Disini yang diperlukan hanya mengkonfigurasi squid agar mendukung SNMP. Untuk lebih jelasnya mengenai MRTG silahkan klik www.mrtg.org
Langsung saja,
squid.conf
acl snmppublic snmp_community public snmp_port 3401 snmp_access allow snmppublic all
(Here you can use any community name and any valid acl name)mrtg.cfg
- Copy the mib.txt file from Squid in the mibs directory of your MRTG installation
- Add to Global Config Options of your mrtg.conf a line like the followig:
LoadMIBS: /usr/local/mrtg-2/mibs/squid.mib
(Here I have renamed mib.txt in squid.mib)
- Add targets like the following:
Target[proxy-hit]: cacheHttpHits&cacheServerRequests:public@proxy.sg.private:3401 MaxBytes[proxy-hit]: 100000 Title[proxy-hit]: HTTP Hits PageTop[proxy-hit]: <H2>proxy Cache Statistics: HTTP Hits/Requests</H2> <TABLE> <TR><TD>System:</TD><TD>proxy.sg.private</TD></TR> <TR><TD>Maintainer:</TD><TD>Serassio Guido</TD></TR> <TR><TD>Description:</TD><TD>Squid Proxy server</TD></TR> </TABLE> Suppress[proxy-hit]: y LegendI[proxy-hit]: HTTP hits LegendO[proxy-hit]: HTTP requests Legend1[proxy-hit]: HTTP hits Legend2[proxy-hit]: HTTP requests YLegend[proxy-hit]: perminute ShortLegend[proxy-hit]: req/min Options[proxy-hit]: nopercent, perminute, dorelpercent, unknaszero Target[proxy-srvkbinout]: cacheServerInKb&cacheServerOutKb:public@proxy.sg.private:3401 MaxBytes[proxy-srvkbinout]: 76800 Title[proxy-srvkbinout]: Cache Server Traffic In/Out PageTop[proxy-srvkbinout]: <H2>Cache Statistics: Server traffic volume (In/Out)</H2> <TABLE> <TR><TD>System:</TD><TD>proxy.sg.private</TD></TR> <TR><TD>Maintainer:</TD><TD>Serassio Guido</TD></TR> <TR><TD>Description:</TD><TD>Squid Proxy server</TD></TR> </TABLE> Suppress[proxy-srvkbinout]: y LegendI[proxy-srvkbinout]: Traffic In LegendO[proxy-srvkbinout]: Traffic Out Legend1[proxy-srvkbinout]: Traffic In Legend2[proxy-srvkbinout]: Traffic Out YLegend[proxy-srvkbinout]: per minute ShortLegend[proxy-srvkbinout]: b/min kMG[proxy-srvkbinout]: k,M,G,T kilo[proxy-srvkbinout]: 1024 Options[proxy-srvkbinout]: nopercent, perminute, unknaszero
Nama hostname proxy adalah proxy.sg.private, dengan public SNMP community enabled dan SNMP listen di port 3401
Please note the MaxBytes value (76800 KB/min) for Cache Server Traffic In/Out: it depends from your Proxy network interface speed.
