Greg,
Thanks for your response. I suspected as much, but wanted to be sure.
I am creating a separate instance I guess. I have a separate .rrd file for each blade. I have a separate config file with high (>=5000) reference numbers that are aggregates. For example:
Target[switch_5000]: 40:community at switch + \
41:community at switch + \
.
.
.
64:community at switch
for a 24 port blade. Is this the 'proper' way to accomplish the task? Is there a better/faster way? I am always interested in creating less load - I am monitoring several thousand ports.
