Hi All,
Our NOC have two kinds of monitoring tool, one is Cacti -SNMP-based, other ones are netflow tools for neflow V9. We compared the data statistic status and showing up time in both kinds of tools, and we observed the netflow ( more than one tool) data showing up/collecting time are always around 30 minutes behind than Cacti link diagram. So I am wondering if our netflow setting have a problem on ASR9000 device.
I attached the netflow setting example here, please take a look and let me know which option would be a root cause for this issue.
many thanks
Eric
