◆ getMaxSampleAgeDefault()

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

Get default duration limit.

Returns
default maximum age of samples to keep.

Definition at line 217 of file lib/stats/stats_mgr.cc.

◆ getMaxSampleCountDefault()

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 228 of file lib/stats/stats_mgr.cc.

◆ setMaxSampleAge()

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
namename of the observation
durationdetermines maximum age of samples
Returns
true if successful, false if there's no such statistic

◆ setMaxSampleAgeAll()

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

Set duration limit for all collected statistics.

Parameters
durationdetermines maximum age of samples

◆ setMaxSampleAgeDefault()

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

Set default duration limit.

Parameters
durationdefault maximum age of samples to keep

◆ setMaxSampleCount()

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
namename of the observation
max_sampleshow many samples of a given statistic should be kept
Returns
true if successful, false if there's no such statistic

Parameters
max_sampleshow many samples of a given statistic should be kept

◆ setMaxSampleCountDefault()

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

Set default count limit.

Parameters
