Greetings! We recently saw some strange data collection/graphing issues. Is there a limit to the number of metrics being collected (Zenoss 4.2.5)? We are trying to collect 33K+ metrics. Our Zenoss server had 64 GB RAM and 16 cores. We just increased memory to 122 GB. Only strange item was memcached jumped at the same time we added a new ZenPack (last week). I'm wondering if the additional new metrics pushed us over the limit.
For example, we're not seeing any OS metrics for a particular device. Model device doesn't show any errors, and the rrd files are being updated. But "rrdtool dump ..." doesn't show any recent data. And the graph isn't being updated.
Thanks in advance, Larry
