Field Summary

Fields

Modifier and Type	Field and Description
static String	IndexCacheCapacity The capacity of the index cache.
static String	IndexCacheSize The approximate #of open indices.
static String	IndexCount The #of named indices on the live journal.
static String	IndexSegmentCacheCapacity The capacity of the IndexSegment cache.
static String	IndexSegmentCacheSize The approximate #of open IndexSegments.
static String	IndexSegmentOpenLeafByteCount The #of bytes on disk occupied by the IndexSegment leaves which are currently loaded into memory (their in-memory profile can not be directly captured by the java runtime, but you can get it from a heap dump).
static String	IndexSegmentOpenLeafCount The approximate #of IndexSegment leaves that are buffered in memory.
static String	Indices The parent under which the per-index partition performance counters are listed.
static String	StaleLocatorCacheCapacity The capacity of the cache of stale locators.
static String	StaleLocatorCacheSize The #of stale locators in the cache.
static String	StaleLocators The stale locators, including the StaleLocatorReason for each one.

Field Detail

Indices

static final String Indices

The parent under which the per-index partition performance counters are listed.

StaleLocatorCacheCapacity

static final String StaleLocatorCacheCapacity

The capacity of the cache of stale locators.

See Also:

StaleLocatorException, Constant Field Values

StaleLocatorCacheSize

static final String StaleLocatorCacheSize

The #of stale locators in the cache.

StaleLocatorException, Constant Field Values

StaleLocators

static final String StaleLocators

The stale locators, including the StaleLocatorReason for each one.

Constant Field Values

IndexCount

static final String IndexCount

The #of named indices on the live journal. Each index partition is registered as an named index on the live journal, so this may also be interpreted as the #of index partitions on the data service.

IndexCacheCapacity

static final String IndexCacheCapacity

The capacity of the index cache.

IndexCacheSize

static final String IndexCacheSize

The approximate #of open indices.

IndexSegmentCacheSize

IndexSegmentOpenLeafCount

static final String IndexSegmentOpenLeafCount

The approximate #of IndexSegment leaves that are buffered in memory.

See Also:

Constant Field Values

IndexSegmentOpenLeafByteCount

static final String IndexSegmentOpenLeafByteCount

The #of bytes on disk occupied by the IndexSegment leaves which are currently loaded into memory (their in-memory profile can not be directly captured by the java runtime, but you can get it from a heap dump). Likewise, you can directly obtain the #of bytes on disk per leaf from the IndexSegmentCheckpoint or from DumpFederation.
