Detailed Description

Computes and publishes general process metrics.

Definition at line 41 of file MetricsProcess.h.

Constructor & Destructor Documentation

MetricsProcess::MetricsProcess

(

)

Constructor.

Initializes m_last_sys and m_last_user from data gathered from SIGAR. Initializes m_last_timestamp to current time in milliseconds.

Definition at line 39 of file MetricsProcess.cc.

Member Function Documentation

void MetricsProcess::collect ( int64_t  now, MetricsCollector *  collector  )

overridevirtual

Collects process metrics.

Computes process metrics and publishes them via collector. The following JVM metrics and process metrics collected from SIGAR are computed and published:

• cpu.sys - CPU system time (%)
• cpu.user - CPU user time (%)
• memory.virtual - Virtual memory (GB)
• memory.resident - Resident memory (GB)
• memory.heap - Heap size (GB)
• memory.heapSlack - Heap slack bytes (GB)
• version - Hypertable version string

Parameters

now	Current time in nanoseconds
collector	Metrics collector

Implements Hypertable::Metrics.

Definition at line 47 of file MetricsProcess.cc.
