Is put counted in cache stats?

[kostousov-ds]

I manually put new values to caffeine. But see 0 puts count in the cache metrics. Does this is a bug?

# HELP cache_evictions_total cache evictions
# TYPE cache_evictions_total counter
cache_evictions_total{cache="RatesCache",} 1564.0
# HELP cache_gets_total the number of times cache lookup methods have returned an uncached (newly loaded) value, or null
# TYPE cache_gets_total counter
cache_gets_total{cache="RatesCache",result="hit",} 96.0
cache_gets_total{cache="RatesCache",result="miss",} 34.0
# HELP cache_puts_total The number of entries added to the cache
# TYPE cache_puts_total counter
cache_puts_total{cache="RatesCache",} 0.0
# HELP cache_size The number of entries in this cache. This may be an approximation, depending on the type of cache.
# TYPE cache_size gauge
cache_size{cache="RatesCache",} 16266.0
# HELP cache_eviction_weight_total The sum of weights of evicted entries. This total does not include manual invalidations.
# TYPE cache_eviction_weight_total counter
cache_eviction_weight_total{cache="RatesCache",} 1564.0

Caffeine doesn’t record a put count as our minimal stats lean towards loading through the cache. This can be added on the side. If a metric is reported then you’ll need to check with whoever instrumented the cache to add that detail. See maybe #660 wrt micrometer.
