	)

Records incremental floating point observation.

Parameters

name	name of the observation
value	floating point value observed

Exceptions

InvalidStatType if statistic is not fp

Here is the call graph for this function:

void isc::stats::StatsMgr::addValue	(	const std::string &	name,
		const StatsDuration &	value
	)

Records incremental duration observation.

Parameters

name	name of the observation
value	duration value observed

Exceptions

InvalidStatType if statistic is not time duration

void isc::stats::StatsMgr::addValue	(	const std::string &	name,
		const std::string &	value
	)

Parameters

value	string value observed

Exceptions

Here is the call graph for this function:

const StatsDuration & isc::stats::StatsMgr::getMaxSampleAgeDefault ( ) const

Get default duration limit.

Returns: default maximum age of samples to keep.

Definition at line 270 of file lib/stats/stats_mgr.cc.

uint32_t isc::stats::StatsMgr::getMaxSampleCountDefault ( ) const

Get default count limit.

Returns: default maximum number of samples to keep. (0 means that count limit was disabled)

Definition at line 285 of file lib/stats/stats_mgr.cc.

bool isc::stats::StatsMgr::setMaxSampleAge	(	const std::string &	name,
		const StatsDuration &	duration
	)

Determines maximum age of samples.

Specifies that statistic name should be stored not as a single value, but rather as a set of values. duration determines the timespan. Samples older than duration will be discarded. This is time-constrained approach. For sample count constrained approach, see setMaxSampleCount() below. Example: To set a statistic to keep observations for the last 5 minutes, call: setMaxSampleAge("incoming-packets", StatsDuration::minutes(5)); to revert statistic to a single value, call: setMaxSampleAge("incoming-packets", StatsDuration:zero());

Parameters

name	name of the observation
duration	determines maximum age of samples

Returns: true if successful, false if there's no such statistic

void isc::stats::StatsMgr::setMaxSampleAgeAll ( const StatsDuration & duration )

Set duration limit for all collected statistics.

Parameters

duration determines maximum age of samples

void isc::stats::StatsMgr::setMaxSampleAgeDefault ( const StatsDuration & duration )

Set default duration limit.

Parameters

duration default maximum age of samples to keep

bool isc::stats::StatsMgr::setMaxSampleCount	(	const std::string &	name,
		uint32_t	max_samples
	)

Determines how many samples of a given statistic should be kept.

Specifies that statistic name should be stored not as single value, but rather as a set of values. In this form, at most max_samples will be kept. When adding max_samples + 1 sample, the oldest sample will be discarded. Example: To set a statistic to keep the last 100 observations, call: setMaxSampleCount("incoming-packets", 100);

Parameters

name	name of the observation
max_samples	how many samples of a given statistic should be kept

Returns: true if successful, false if there's no such statistic

void isc::stats::StatsMgr::setMaxSampleCountAll ( uint32_t max_samples )

Parameters

Definition at line 225 of file lib/stats/stats_mgr.cc.

Referenced by isc::dhcp::SrvConfig::updateStatistics().

void isc::stats::StatsMgr::setMaxSampleCountDefault ( uint32_t max_samples )

Set default count limit.

Parameters
