Check the view.json file for number of interfaces and interface type. Look for common things such as interface type and description. Use models or Config.nmis to disable collection.
Models
When troubleshooting models it's important to know if all the OID's that have a 'friendly name' are referenced within Model files have been defined in /usr/local/nmis8/mibs/nmis_mibs.oid. Some Model files import or call other Model, Graph or Common files. If an OID 'friendly name' has not been defined in nmis_mibs.oid it may not be obvious which model file is causing the problem. In order to validate friendly names more easily the script below has been provided. It will parse all the OID friendly names out of the model files and look for them in nmis_mibs.oid. If they are not found the operator will be notified. At some point this script should be converted to perl; this would make it much faster.
