host, and an additional five metrics per managed interface. The host used in this example has two
interfaces, so the results reflect metrics for a second interface as well as the de facto first interface.
The traffic generated by the data collection process, in this case:
SNMPv2c
GETBULK 748 bytes (5984 bits)
Requests:
SNMPv2c
Responses: 869 bytes (6952 bits)
Total Traffic: 1617 bytes (12936 bits)
Transaction time: .0536 seconds
Average bandwidth: 43.12 bps
% of 10Mbps Ethernet: .00000431%
% of 100Mbps Ethernet: .000000431%
This data is extremely system, time, and network specific--your results WILL undoubtedly vary.
However, for the sake of our argument, let's proceed to look at the overall network impact.
The running total of traffic generated on the network:
ICMP
Ping: 180 bytes
TCP Synthetic Transaction: 180 bytes
HTTP Synthetic 1860 bytes
Transaction:
SNMP Data Collection: 1617 bytes
Aggregate Total: 4181 bytes
Aggregate Total Bits: 33,448 bits
Aggregate Network
