Munin

Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort.

Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine “what’s different today” when a performance problem crops up. It makes it easy to see how you’re doing capacity-wise on any resources.

Munin uses the excellent  “‹RRDTool  (written by Tobi Oetiker) and the framework is written in Perl, while plugins may be written in any language. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for data. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).

This site is a wiki as well as a project management tool. We appreciate any contributions to the documentation. While this is the homepage of the Munin project, we will still make all releases through Sourceforge.

Download

All versions are available from  “‹  “‹Sourceforge.

The stable branch is the 2.0.x line, development is happening in 2.1.x.

Munin 2.0 is available in repositories for (at least) the following Linux distributions:  “‹Debian, Ubuntu, Fedora, Red Hat, Red Hat Enterprise Linux, Mandriva, Gentoo and is also available in FreeBSD ports.

SIP Router Project

The SIP Router Project  is the common development framework for projects related to  SIP Express Router (aka SER), referred further as x-SER projects. The projects that joined the initiative so far are:  SIP Express Router (SER)  ““ the initial project started in 2001 (released under GPLv2 in 2002),  Kamailio (OpenSER)  ““ the project started as fork of SER in 2005 and  OpenIMSCore  ““ the IMS prototyping project branched from SER.

The latest stable branch of the project is 4.1 ““ created in December 2013. This code base is used to release  Kamailio 4.1.x  versions.

SER LogoOpenSER Logo

Since January 2010, by release of v3.0.0, SIP Express Router (SER) and Kamailio (OpenSER) are the same application, built from same source code. The differences are in database structure used to store subscriber profiles and routing information, which is a matter of what modules are used (e.g., for authentication, user location, a.s.o.). SER refers now to this application used with modules_s/auth_db module while Kamailio is same application but with modules_k/auth_db module.

The main goals for the project are:

  • bring together the developers and user communities of these projects
  • reduce maintenance overhead
  • avoid duplicated efforts in development
  • develop a core framework that is flexible, extensible and scalable
  • promote and build a solid open source SIP server project
  • ensure business credibility
  • make future forking undesirable, this harms everybody, affects credibility and business

On  October 10, 2009, source code of SER and Kamailio was completely integrated in SIP Router GIT repository and branches were created to prepare 3.0.0 releases. On  January 11, 2010, Kamailio 3.0.0 was released.

SIP Router Project Facts:

  • integration has finished ““ one source code tree for Kamailio and SER
  • single development environment for Kamailio and SER SIP servers ““ new features are available in both at once
  • releases to easy migration and maintenance depending on which project you are more familiar ““ see  releases page for more details
  • you can run mixed Kamailio and SER modules in the same SIP server instance
  • provides all features of Kamailio and SER in one SIP server
  • over 50 developers, more than 20 very active
  • over 160 extensions (modules) all together
  • command line tools (sercmd, kamctl, “¦) and web management interfaces (siremis, serweb)
  • dozens of  new features in 3.0.0 releases.
  • more feature to come in  future releases.

NfSen – Netflow Sensor

NfSen is a graphical web based front end for the  nfdump  netflow tools.

NfSen allows you to:

  • Display your netflow data: Flows, Packets and Bytes using RRD (Round Robin Database).
  • Easily navigate through the netflow data.
  • Process the netflow data within the specified time span.
  • Create history as well as continuous profiles.
  • Set alerts, based on various conditions.
  • Write your own plugins to process netflow data on a regular interval.

Different tasks need different interfaces to your netflow data. NfSen allows you to keep all the convenient advantages of the command line using nfdump directly and gives you also a graphical overview over your netflow data.
NfSen is available at  sourceforge  and distributed under the  BSD license.
