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.
Counters.pl collects the CLI counters from network devices and produces custom reports. These counters can be reset independently of the SNMP counters, and when collected weekly, can highlight issues such as connection errors that you will not see looking at graphs produced from SNMP counters. They also contain information that is not available via SNMP. The reports can be viewed on a Web site and/or sent via email. There is a flexible configuration language in which reports can be specified. The format and style of the HTML reports are controlled by Template Toolkit templates and CSS. Currently only Cisco network equipment is supported.
jmxtrans is effectively the missing connector between JMX and whatever logging or graphing package that you can dream up. jmxtrans is very powerful tool that reads JSON configuration files specifying servers/ports and JMX domains/attributes and then outputs the data in whatever format you want via special "Writer" objects that you can code up yourself. It does this with a very efficient engine design that will scale to querying literally thousands of machines. The core engine is pretty solid and writers are included for cacti/rrdtool, graphite, and stdout.
