The MetricPlugin class defines the interface that MetricManager uses to send metric data to the vario...
void sendMetric_(const std::string &name, const std::string &value, const std::string &, const std::chrono::system_clock::time_point &) override
Set the value to be written to the pipe when it is opened by a reader.
void startMetrics()
Perform startup actions. Simply calls the virtual startMetrics_ function.
std::string getLibName() const override
Get the "library name" of this Metric.
void stopMetrics_() override
Open the pipe for reading to allow the metric-sending thread to end gracefully.
fhicl::ParameterSet pset
The ParameterSet used to configure the MetricPlugin.
void startMetrics_() override
Start the metric-sending thread.
void writePipe()
Wait for the pipe to be opened and then write the current value to it.
void stopMetrics()
Perform shutdown actions. Zeroes out all accumulators, and sends zeros for each metric. Calls stopMetrics_() for any plugin-defined shutdown actions.
void sendMetric_(const std::string &name, const int &value, const std::string &unit, const std::chrono::system_clock::time_point &time) override
Set the value to be written to the pipe when it is opened by a reader.
~ProcFileMetric() override
ProcFileMetric Destructor.
ProcFileMetric(fhicl::ParameterSet const &config, std::string const &app_name, std::string const &metric_name)
ProcFileMetric Constructor.
void sendMetric_(const std::string &name, const uint64_t &value, const std::string &unit, const std::chrono::system_clock::time_point &time) override
Set the value to be written to the pipe when it is opened by a reader.
void sendMetric_(const std::string &name, const float &value, const std::string &unit, const std::chrono::system_clock::time_point &time) override
Set the value to be written to the pipe when it is opened by a reader.
void sendMetric_(const std::string &name, const double &value, const std::string &unit, const std::chrono::system_clock::time_point &time) override
Set the value to be written to the pipe when it is opened by a reader.
A MetricPlugin which writes a long unsigned int metric with a given name to a given pipe...
