PostRemoteLog is a tool that allows you to send information across the network to a centralized location. Three methods are currently supported: XMLRPC, Email, and Growl. It is generally aimed at system administrators who want to keep track of information such as backup post-run scripts, network monitoring scripts, UPS information, service outages, power on/off, unexpected restarts, etc. PostRemoteLog is designed to be used in other scripts. Captured data can be analyzed and aggregated as needed.
FreeBST ports monitoring is a simple solution for monitoring what has changed in installed ports on a given FreeBSD machine, i.e. what ports were upgraded, installed, or removed. No fancy dependencies: just plain Ruby and shell commands. Results in plain English text are emailed to a given address.
