In short, Torrus is an alternative software platform to
Cacti. In most cases it brings more
flexibility and performance. We are able to poll
1 million SNMP OIDs every 5 minutes from a modern server.
Torrus is designed to be the universal data series processing
framework. Its scalable hierarchical design, application-independent
core, inremental configuration processing, and highly customizable
architecture make Torrus an attractive choice both for small
installations and for big enterprise or carrier networks. Although most
of our users deploy Torrus for SNMP monitoring, it might be useful for
data series of any nature. Tobi Oetiker's RRDtool is used for data

Currently Torrus consists of the following parts:
Configuration compiler and validator. It processes the
XML configuration files and saves the configuration into internal
database. The compiler is incremental, and it only processes the XML
files that have changed since last run.
User web interface. The web interface provides
authentication and authorization, and it allows the user to navigate
through the datasource tree, and see the grahs. All generated output is
controlled by configuration parameters and templates. Each graph image
or HTML page has a persistent URL, so the output can easily be
intergated into other interfaces.
Thanks to David M. Town's
Net::SNMP Perl module, Torrus has got an extremely efficient SNMP
data poller, with ability to poll hundreds of thousands of SNMP objects
from a single server. Modular collector core architecture allows further
extension with new collector and storage types. Any datasource can have
its own polling schedule.
SNMP Device Discovery Tool.
Devdiscover is a modular, flexible, and expandable tool for
automatic generation of Torrus configuration files. New device types and
MIBs are easily added as independent Perl modules. Thanks to our
contributors, the number of supported devices and vendors is constantly
Billing reports generator.
Torrus can be configured to store the network traffic usage in an SQL
database (without RRDTools' aggregation and interpolation), and produce
monthly reports on traffic volume and 95th Percentile bandwidth usage.
All data, regardless of their type and nature,
can be monitored according to the user-defined rules. The rules can also
include the datasource-specific parameters, e.g. boundary values etc.
The following types of action may be combined for event reporting:
1) Displaying the list of alarmed datasources; 2) E-mail notification;
3) SNMP trap; 4) Any custom executable. Thresholds are specified by RPN

Features of Torrus
Data-oriented design. Most of the existing frontends are SNMP-centric.
In Torrus, the SNMP collector is not the central part,
but rather one of possible data sources. It is easy to integrate
some existing RRD files that are updated by some external agents.
Multiple independent datasource trees in one instance
User authentication and authorization. Users belong to groups,
and each group has privileges to browse a certain subset of trees.
Flexible hierarchical configuration in XML format. Multuiple XML
files are processed additively.
Git repository as configuration back-end. All configuration is
stored in a Git repository, and this allows incremental processing of

Torrus is now capable of sending the SNMPv2c traps, with the variables
described in the corresponding MIB file.
