RE: [squid-users] cacheDnsSvcTime to high? value = 10142

I looked a bit further and found this in the cache.log

Any ideas?
Should I have an acl entry for localhost DNS?

Hi

Just wondering what cacheDnsSvcTime relates to.
I thought it meant the average time in milliseconds that squid takes to
get a DNS request. But the values that I'm getting indicate around 10
seconds.

Strange because if I do a nslookup on the squid box it resolves
instantly

Why?
What values are you getting?

[root@taz xinetd.d]# snmpwalk -m /home/mrtg/scripts/mib.txt
XXX.XXX.XXX.XXX -p 3401 public cacheDnsSvcTime
enterprises.nlanr.squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.ca
cheMedianSvcEntry.cacheDnsSvcTime.1 = 10142
enterprises.nlanr.squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.ca
cheMedianSvcEntry.cacheDnsSvcTime.5 = 10142
enterprises.nlanr.squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.ca
cheMedianSvcEntry.cacheDnsSvcTime.60 = 10142
