SpurTracer is a push-notification based monitoring solution for heterogenous loosely coupled IT infrastructures. It complements a service-endpoint monitoring solution like Nagios with a component-level interface auto-discovery. It automatically provides a certain level of functional tracing along with many non-functional measurements (e.g. call, error and timeout rates, interface latency, component execution, etc.). While being zero config itself, SpurTracer relies on you adding push notification support to the components you want to monitor. The best way to use SpurTracer is by adding punctual tracing to components in your infrastructure on-demand.
Arandomd is a network daemon that provides statistically tested output from a single ARC4 stream cipher generator to anyone able to connect to its listening TCP port. As multiple consumers cause it to reseed itself from a separate, strong random source, it is expected to produce consistently unpredictable results for cryptographic purposes. A configurable number of tests from the Statistical Test Suite for Random and Pseudorandom Number Generators must be passed before output data is sent to the client. It may be be useful in low-entropy environments, such as compute clouds, for generating high quality key material for strong cryptography.
Monitoring::Spooler is a handy queue manager for queueing and delivery of monitoring notifications. It is able to handle several groups of on-call personnel and provides an extensible plugin mechanism to connect it to virtually any remote service which provides some kind of API. It is designed to work nicely with App::Standby.
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.
