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.
Sagan can alert you when events are occurring in your syslogs that need your attention right away. It can store events into a Snort database, so your IDS/IPS data and log data are in the same place. This enables a single console, like Snorby or BASE, to view not only your IDS/IPS data but your log (syslog, SNMP, etc.) data as well. Sagan will correlate the data for you. It also uses 'Snort-like' rule sets, which means it is compatible with Snort rule set management software. It supports multiple output formats that any network administrator will find useful. Sagan can also stop threats based on log analysis via "Snortsam". This allows Sagan to communicate with various types of network devices (Cisco routers/ASA/etc., Linux iptables, etc).
aerotools-ng provides a C interface for accessing the Aquaero5 USB device by Aqua Computer. It consists of a set of functions for data access and conversion, and a commandline tool using these functions as an example implementation. It also includes utilities for exporting sensor data to SNMP to be used by NMS and other monitoring/graphing tools.
