        At the moment that is not available with Squid 2.1.

        However you can get them in Squid 2.2 with 1/5/60 minute
intervals:

        cacheRequestHitRatio OBJECT-TYPE
                SYNTAX Integer32
                MAX-ACCESS read-only
                STATUS current
        ::= { cacheMedianSvcEntry 9 }

        cacheRequestByteRatio OBJECT-TYPE
                SYNTAX Integer32
                MAX-ACCESS read-only
                STATUS current
        ::= { cacheMedianSvcEntry 10 }
