Why ?

A picture is worth a thousand words ! – Frederick R. Barnard, 20th century

What to monitor ?

 Backbone and critical equipment – routers,

switches, firewalls, load-balancers, etc

 Servers and services  Values of traffic  Error rates  Transport network equipment, if available

How

Always use Industry standards for collecting data like:

 SNMP  NetFlow v5/v9 and IPFIX

E-infrastructure Autumn Workshop, Chisinau, September 8-11, 2014

slide-6
SLIDE 6

Tools

 OSS Software largely available  SNMP based:

 NMIS  Cacti  Weathermap

 NetFlow based:

 NFSEN/NFDUMP

 Custom software  Maps using free API from Google Maps (CEENGINE

VTR)

 Maps using different technologies: JS,

ActionScript, PHP, SVG, etc (RoEduNet WeatherMap)

 Proprietary software  For optical network

Facts for Romanian Education Network !

 NMIS:  home: https://opmantek.com/network-

management-system-nmis/

 90 routers and 20 switches monitored  Uses SNMP for collection of data  Xen based VPS - 1 x Xeon 2.4Ghz, 1G of

memory, 64G of disk

 OpenSuSE (64 bits)  Average load of the server – 2-3  3G of disk space for data since 2009 (5 years)  Requires some knowledge of Linux system

and services for setup

Facts for Romanian Education Network !

 Cacti  home: http://www.cacti.net/  Uses SNMP for collecting data  Can easily monitor any OID that returns an

integer (think about temperature, number of routes, etc)

 Easy deployment and small requirements

(web server with PHP)

 Easy administration using a web interface  Authenticated access, configurable per user

views

Facts for Romanian Education Network !

 Weathermap  home: http://www.network-

weathermap.com/

 Uses RRDs from NMIS  Can be build using only OSS technologies like

SVG and JavaScript

 Is very flexible and can accommodate all kind

  • f data visualisation

 Major downside – requires some

programming skills

Facts for Romanian Education Network !

 Nfsen/nfdump  home: http://nfsen.sourceforge.net/  Uses NetFlow (v5 or v9)  Can have profiles of subset of data (think

about graphs by service type or by IP addresses)

 Supports plugins (Perl knowledge is required)  Supports alerts based on threshold or

deviation from the mean

 Major downside – lots of hardware needed on

big networks: 1 server for data processing (8 x Xeon E7000 2.8Ghz with 64G of memory) and 22T of storage for 6 month of NetFlow’s exported by 13 core routers (8-12Gbps average traffic).

Facts for Romanian Education Network !

 CEENGINE Visual Traceroute  home: https://noc.ceengine.eu/vtr/  Based on Google Maps  Heavy use of JS and custom web services  Backend and data collector written in Perl

slide-17
SLIDE 17

Facts for Romanian Education Network !

 Custom maps  home: N.A.  Frontend based on JS and HTML5  Backend uses multiple OSS services and

technologies:

 Lots of data input points: email, http, logs,

  • ther databases.

 PostgreSQL as database server  Perl for data processing  REST API

 Low hardware requirements: 1 Xen based VPS

with 1 Processor and 4G or memory.
