1. NMS LAB4 WEB based SNMP monitoring with MRTG Basic SNMP config to router Allow SNMP only from server computer MRTG  Free  easy to use to monitor few router interfaces  With many routers and switches some other tool might be better (cacti etc)

2. MRTG Multi Router Traffic Grapher Easy to use www-based router interface traffic grapher (Config creator creates ready interface monitoring config)  Can be used to graph other SNMP variables as well Requirements  Server with:  WWW-server (Apache installed on server computer) Www-root c:\program files\apachec:\program  Perl (Active Perl installed on server computer)  MRTG.zip package from http://people.ee.ethz.ch/~oetiker/webtools/mrtg/pub/ (Check c:\downloads)

3. MRTG Usage Unzip mrtg to c:\temp\mrtg (If directory exist delete it) Use configmaker to create initial config from SNMP-device (perl configmaker in Windows) (Workdir to www-servers webroot/mrtg -folder (Remember to create folder) Edit config (Check workdir and options) Use MRTG to create graphs from config (perl mrtg config.conf Use indexmaker to create nice index-page (perl indexmaker) Needed options and commandline parameters are in mrtg:s documentation MRTG ALLWAYS MONITORS TWO VALUES  Normally traffic in / traffic out
