Not all client data should be send, we would like to be able (if<br>

<p class="MsoNormal">This is the difficulty - being selective. Perhaps you could send all client data but then just ignore the hosts you don't care about, or put them on a page that nobody looks at.<o:p></o:p></p>

<div>
<p class="MsoNormal">I wonder of it's practical to script up a kind of proxy. You could use the output of "$XYMON $XYMSRV xymondboard" to list all hosts that are tagged the way you want to select then (eg tag them with a NET parameter) and also list only those
with client data.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Then with that list of hosts (or simply manage your own list in a text file), you grab the current client data with "$XYMON $XYMSRV clientlog" and send the output to "$XYMON $XYMSRV client" (with appropriate header).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Then sleep for 5 minutes and repeat.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Consideration should be given to detecting and suppressing stale client messages. Also, this technique may not be particularly efficient, so care should be taken if you have a lot of hosts to forward, and you may get bursts of high load
on your intermediate xymon server. And there could be up to 5 minutes delay, unless you poll more often and limit the client data accordingly.<o:p></o:p></p>
