GO Netty SNMP

Network Device information Discovery via SNMP

Netty_snmp is a flexible,powerful,high performance tool for network device information collection. It will recognize network device's manufacture and platform(netmiko driver) automatically through SNMP SysObjectId and collect a lot of network basic information with friendly output format and exceptions traceback.

Inspirations of SNMP and why not command line tools(CLI):

CLI output is un-structure data, we need use regex/textfsm liked tools to extract the information from network device output. It's very painful to maintain the string-based regex code and very hard to extend. SNMP is fast, stable to get and all data is structured which is easy to handle by code, also it's much easier to maintain the codebase, some of items is generic for all network manufacturers, such as interface, hostname, lldp neighbors. One time coding and support all vendors, fancy, right? So, personally use snmp to collect basic information of network device is a better choice than CLI.
