<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been trying to make use of the “match_regex” to filter out the individual CPU metrics. I am looking to use the Aggregated CPU metrics instead. The metrics then are to be written to a RabbitMQ queue. The filtering out of individual
CPU and the Aggregation of CPU metrics work fine. But, the “match_regex”seems to be unable to dispatch values to the RabbitMQ queue.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is how my “match_regex”plugin looks like :-<o:p></o:p></p>

<p class="MsoNormal">The corresponding “aggregation.conf” and “amqp.conf” lie in “/opt/collectd/etc/collectd.d/”. The “Include” directive in “/opt/collectd/etc/collectd.conf” includes all the *.conf files in “/opt/collectd/etc/collectd.d/”. I switched on debug
logs and this is all that I see :-<o:p></o:p></p>
