    • Method Detail

      • getStats

        static WindowCacheStats getStats()
        Returns:
        cache statistics for the WindowCache
        Since:
        5.1.13

      • getHitCount

        long getHitCount()
        Number of cache hits
        Returns:
        number of cache hits

      • getHitRatio

        default double getHitRatio()
        Ratio of cache requests which were hits defined as hitCount / requestCount, or 1.0 when requestCount == 0. Note that hitRate + missRate =~ 1.0.
        Returns:
        the ratio of cache requests which were hits

      • getMissCount

        long getMissCount()
        Number of cache misses.
        Returns:
        number of cash misses

      • getMissRatio

        default double getMissRatio()
        Ratio of cache requests which were misses defined as missCount / requestCount, or 0.0 when requestCount == 0. Note that hitRate + missRate =~ 1.0. Cache misses include all requests which weren't cache hits, including requests which resulted in either successful or failed loading attempts.
        Returns:
        the ratio of cache requests which were misses

      • getLoadSuccessCount

        long getLoadSuccessCount()
        Number of successful loads
        Returns:
        number of successful loads

      • getLoadFailureCount

        long getLoadFailureCount()
        Number of failed loads
        Returns:
        number of failed loads

      • getLoadFailureRatio

        default double getLoadFailureRatio()
        Ratio of cache load attempts which threw exceptions. This is defined as loadFailureCount / (loadSuccessCount + loadFailureCount), or 0.0 when loadSuccessCount + loadFailureCount == 0.
        Returns:
        the ratio of cache loading attempts which threw exceptions

      • getLoadCount

        default long getLoadCount()
        Total number of times that the cache attempted to load new values. This includes both successful load operations, as well as failed loads. This is defined as loadSuccessCount + loadFailureCount.
        Returns:
        the loadSuccessCount + loadFailureCount

      • getEvictionCount

        long getEvictionCount()
        Number of cache evictions
        Returns:
        number of evictions

      • getEvictionRatio

        default double getEvictionRatio()
        Ratio of cache evictions. This is defined as evictionCount / requestCount, or 0.0 when requestCount == 0.
        Returns:
        the ratio of cache loading attempts which threw exceptions

      • getRequestCount

        default long getRequestCount()
        Number of times the cache returned either a cached or uncached value. This is defined as hitCount + missCount.
        Returns:
        the hitCount + missCount

      • getAverageLoadTime

        default double getAverageLoadTime()
        Average time in nanoseconds for loading new values. This is totalLoadTime / (loadSuccessCount + loadFailureCount).
        Returns:
        the average time spent loading new values

      • getTotalLoadTime

        long getTotalLoadTime()
        Total time in nanoseconds the cache spent loading new values.
        Returns:
        the total number of nanoseconds the cache has spent loading new values

      • getOpenFileCount

        long getOpenFileCount()
        Number of pack files kept open by the cache
        Returns:
        number of files kept open by cache

      • getOpenByteCount

        long getOpenByteCount()
        Number of bytes cached
        Returns:
        number of bytes cached

      • getOpenByteCountPerRepository

        Map<String,​Long> getOpenByteCountPerRepository()
