Overview

• Windows-based Application Neon Software, Inc
• Monitor switches, routers, hubs, servers. Etc.
• SNMP and MIB II
• Automatically create
• utilization graphs
• daily, weekly, and monthly quality of service
  (QoS),
• Receive alerts for both non-responsive devices
  and traffic thresholds
• Monitor 5, 10, 20 or 100 devices

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

  other network parameters like memory and CPU
  utilization.
• Provides system administrators with live readings
  and periodical usage trends of leased lines,
  routers, firewalls, servers, and many other
  network devices.

How it works?

• Supports the three most common methods of data
  acquisition
• SNMP (Simple Network Management Protocol) to
  access traffic counters or other readings from
  SNMP enabled devices (most common)
• Packet Sniffing to look at incoming/outgoing
  network packets that pass through a network card
  of a compute.
• NetFlow for analyzing Cisco NetFlow packets sent
  by Cisco routers

56

  sensors
• Works with most switches, routers, firewalls, and
  other network devices from Cisco, HP, 3Com,
  Linksys, Nortel, etc., with various other
  devices (e.g. Windows PCs or network printers).

57
User Interface

• Monitoring data can be accessed via a Windows GUI
  and/or a web based front end
• Integrated web server for remote access (no
  external web server necessary)

  can be configured for
• Errors (e.g. device is not reachable)
• Reaching traffic limits (e.g. more than x MB
  transferred per day or month)
• Reaching traffic or usage thresholds (e.g. more
  than 700kbit bandwidth for more than one hour)

Using PRTG

• When we run PRTG for the first time, it does not
  have any sensor to read. We need to add sensors
  so that it can collect data accordingly
• After we have added some sensors, the main window
  looks like the window on following slide
• (Example on adding a sensor is given on some
  next slides)

68

Outline

• Setup and Installation
• How does it work?
• Features
• Examples
• key elements to the success of MRTG-2
• The main problem areas in MRTG-2

103
Definition and General Info

• 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
Setup and Installation

• Prerequisites
• 1- A current copy of Perl. For Example
  ActivePerl from http//www.activestate.com/Product
  s/Download/Download.plex?idActivePerl
• 2- The latest version of MRTG from
• http//oss.oetiker.ch/mrtg/pub
• Installing In Windows
• Unzip MRTG to C\mrtg-2.14.6
• 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
How does it work?

• 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
Features

• 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 emails 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.

key elements to the success of MRTG-2

• 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
The main problem areas in MRTG-2

• 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
Future Features MRTG-3

• SNMP Data Gathering
• 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.
