passed through messages by a given count.
|
||
|
|
For example: setting the node to a count of <code>5</code> means, that only every fifth message will be forwarded.</p>
|
||
|
|
<p><strong>By Block Size:</strong><br/>
|
||
|
|
Limits the passed through messages by a given block size.
|
||
|
|
The counter will be reset when a message with <code>msg.reset</code> was received.
|
||
|
|
For example: setting the node to a block size of <code>5</code> means, that only the first five messages will be forwarded.</p>
|
||
|
|
<p><strong>By Reset:</strong><br/>
|
||
|
|
Will only pass through a single message, when a message with <code>msg.reset</code> was received before.</p>
|
||
|
|
<p>Every other messages will be dropped!</p>
