Hi all,

I have a website that’s heavily cached – or intended to be heavily cached
via Nginx .

But somehow looking at the page response time I feeling there is a very
high eviction/invalidation rate.

Now is there way I can look at the cache status in Nginx for different. I
don’t use the purge module.

The only way I check cache status is through

add_header X-Cache-Status $upstream_cache_status;

I want to o/p the cache status to a RRD tool and look at the metrics.

Is this possible?
