6. How it works sends an SNMP query over network to router's MIB
Several SNMP queries were sent to the router to compile a list of the network interfaces present on that router, along with each interface's maximum speed and its type.
another SNMP query was sent to obtain the router's name, type, location, how long the router had been running, and the person responsible for maintaining the router.
determine how much bandwidth was consumed during the Monitoring Rate interval, and calculates the percentage of the total bandwidth available

Nagios is a popular open source monitoring tools with a reported 660,000 downloads worldwide.
Client Server News, June 2005, Issue 601
It is a host and service monitor designed to inform Network mangers of network problems before their clients, end-users or management do.
It has been designed to run under the Linux operating system, the monitoring daemon runs intermittent checks on hosts and services that network manager specify using external "plugins" which return status information to Nagios.
When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways ( , instant message, SMS, etc.).
Current status information, historical logs, and reports can all be accessed via a web browser.

23. What Nagios can monitor?
network services (SMTP, POP3, HTTP, NNTP, PING, etc.)
host resources (processor load, disk and memory usage, running processes, log files, etc.)
environmental factors such as temperature

103. Is software for monitoring the traffic load on network links
Is software for monitoring the traffic load on network links. It allows the user to see traffic load on a network over time in graphical form.
MRTG is written in perl and works on Unix/Linux as well as Windows and even Netware systems.
MRTG is free software licensed under the Gnu GPL.
It was originally developed by Tobias Oetiker and Dave Rand to monitor router traffic, but has developed into a tool that can create graphs and statistics for almost anything.

104. Prerequisites Installing In Windows
1- A current copy of Perl. For Example ActivePerl from
2- The latest version of MRTG from
Installing In Windows
Unzip MRTG to C:\mrtg
Next Install Perl. You might want to make sure that the Perl binary directory is listed in your system path.
Configure MRTG
Type: perl mrtg

105. MRTG uses the Simple Network Management Protocol (SNMP) to send requests with two object identifiers (OIDs) to a device. The device, which must be SNMP-enabled, will have a management information base (MIBs) to lookup the OID's specified. After collecting the information it will send back the raw data encapsulated in an SNMP protocol.
MRTG records this data in a log on the client along with previously recorded data for the device. The software then creates an HTML document from the logs, containing a list of graphs detailing traffic for the selected device.

106. Measures 2 values (I for Input, O for Output) per target.
Gets its data via an SNMP agent, or through the output of a command line.
Typically collects data every five minutes (it can be configured to collect data less frequently).
Creates an HTML page per target that features 4 graphs (GIF or PNG images).
Results are plotted vs time into day, week, month and year graphs, with the I plotted as a full green area, and the O as a blue line.
Automatically scales the Y axis of the graphs to show the most detail.
Adds calculated Max, Average and Current values for both I and O to the target's HTML page.
Can also send warning s if targets have values above a certain threshold.
MRTG is not limited to monitoring traffic, though. It is possible to monitor any SNMP variable you choose. You can even use an external program to gather the data which should be monitored via MRTG. People are using MRTG, to monitor things such as System Load, Login Sessions, Modem availability and more. MRTG even allows you to accumulate two or more data sources into a single graph.

110. Simple Setup: The configuration is done
through simple ASCII text files. An additional tool helps creating an initial version of the configuration file, tailored to a certain router.
Easy Maintenance: Because the logfiles are
automatically consolidated on every run and therefore do not grow in size, the system can work unattended for months without running out of disk space.
Friendliness: The HTML pages created by MRTG are easy to understand and give a good visual representation of the network load, providing a sound basis for decisions about upgrading network links.
Integrated Solution: MRTG performs all the tasks required for traffic monitoring. No external database or SNMP packages are required to make it work.

111. Performance: MRTG-2 can not monitor more than about 600 router ports in a 5-minute interval.
Flexibility: While MRTG-2 is quite configurable in general, this seems to make the users especially aware of the areas where configurability is limited, in particular when using the program to monitor time-series data other than network traffic. about 600 router ports in a 5-minute

112. SNMP Data Gathering Graphs on Demand HTML Generation Configuration
improving SNMP data gathering performance is to issue several SNMP requests in parallel. This works around network latency as well as problems with routers that answer SNMP requests slowly.
Graphs on Demand
Because the generation of graphs is quite expensive, it is not sensible to update thousands of GIF images on a regular basis. It is more efficient to generate the graphs when a user wants to see them.
HTML Generation
In MRTG-2 the look of the generated HTML pages was tuned using a large number of configuration options. MRTG-3 will work with template files and therefore make the design of HTML pages both simpler and more flexible.
Configuration
While MRTG-2 was a monolithic program, version 3 will be a set of Perl modules which can be assembled into custom monitoring applications. The user can decide which modules to use.
