Field Detail

NAME_TOKEN_DELIMITER_RGX

public static final java.lang.String NAME_TOKEN_DELIMITER_RGX

Delimiter of tokens in the metric name. Plain tokens will be retained as the CloudWatch "Metric Name".

Constant Field Values

NAME_TOKEN_DELIMITER

public static final java.lang.String NAME_TOKEN_DELIMITER

Constant Field Values

NAME_DIMENSION_SEPARATOR

public static final java.lang.String NAME_DIMENSION_SEPARATOR

Separator of key and value segments of a metric name. These segments will be split into the key and value of a CloudWatch Dimension.

Constant Field Values

NAME_PERMUTE_MARKER

public static final java.lang.String NAME_PERMUTE_MARKER

If any token, whether a simple string or a dimension pair ends with this marker, then metrics will be sent once with and once without.

VALID_DIMENSION_PART_RGX

public static final java.lang.String VALID_DIMENSION_PART_RGX

Constant Field Values

DEF_DIM_NAME_TYPE

public static final java.lang.String DEF_DIM_NAME_TYPE

Default Dimension.name for the type of metric submission, e.g. gauge, counterSum, meterSum, ...

See Also:

Constant Field Values

DEF_DIM_VAL_GAUGE

public static final java.lang.String DEF_DIM_VAL_GAUGE

Default Dimension.value for the metric type dimension added to all gauge metrics. Only numeric gauges can be reported.

See Also:

Constant Field Values

DEF_DIM_VAL_COUNTER_COUNT

public static final java.lang.String DEF_DIM_VAL_COUNTER_COUNT

Counter.getCount() returns the total of the values put in the counter. This is "counterCount" instead of just "count" or "counter" in order to search for it exclusive to "meterCount". The CloudWatch console indexes names in a way where it is beneficial that one metric identity is not a substring or subset of another metric's identity. In addition "counterCount" captures that it was a coda hale Counter, vs a Meter which includes the same Counting semantics.

Final note latter "count" is preferred to "sum" to reduce word collision when aggregating over (summing) these metrics, i.e. spoken "I am summing the counts" vs "I am summing the sums"; it's a little less confusing to use different words.

Constant Field Values

DEF_DIM_VAL_METER_COUNT

public static final java.lang.String DEF_DIM_VAL_METER_COUNT

Meter.getCount() returns the total of the values put in the counter, just like Counter.getCount().

Constant Field Values

DEF_DIM_VAL_HISTO_SAMPLES

public static final java.lang.String DEF_DIM_VAL_HISTO_SAMPLES

Histogram.getCount() returns the number of samples recorded, UNlike Counter and Meter.

Constant Field Values

DEF_DIM_VAL_HISTO_STATS

public static final java.lang.String DEF_DIM_VAL_HISTO_STATS

Histogram.getSnapshot() can be mapped into a StatisticSet. Histogram's have sliding window mechanics.

DEF_DIM_VAL_TIMER_SAMPLES

public static final java.lang.String DEF_DIM_VAL_TIMER_SAMPLES

Timer.getCount() returns the number of samples recorded, UNlike Counter and Meter.
