Rrdpy - Python RRD Utilities
rrdpy - Python RRDTool UtilitiesPython module and scripts to simplify working with RRD'sby Corey GoldbergRRDtool is the Open Source industry standard, high performance data logging and graphing system for time series data. RRD stands for "Round Robin Database". It stores data in a very compact way that will not expand over time. RRDTool is a really good back-end for storing time-series data. If you are developing tools that need a data repository and graphing capabilities, this provides you both. You create an RRD and then you begin inserting data values at regular intervals. You then call the graphing API to have a graph displayed. The neat thing about this data storage is its ‚??round robin‚?? nature. You define various time spans, and the granularity at which you want them stored. A fixed binary file is created, which never grows in size over time. As you insert more data, it is inserted into each span. As results are collected, they are averaged and rolled into successive time spans. It makes a much more efficient system than using your own complex data structures, relational database, or file system storage.

Cacti is a web based front end tool to generate graphs for RRD files. Cacti allows a user to poll services at predetermined intervals and graph the resulting data. It is generally used to graph time-series data of metrics such as CPU load and network bandwidth utilization. It has built-in SNMP support to receive management data from various devices.
Nagiostat parses performance-data from Nagios and generates graphs of trends over time. Nagiostat makes use of RRD-tool. It then generates graphs on-the-fly through a CGI-script and HTML-templates.
Octopussy is a Log analyzer tool. It analyzes the log, generates reports and alerts the admin. It has LDAP support to maintain users list. It exports report by Email, FTP & SCP. Scheduled reports could be generated. RRD tool to generate graphs.
Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization.
LPAR2RRD makes historical, future trends and nearly quot;real-timequot; CPU utilization graphs of LPAR's and shared CPU usage of IBM Power servers. It supports all kinds of logical partitions (AIX / AS400 / Linux / VIOS). It is agent less (It gets everything from the HMC / SDMC or IVM). It collects complete physical and logical configuration of all servers/LPAR's. Try live demo at http://www.lpar2rrd.com/live_demo.html
LiveGraph is a framework for real-time data visualisation, analysis and logging. It has a real time plotter that can automatically update graphs of your data while it is still being computed by your application. LiveGraph reads files in a simple CSV-style format. For applications developed in Java, LiveGraph additionally provides an API that handles all data logging and persistency issues.
A complete OpenSource Network Management System Is SNMP-Standard Oriented (tested on Cisco and Linux). It Integrates Syslog, Tacacs, RRDtool (Performance Graphs), Maps, Traps, TFTP, Autodiscovery, Sound Alerts, AAA, Modular and Extensible.
HyperGraphDB is a general purpose, open-source data storage mechanism based on a powerful knowledge management formalism known as directed hypergraphs. While a persistent memory model designed mostly for Knowledge management, Artificial Intelligence and Semantic web projects, it can also be used as an embedded object-oriented database for Java projects of all sizes. It could also be used as graph database or as (non-SQL) relational database.
Rickshaw provides the elements you need to create interactive graphs: renderers, legends, hovers, range selectors etc. It's all based on d3 underneath, so graphs are drawn with standard SVG and styled with CSS.
