Detailed Description

An instance of the MetricPlugin class that sends metric data using the Channel Access protocol from EPICS.

Definition at line 32 of file epics_metric.cc.

Constructor & Destructor Documentation

artdaq::EpicsMetric::EpicsMetric	(	fhicl::ParameterSet const &	pset,
		std::string const &	app_name
	)

inlineexplicit

Construct an instance of the EpicsMetric plugin.

Parameters

pset	Parameter set to configure with. MetricPlugin parameters plus "channel_name_prefix", default "artdaq".
app_name	Name of the application sending metrics

Definition at line 64 of file epics_metric.cc.

Member Function Documentation

std::string artdaq::EpicsMetric::getLibName ( ) const

inlineoverridevirtual

Gets the unique library name of this plugin.

Returns: The library name of this plugin, "epics".

Reimplemented from artdaq::MetricPlugin.

Definition at line 78 of file epics_metric.cc.

void artdaq::EpicsMetric::sendMetric_	(	const std::string &	name,
		const std::string &	value,
		const std::string &	unit
	)

inlineoverridevirtual

Send a string metric data point to ChannelAccess.

Parameters

name	Name of the metric
value	Value of the metric
unit	Units used (not really relevant for string metrics)

Send a string metric data point to ChannelAccess. The name will be channel_name_prefix:name. If the named channel is not yet open, it will be opened. If the channel is not registered with an IOC, then the metric data will not be sent and a warning message will be printed the first time.

Implements artdaq::MetricPlugin.

Definition at line 107 of file epics_metric.cc.

void artdaq::EpicsMetric::sendMetric_	(	const std::string &	name,
		const int &	value,
		const std::string &	unit
	)

inlineoverridevirtual

Send an integer metric data point to ChannelAccess.

Parameters

name	Name of the metric
value	Value of the metric
unit	Units used

Send a string metric data point to ChannelAccess. The name will be channel_name_prefix:name. If the named channel is not yet open, it will be opened. If the channel is not registered with an IOC, then the metric data will not be sent and a warning message will be printed the first time.

Implements artdaq::MetricPlugin.

void artdaq::EpicsMetric::sendMetric_	(	const std::string &	name,
		const double &	value,
		const std::string &	unit
	)

inlineoverridevirtual

Send a double metric data point to ChannelAccess.

Parameters

name	Name of the metric
value	Value of the metric
unit	Units used

Send a string metric data point to ChannelAccess. The name will be channel_name_prefix:name. If the named channel is not yet open, it will be opened. If the channel is not registered with an IOC, then the metric data will not be sent and a warning message will be printed the first time.

Implements artdaq::MetricPlugin.

void artdaq::EpicsMetric::sendMetric_	(	const std::string &	name,
		const float &	value,
		const std::string &	unit
	)

inlineoverridevirtual

Send a float metric data point to ChannelAccess.

Parameters

name	Name of the metric
value	Value of the metric
unit	Units used

Send a string metric data point to ChannelAccess. The name will be channel_name_prefix:name. If the named channel is not yet open, it will be opened. If the channel is not registered with an IOC, then the metric data will not be sent and a warning message will be printed the first time.

void artdaq::EpicsMetric::sendMetric_	(	const std::string &	name,
		const unsigned long int &	value,
		const std::string &	unit
	)

inlineoverride

Send an unsigned integer metric data point to ChannelAccess.

Parameters

name	Name of the metric
value	Value of the metric. Will be truncated t fit in the size of a dbr_ulong_t, a 32-bit unsigned integer.
unit	Units used

Send a string metric data point to ChannelAccess. The name will be channel_name_prefix:name. If the named channel is not yet open, it will be opened. If the channel is not registered with an IOC, then the metric data will not be sent and a warning message will be printed the first time.
