1. | Verify the IP address and community string of the target device you intend to poll.
|
2. | Make sure you can do an SNMP walk of the target device. If not, revise your access controls on the target device and any firewall rules that may impede SNMP traffic.
|
3. | Ensure you can do an SNMP get of the specific OID value listed in your MRTG configuration file.
|
4. | Check your MRTG parameters to make sure they are correct. Gauge values defined as counter and vice versa will cause your graphs to have continuous zero values. Graph results that are eight times what you expect may have the bits parameter set.

These quick steps should be sufficient in most cases and will reward you with a more manageable network.
