Hi All Squiders! I have run many squid boxes over the years but never really worried about any stats out of them other than cache manager and sarg. We have just put a new box in to frontend an F5 Link controller which frontends a few dsl lines. I now really need to tweak this box for really good performance so have tried mrtg to do this. Here is the problem! I have had to change all the nice MIB names to dreadful oid numbers to make it work. Here is the config. Gentoo linux with squid 2.6.STABLE12 and mrtg 2.15.1 The relevant lines from squid.conf are acl snmppublic snmp_community public snmp_port 3401 # Gentoo must specify this snmp_access allow snmppublic all The rest are all commented out to use defaults My mrtg config file looks like this # #################### # Global Configuration # #################### RunAsDaemon: yes EnableIPv6: no Options[_]: bits,growright WorkDir: /var/www/squid IconDir: /images/ LoadMIBs: /opt/mrtg/squid/squid.mib # ################################################# # Common stuff # ################################################# PageTop[^]: <H1>Squid3 Squid Traffic Stats</H1><HR> PageTop[$]: Contact Angela Williams if you have any questions<HR> PageFoot[^]: <i>Page managed by <a href="mailto:angie@xxxxxxxxx";>Angela Williams </a></i> # ################################################# # Configuration for each Target you want to monitor # ################################################# Target[cacheServerRequests]: 1.3.6.1.4.1.3495.1.3.2.1.10.0&1.3.6.1.4.1.3495.1.3. 2.1.10.0:public@squid3:3401 MaxBytes[cacheServerRequests]: 10000000 Title[cacheServerRequests]: Server Requests @ squid3 Options[cacheServerRequests]: growright, nopercent PageTop[cacheServerRequests]: <h2>Server Requests @ squid3</h2> YLegend[cacheServerRequests]: requests/sec ShortLegend[cacheServerRequests]: req/s LegendI[cacheServerRequests]: Requests LegendO[cacheServerRequests]: Legend1[cacheServerRequests]: Requests Legend2[cacheServerRequests]: These are the errors I see in my /var/log/mrtg.log file 2007-07-06 13:58:19 -- Started mrtg with config '/etc/squid-mrtg.conf' 2007-07-06 13:58:19 -- Unknown SNMP var cacheUptime at /usr/bin/mrtg line 2149 2007-07-06 13:58:19 -- Unknown SNMP var cacheSoftware at /usr/bin/mrtg line 2149 2007-07-06 13:58:19 -- Unknown SNMP var cacheVersionId at /usr/bin/mrtg line 2149 2007-07-06 13:58:19 -- Use of uninitialized value in concatenation (.) or string at /usr/bin/mrtg line 2165. 2007-07-06 13:58:19 -- Use of uninitialized value in concatenation (.) or string at /usr/bin/mrtg line 2165. Repeated every 5 mins! Using snmpget with a -m and the mib file gets me the correct results but it seems to me that mrtg is not using the squid mibs. I have always tried to avoid snmp until now! New learning curve again! I could have a go at Henrik Nordstrom's rrdtool stuff but that is another learning curve! I will post this to the mrtg list once I get subscribed!
