snmp2xml is a program to convert snmpget output to XML. The output from snmpget, snmpwalk, or snmpbulkwalk is first filtered to correct for SNMP agent flaws and then processed into XML. This XML can be passed through xmllint to tidy it up or it can be processed by an XQuery or XSLT processor. The XML output represents all the SNMP data such that the original SNMP output can be reproduced if desired with an XSLT stylesheet (which is included). The snmp2xml converter has been tested on 7 SNMP agents: Mac OS X, Apple Time Capsule, the Billion ADSL router, the Huawei S9306 switch, the Foundry/Brocade CES and MLX-4 switches, and the Nortel 425 switch.
snmp4zabbix provides a simple SNMP interface to the Zabbix monitoring solution. This lets Zabbix monitor itself using the Simple Network Management Protocol. This is an alternate solution to the Zabbix API for integration, to some extent, with any third party software capable of understanding SNMP.
snmpd-pyagentx provides Python3 bindings for AgentX extension of the snmpd part of the Net-SNMP project. It allows you to tie into snmpd, returning your own values for OIDs or whole OID trees right from the Python code. It consists of a thin C interface for snmp_agent_api(3), provided by net-snmp project libraries, and pure Python logic for handling forwarded requests. The C code is loosely based on the python-agentx project codebase by Bozhin Zafirov.
spuug is a little tool that generates the boilerplate code for GObjects. spuug can be used for "plain" GObjects, but also for more sophisticated objects such as GTK+ widgets. It tries to be a bit smart with the code in spits out. However, understanding of GObjects/GtkWidgets is recommended.
