Cache

proxy.node.cache.bytes_free

The difference between proxy.process.cache.bytes_total and proxy.process.cache.bytes_used.

Represents the amount of space allocated to the cache which is not currently in use by objects.

proxy.node.cache.bytes_free_mb

The value of proxy.node.cache.bytes_free expressed in megabytes.

proxy.node.cache.bytes_total

The total number of bytes allocated to the cache.

proxy.node.cache.bytes_total_mb

The value of proxy.node.cache.bytes_total expressed in megabytes.

proxy.node.cache.contents.num_docs

Represents the number of documents currently residing in the cache.

proxy.node.cache_hit_mem_ratio_avg_10s

Represents the ratio of cache lookups over the previous 10 seconds which have been satisfied by the in-memory cache, thus avoiding disk cache I/O.

proxy.node.cache_hit_mem_ratio

Represents the ratio of cache lookups which have been satisfied by the in-memory cache since statistics collection began.

proxy.node.cache_hit_ratio_avg_10s

Represents the ratio of cache lookups over the previous 10 seconds which have been satisfied by either the in-memory cache or the disk cache, thus avoiding revalidation or object retrieval from origin servers.

proxy.node.cache_hit_ratio

Represents the ratio of cache lookups which have been satisfied by either the in-memory cache or the on-disk cache since statistics collection began.

proxy.node.cache.percent_free

Represents the percentage of allocated cache space which is not occupied by cache objects.

proxy.node.cache_total_hits_avg_10s

proxy.node.cache_total_hits

Represents the total number of cache lookups which have been satisfied by either the in-memory cache or the on-disk cache, since statistics collection began.

proxy.node.cache_total_hits_mem_avg_10s

proxy.node.cache_total_hits_mem

Represents the total number of cache lookups which have been satisfied by the in-memory cache, since statistics collection began.

proxy.node.cache_total_misses_avg_10s

proxy.node.cache_total_misses

Represents the total number of cache lookups which could not be satisfied by either the in-memory cache or the on-disk cache, and which required origin server revalidation or retrieval.
