Function Documentation

◆ addValue() [1/4]

void isc::stats::StatsMgr::addValue	(	const std::string &	name,
		const int64_t	value
	)

Records incremental integer observation.

Parameters

name	name of the observation
value	integer value observed

Exceptions

InvalidStatType if statistic is not integer

Definition at line 46 of file stats_mgr.cc.

References isc::stats::StatsMgr::addValueInternal().

Referenced by isc::ha::HAImpl::buffer4Receive(), isc::ha::HAImpl::buffer6Receive(), isc::dhcp::Dhcpv4Srv::processPacket(), isc::dhcp::Dhcpv4Srv::processStatsReceived(), and isc::dhcp::Dhcpv4Srv::processStatsSent().

Here is the call graph for this function:

◆ addValue() [2/4]

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

Records incremental floating point observation.

Parameters

name	name of the observation
value	floating point value observed

Exceptions

InvalidStatType if statistic is not fp

Definition at line 50 of file stats_mgr.cc.

References isc::stats::StatsMgr::addValueInternal().

Here is the call graph for this function:

◆ addValue() [3/4]

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

Definition at line 54 of file stats_mgr.cc.

References isc::stats::StatsMgr::addValueInternal().

Here is the call graph for this function:

◆ addValue() [4/4]

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

Records incremental string observation.

Parameters

name	name of the observation
value	string value observed

Exceptions

InvalidStatType if statistic is not a string

Definition at line 58 of file stats_mgr.cc.

References isc::stats::StatsMgr::addValueInternal().

Here is the call graph for this function:

◆ setMaxSampleAge()

void 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.

Todo:: : Not implemented.

Example: to set a statistic to keep observations for the last 5 minutes, call setMaxSampleAge("incoming-packets", time_duration(0,5,0,0)); to revert statistic to a single value, call: setMaxSampleAge("incoming-packets" time_duration(0,0,0,0))

Definition at line 80 of file stats_mgr.cc.

References isc_throw.

◆ setMaxSampleCount()

void 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.

Todo:: : Not implemented.

Example: To set a statistic to keep the last 100 observations, call: setMaxSampleCount("incoming-packets", 100);

◆ setValue() [1/4]

void isc::stats::StatsMgr::setValue	(	const std::string &	name,
		const int64_t	value
	)

Records absolute integer observation.

Parameters

value	integer value observed

Exceptions
