screen-scraper is a tool for extracting data from Web sites. It works much like a database that provides access to the information of the Web. It provides a graphical interface allowing you to designate URLs, data elements to be extracted, and scripting logic to traverse pages and work with scraped data. Once these items have been created, screen-scraper can be invoked from external languages such as .NET, Java, PHP, and Active Server Pages. It can be scheduled to scrape information at periodic intervals, and can automatically write extracted data to CSV files.
trend is a general-purpose, efficient trend graph for "live" data. Data is read in ASCII format from a file or continuously from a FIFO, and is played in real-time into a multi-pass trend (much like a CRT oscilloscope or a strip chart). trend can be used as a rapid analysis tool for progressive or time-based data series together with trivial scripting.
nexB OpenAssets is a tool for inventorying, managing, and monitoring applications, software, hardware, networks, and generally any IT asset. It is designed so that system administrators, IT, and finance can determine what they have, how it is configured, what it is used for, and how much it is being used, so that informed decisions can be made. It complements existing network management software, integrates with a growing number of protocols and tools, and features no-agent discovery and inventory, configuration management including dependencies and correlation, monitoring, and reporting. It makes extensive and innovative use of XML, Xpath, and Xquery.
Bandwidth Monitor NG is a small console-based live network and disk I/O bandwidth monitor for Linux, BSD, Solaris, Mac OS X, and others. It supports /proc/net/dev, netstat, getifaddr, sysctl, kstat, /proc/diskstats, /proc/partitions, IOKit, devstat, and libstatgrab. An unlimited number of interfaces and disks are supported. Interfaces and disks are added or removed dynamically from the list. You can white or blacklist interfaces and disks. The output includes KB/s, Kb/s, packets, errors, average, max, and total sum, and can be viewed via curses, a plain console, CSV, or HTML. Configuration can be done through a config file or the command line.
BixData is a cluster management tool that includes monitoring and system administration features. It monitors services (HTTP, ping, POP3, SMTP), performance, and processes. It has a management console for VMWare and Xen that supports multiple virtual machine hosts and guests. It can create critical notifications and send email alerts for any system event (HTTP, ping, CPU, memory, SMART diagnostics, VM stats). A graphical desktop supports real-time dynamic graphs. The runtime agents and server components are lightweight and easy to set up and run.
Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
Netdisco is a Web-based network management tool. Users can locate the switch port of an end-user system by IP or MAC address. Data is stored using a SQL database. Cisco Discovery Protocol (CDP) optionally provides automatic discovery of the network topology. The network is inventoried by both device model and operating system (like IOS). It uses router ARP tables and L2 switch MAC forwarding tables to locate nodes on physical ports and track them by their IP addresses. For each node, a time stamped history of the ports it has visited and the IP addresses it has used is maintained. It gets all its data, including CDP topology information, with SNMP polls and DNS queries. Security features include a wire-side Wireless Access Point (AP) locator.
