Cacti is a complete frontend to RRDTool. It stores all of the necessary information to create graphs and populate them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain graphs, data sources, and round robin archives in a database, Cacti also handles the data gathering. There is SNMP support for those used to creating traffic graphs with MRTG.
Xplico is an IP traffic decoder that extracts data from an Internet traffic capture. From a pcap file, it can extracts each email (POP, IMAP, and SMTP protocols), all HTTP content, VoIP calls (SIP, RTP, H323, MEGACO, MGCP), IRC, MSN, and so on. It isn't a packet sniffer or a network protocol analyzer, but rather an IP/Internet traffic decoder or network forensic analysis tool (NFAT).
Andrisoft WANGUARD is an enterprise-grade traffic monitoring and DDoS detection and protection solution that delivers the functionality NOC, IT, and security teams need to effectively monitor and protect their network through a single, integrated package. WANGUARD Sensor relies on sFlow, NetFlow, IPFIX, or Port Mirroring / SPAN.
NetMRG is a network monitoring, reporting, and graphing system. Using MySQL, PHP, C++, pthreads, and RRDTOOL, it is capable of monitoring thousands of arbitrary values at user-configured intervals (typically 5 minutes). Graph templating allows network and system admins to begin monitoring routers, switches, servers and other devices with minimal setup overhead. NetMRG is also capable of responding to programmable events, such as variables exceeding accepted tolerances. NetMRG can be deployed in server hosting and ISP environments, allowing users to view only their own equipment's bandwidth or traffic graphs.
BBStatus is an IP accounting package and an SNMP and IP monitoring tool for Linux. It collects, summarizes, and displays the values from its database. It can be used for IP accounting (allows you to design various kinds of accounting filters), SNMP monitoring (collects data making SNMP requests), ICMP monitoring (stores and summarizes values like min, avg, max reply time, and packet loss), and client traffic filtering (using various types of filters). It also provides user based access so that every user can log in and visualize various data (depending on access rights). It requires PostgreSQL, Apache with mod_auth_pgsql, Perl(Net::SNMP), and RRDTool.
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.
Collax Business Server is an all-in-one Linux server for small- and medium-sized businesses. It delivers all the important network services within a heterogeneous business environment for communication, infrastructure, compliance, groupware, and storage, all in a reliable and secure way which is easy to manage. It also provides essential security functions such as firewalling and virus and spam filtering, to protect against hacker attacks, viruses, and unsolicited email messages.
BGPHist is a tool that receives MP-BGP updates, decodes them, and writes them to a database for logging and monitoring purposes. It supports not only Internet routes, but also IPv4 VPN, IPV6 VPN, and L2VPN. It sounds text output, MySQL databases, and Oracle databases. For the MySQL backend, there is also a simple PHP frontend. It could be used to monitor and log an ISP's customer activity for Internet and VPNs, as a passive BGP looking glass, or as a backend for some external monitoring and accounting system.
