This annotation interface describes the parameters required when defining a benchmark driver.

Optional Element Summary

String	metric The default metric is "ops/sec".
String	name The driver's name, can be ignored for a single-driver benchmark.
String	opsUnit Unit of operation, in plural.
String[]	percentiles The percentiles to measure against.
TimeUnit	responseTimeUnit The time unit used for reporting response times.
float	threadPerScale The number of threads this driver should launch for each benchmark scale.

name

public abstract String name

The driver's name, can be ignored for a single-driver benchmark.

Default:

""

metric

public abstract String metric

The default metric is "ops/sec". Otherwise specify.

Default:

"ops/sec"

opsUnit

public abstract String opsUnit

Unit of operation, in plural.

Default:

"operations"

threadPerScale

public abstract float threadPerScale

The number of threads this driver should launch for each benchmark scale. The actual number of threads launched for this driver is a round(threadsPerScale x scale).

Default:

1.0f

percentiles

public abstract String[] percentiles

The percentiles to measure against. Overrides 90th% setting (old style). The percentiles must be numeric strings representing the percentiles of interest. The number must be greater than 0 and less than 100. Decimal digits can be used. The number may optionally have a suffix of 'th', 'st', 'nd', or 'rd' which will be used in the reporting. It can also end with the '%' sign. The following are valid percentiles.

• 99
• 99th
• 99th%
• 99.99
• 99.99th
• 99.99th%

Default:

{}

responseTimeUnit

public abstract TimeUnit responseTimeUnit

The time unit used for reporting response times.

Default:

java.util.concurrent.TimeUnit.SECONDS
