The tool
NetMRG is a tool for network monitoring, reporting, and graphing. Based on
RRDTOOL, the best of open source graphing
systems, NetMRG is capable of creating graphs of any parameter of your network.
Data Input
NetMRG was built from the ISP point-of-view, with the need to graph things
both directly accessible from SNMP, as well as more challenging sources. NetMRG
polls SNMP devices, either fixed OIDs, or dynamic ones based on indices (such
as for interfaces on a router, or disks in a linux box). These dynamic indices
can handle index changes, such as with the insertion of a card in a Cisco, with
no interruption or intervention. In order to facilitate diverse data sources,
NetMRG can run custom scripts to obtain data, as well as make arbitrary queries
against your custom MySQL databases.
Speed
NetMRG is meant to handle large amounts of monitoring. Its configuration is
primarily handled via a
MySQL database,
known for its speed and flexibility. The data gathering application is a
multi-threaded (pthreads) C++ program, compliled against SNMP libraries and
efficiently communicating with RRDTOOL using pipes.
Availability
We are currently working some pre-releases, and hope to have a full release
after we get some feedback from users. You can find all current releases on
the
download page. You may
use our
subversion tree, but as with
most subversion trees, be warned that the code is not always going to work as
intended.
Developers

as a high school project.
