Observed that the Cache hit rate graph can become severely out of sync with the rate that is published when observing the system using varnishstat. It turns out that using client_reqs/cache_hits is not reliable. It was observed that cache_hits + cache_misses can actually total more than client_reqs (I'm not sure how exactly). The graph should get updated to use "cache_hit/(cache_miss + cache_hit)*100" This probably requires an intermediate ungraphed point for "cache_reqs"
