NISCA (Network Interface Statistics Collection Agent) is a more flexible PHP4-based MRTG replacement. It supports both SNMP and reading localhost's /proc/net/dev device file directly for statistics gathering. It uses MySQL to store collected data in, and stores statistics for bytes transferred, packets transferred, transfer errors, and dropped packets separated into a per interface incoming and outgoing set. It generates both graphs and a textual report table using the data from any timeframe contained in the database. The entire package runs using PHP4; it uses the CGI binary version of PHP for stats collection (running in the background as a "daemon") and either the CGI or Apache module versions to generate the GUI form and reports. It can also import existing MRTG logfiles.

Release Notes: "95th-percentile" data massaging and the ability to make the text-only reports "time-zoomable" (the same way the graphs are) were added. A few minor bugfixes were also made.
Release Notes: Everything wrong with versions 2.3 and 2.3.1 was fixed. The look and feel was made more attractive and easier to customize.
Release Notes: The PHP SNMP functions were replaced with calls to the snmpwalk and snmpget binaries from the ucd-snmp package. Graphs are now image maps that allow zooming into a time range with one click. The SNMP collector completely rewritten and can now cache collected stats if the database connection is lost. Watermarks of any kind can be added to graph images, and a few bugfixes were made.
Release Notes: This release includes support for multiple-interface total bytes transferred graphing, a data re-averaging utility, multiple interface naming methods ("ifIndex", "ifPhysAddress", etc), a Committed Information Rate line to graphs, aliases for hosts, and one or two bugfixes.
Release Notes: Minor bug fixes were made. Context-sensitive help is now available on all pages that need it. The database was restructured, resulting in a 44% smaller database and much faster report generation. New features include the ability to generate graphs as PNG or JPEG, and the ability to use 64-bit counters on some interfaces but not others on the same host.
