Multi Router Traffic Grapher 

(MRTG)

The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on

network links. MRTG generates HTML pages containing PNG images which provide

a LIVE visual representation of this traffic.

MRTG consists of a Perl script which uses SNMP to read the traffic counters of your 

routers and a fast C program which logs the traffic data and creates beautiful graphsrepresenting the traffic on the monitored network connection. These graphs are

embedded into webpages which can be viewed from any modern Web-browser.

In addition to a detailed daily view, MRTG also creates visual representations of the

traffic seen during the last seven days, the last five weeks and the last twelve

months. This is possible because MRTG keeps a log of all the data it has pulled

from the router. This log is automatically consolidated so that it does not grow over 

time, but still contains all the relevant data for all the traffic seen over the last two

years. This is all performed in an efficient manner. Therefore you can monitor 200 or 

more network links from any halfway decent UNIX box.

Multi Router Traffic Grapher 

(MRTG)

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 (MIB) to look up the OIDs

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 anHTML document from the logs, containing a list of graphs detailing traffic for the

selected device.

CiscoWorks LAN Management Solution (LMS) is an integrated suite of 

management tools that simplify the configuration, administration, monitoring,

and troubleshooting of Cisco networks. Built upon popular Internet-based

standards, CiscoWorks LMS applications help enable network operators tomanage the network through a browser-based interface that can be

accessed anytime from anywhere within the network. CiscoWorks LMS

maintains a centralized list of all Cisco network devices and their credentials

that serves as a single repository for all CiscoWorks applications whether 

they are installed locally or distributed in a multiserver deployment.

This design describes the architecture, general configurations and guidelines

for the implementation of following solutions:

• Tivoli Infrastructure, Base Monitoring and Event Management

It ensures that Tivoli can communicate with the managed resources; hardware

and operating system components are monitored and a central server isdefined for event management. The Tivoli infrastructure, the measurement

data and event information produced by this first step is the basis for all further 

steps of the solution

•Database and Web Application Monitoring

Databases (Oracle, MS-SQL and DB2) will be managed with pre-configured,best-practice monitoring solutions. IBM Tivoli Monitoring for Databases and

Web Applications are installed on top of the infrastructure provided in step 1.

• Business Impact Management

The business impact management is realized using the IBM Tivoli Business

Systems Manager. Once the product is configured it will provide a map of 

business systems required for business processes.

• Helpdesk management

Helpdesk functions will be enabled to identify a business impact in case an IT-

component is not working or exceeds defined thresholds.

• Network Management

IBM Tivoli NetView will be responsible for managing all of the componentsdistributed Network. The network admin will be able to monitor their 

networking devices, define network monitors and thresholds with the solution

and receives reports and alerts on the status of the defined monitored

devices.
