Resolution

Using 10,000 elements is roughly equal to 1Mbps of bandwidth usage.

Total Traffic per one NetObject (SNMP+ICMP, inbound+outbound):

Poll: 1 KB/poll Statistics Poll: 1.5 KB/poll Rediscovery: 2.7 KB/rediscovery

Using the default values for poll and rediscovery intervals:

Poll Interval: 120s Statistics Poll Interval: 650s Rediscovery Interval: 1800s

Total Orion Bandwidth Usage is:

1 NetObject: 45 KB/h 29,000 NetObjects: 1290943 KB/h 29,000 NetObjects: 2.8 Mbps

SNMP vs WMI

SolarWinds has determined that it takes roughly the same amount of resources to complete a single (1) WMI poll as it does to complete five (5) SNMP polls.
