Hi all, I am going to monitor squid proxy server. So I have added below lines squid.conf file. acl snmpmanager src 192.1.54.62 acl snmppublic snmp_community public snmp_port 3401 snmp_access allow snmppublic snmpmanager snmp_access deny all snmp_incoming_address 0.0.0.0 snmp_outgoing_address 0.0.0.0 below URL helped me http://www.squid-cache.org/mail-archive/squid-users/200010/0751.html in addition to that, below squid wiki also helped me. http://wiki.squid-cache.org/SquidFaq/SquidSnmp Any way, here are outputs of the snmpwalk commands. [root@mail ~]# snmpwalk -v2c -c public 192.1.54.62:3401 .1.3.6.1.4.1.3495.1.1 SNMPv2-SMI::enterprises.3495.1.1.1.0 = INTEGER: 232 SNMPv2-SMI::enterprises.3495.1.1.2.0 = INTEGER: 4464 SNMPv2-SMI::enterprises.3495.1.1.3.0 = Timeticks: (101615) 0:16:56.15 the below command with -m /etc/squid/mib.txt [root@mail ~]# snmpwalk -m /etc/squid/mib.txt -v2c -c public 192.1.54.62:3401 .1.3.6.1.4.1.3495.1.1 SQUID-MIB::cacheSysVMsize.0 = INTEGER: 232 SQUID-MIB::cacheSysStorage.0 = INTEGER: 4464 SQUID-MIB::cacheUptime.0 = Timeticks: (99625) 0:16:36.25 They both give outputs. I have already installed snmp and mrtg RPMs. pls see below for installed RPMs. [root@mail ~]# rpm -qa |grep snmp net-snmp-utils-5.1.2-11.EL4.11 net-snmp-5.1.2-11.EL4.10 net-snmp-libs-5.1.2-11.EL4.10 [root@mail ~]# rpm -qa |grep mrtg mrtg-2.10.15-2a Now, I need to generate mrtg.cfg file. How to do it? if I generate mrt.cfg, I will be able to issue the command env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg and indexmaker commad to generate index.html as follows. indexmaker --output=/var/www/mrtg/index.html /etc/mrtg/mrtg.cfg Any advice pls? -- Thank you Indunil Jayasooriya
