TrackNode: SNMP-Based Network Node Polling Suite Copyright (C) 2013, Jason Stultz This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. DESCRIPTION: TrackNode is designed to become a robust, extensible architecture for polling arbitrary system metrics over SNMP. This project is still in early experimental phases, so functionality is limited (the current code is more of a PoC than anything else). No warranties are provided for the functionality of this code. GPLv3 currently applies to all source provided with TrackNode; the license can be found at All rights not expressly conveyed within the license agreement are reserved by the primary developer (excelsiorjss). Note: This project is not yet deployment-worthy. Download and install at your own risk. NOTES: As TrackNode is currently a very young project, all of the code currently available through SourceForge is "concept code," meaning that it is code with a very loosely defined organizational architecture. Plans are to further organize, optimize, and render both scalable and modular, the code. INSTALLATION: TrackNode currently consists of two installable components: SENSOR: This component is to be installed on the system to be monitored; it is to include SNMP configuration tweaks, polling scripts, and local administrative scripts. As of now, I have only posted the polling scripts; however, the configuration can be replicated by configuring snmpd to extend services to the scripts using the "extend" configuration item in snmpd.conf. Note that, in order for the web console to function as it stands, the "." OID subtree must be available via the community string "public". This is subject to change as the project evolves further. This component requires Apache and Perl::CGI to be installed on the system, as well as snmpd package. This component also requires ladyada's DHT interface, available at Finally, while it is not necessary to have for functionality, this component is meant to work alongside a DHT22 sensor installed via the #4 pin of a Raspberry Pi. CONSOLE: This component is meant to be installed on a system being used to monitor an array of sensor nodes. It consists of a network monitoring component (via SNMP and ICMP), a parsing component, and the presentation web console. httpd, perl, Perl::CGI, Net::SNMP, and 'snmptraverse()' must be made available on the console system. The "Select Multiple Sensors" and "Select All Sensors" options are currently designed to look within the network; however, changing this is as simple as updating index.cgi. FEEDBACK All feedback should be directed to the SourceForge message boards at LICENSE Unless stated otherwise, the entire TrackNode project, and all components (scripts, files, binaries) therein, are licensed under GPLv3, All rights not granted expressly within the above licensing agreement or below are reserved to the primary developer, excelsiorjss (Jason Stultz).
