I think what the question was really about was monitoring. not just metrics<br>
<br>
the use if metrics in an overall monitoring solution is important. collectd itself I view more as a metrics collection framework<br>
<br>
what is really needed as part of the answer is that collectd itself is not an alerting framework. eg they need I look at something like nagios. getting nagios checks to do threshold checks against historical metrics ( say link errors in the last 30 seconds ) is very helpful<br>
<br>
collectd itself does not necessarily know not care about individual link state<br>
<br>
original requester - hope that helps. was that really more your question/direction?<br>
