The Management Information Base (short: MIB) describes the information over a network management protocol can be (eg SNMP) queried or modified.
...
The Simple Network Management Protocol (English for "Simple Network Management Protocol", shortly SNMP) is a network protocol that was developed by the IETF to network elements (eg routers, servers, switches, printers, computers, etc.) from a central monitor and control station, and to be able to.

To see information about a network device, you need 4 things. First, the structure of information (MIB), secondly to be able to query a protocol to this Protocol (SNMP), the third, a service of providing information (snmpd) and of course a tool to execute the queries.

On the command line there is for example snmpget and snmpwalk (to name only two times). But it needs to know the structure of the information very well. There are much simpler tools with graphical user interface, called the mibbrowser. A mibbrowser that runs on all operating systems and at least in the personal edition is free to use, comes from iReasoning .

The iReasoning mibbrowser is itself written in Java. An installed Java runtime environment is therefore a prerequisite for the installation. After starting divides the window (as pictured) in 3 areas. The MIB's links are displayed in a tree view. The Personal Edition is there a maximum of 10 MIB's are linked.
Among them there is detailed information on the MIB entry and right of the query results appear. For snmp tables (eg interfaces), there is an extra table view (Ctrl + T), otherwise all snmp commands (as in the command line tools) support. In connection settings, in addition, the snmp version and the port that should be asked about, are subject to change.

Conclusion:
Although the command line and I really like their tools, the iReasoning mibbrowser is in displaying information about snmp but much more comfortable. The free Personal Edition is for me perfectly adequate for everyday use. A comparison of the functions of the different editions (Personal, Professional, Enterprise) are here .

All major Linux Distributtionen nowadays bring packages for the Open Source monitoring tool Nagios with. However, Nagios has the merit of its expansion (and, of course, due to its low cost) has prevailed in many companies.

The integration of extensions (such as MK or nsca live status) is associated with some manual work. This is the programmers of these tools and also noticed they have simply joined together and share their knowledge and software in the Open Monitoring Distribution (OMD) together.

OMD (version 0.42) holds in its packets (for SLES 11, Debian 5.0, Ubuntu 10.04 and RedHat / CentOS 5.4 and 5.5) Nagios itself, plus these enhancements:

• nagvis
• pnp4nagios
• rrdtool / rrdcached
• nagios-plugins
• Check_mk
• MK Live Status
• MultiSite
• dokuwiki
• nsca
• check_nrpe

Another advantage of OMD is the tenancy. So you can run multiple independent environments Nagios on a server that can run on different OS users. An instance is created and starts with you:

  omd create foo
 omd start foo 

OMD is always installed below /opt/omd and is thus independent of the installation paths of different Linux distributions.
With the integration of different tools has been taken to improve the performance. It was deliberately left out the I / O-heavy NDO and instead set on MK Live Status, which directly accesses the Nagios data in main memory.

Those who prefer to be Nagios compiled by hand, yet not have to do without the other benefits of OMD. Corresponding tar balls are in addition to the packages in the download area available.

From our holiday there are a few links.

MultiSite

Multi-site is an alternative Web interface for Nagios network monitoring tool based on MK Live status.

MK Live Status

MK Livestatus accesses the main memory available information from Nagios. This kind of gathering information is compared to NDO extremely fast and very resource friendly.

Nagios - Open Source Monitoring

Nagios is a fork of Nagios and tries its history grew out of the inadequacies of current approaches to improve. The configuration files of these monitoring tools are compatible.

Easily sort of HTML Tables with jQuery

A great article on how to simplify the sorting of tables using jQuery.

Asual | Summer - The HTML5 presentation layer library for Java

Summer boasts of being the next-generation presentation layer library for Spring MVC to be. Let's see.

This year was my first time at the Open Source Monitoring Conference in Nuremberg. Focus of this conference is open source monitoring solutions for monitoring servers on network components to SERVICEN within the company. The program can be best described with the name of a lecture - "Pimp my supervision."

It was interesting to see how to use open source solutions, many companies such as Nagios and Icinga and the versatility of these tools. The higlights for me were the performances of the Nagios fork Icinga , the tool MK Live status and the fact-based multi-site .

The event was perfectly organized and I would like to thank all the organizers once again. The dates for next year related to the 09.11. / 11.10.2011 fixed already. I'm happy again.

The one with the open source Nagios monitoring well its servers and network components, is well known. The community is very large at around Nagios. But what they do is in the Japanese experiment on himself quite unique. But see for yourself:
