Hi List,<br />
As I suspect my issue is something to do with mrtg I am posting it <br />
here, I have upgraded the squid box to 3.1.8 and everything is working <br />
fine except the graph part with mrtg.<br />
<br />
Details of system as follows<br />
OS FreeBSD : 8.1 <br />
Squid : 3.1.8<br />
MRTG : mrtg-2.16.4<br />
<br />
My mrtg.cfg is as below<br />
<br />
LoadMIBs: /usr/local/etc/mrtg/squid.mib<br />
EnableIPv6: no<br />
WorkDir: /usr/local/www/apache22/data<br />

I have verified that squid snmp is working through the following <br />
command<br />
<br />
#snmpget -On -m /usr/local/etc/mrtg/squid.mib -v 2c -c public <br />
127.0.0.1:3401 cacheHttpHits cacheServerRequests cacheServerInKb <br />
cacheServerOutKb cacheUptime CacheSoftware cacheVersionId<br />
<br />
This gives me results without any errors so snmp part of squid is <br />
working fine I think<br />
Now when I run mrtg I could see the following errors in mrtg.log file<br />
<br />

<br />
All I could make out from these error was mrtg not reading squid.mib <br />
file. Am I right?<br />
Now I am stuck and I suspect a broken mrtg? or did I go wrong <br />
somewhere? Do kindly let me know what went wrong and how to proceed<br />
further.<br />
Thanx in advance<br />
