Here is the call graph for this function:

## ◆ 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

  name | name of the observation
  duration | determines 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

  duration | determines maximum age of samples

## ◆ setMaxSampleAgeDefault()

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

Set default duration limit.

Parameters

  duration | default 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

  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
