Описание (Description)
A QmcDesc object is a container for a metric descriptor (pmDesc,
see PMAPI(3)) and units.
Конструкторы (Constructors)
~QmcDesc();
Destructor.
QmcDesc(pmID pmid);
Construct a container for the descriptor for pmid. The
descriptor is obtained from the current PMAPI(3) context
using pmLookupDesc(3).
Описание (Description)
int status() const;
A status less than zero indicates that the descriptor could
not be obtained, the PMAPI(3) error is encoded in the result.
pmID id() const;
Return the pmID for this descriptor.
pmDesc desc() const;
Return a copy of the actual metric descriptor.
const pmDesc *descPtr() const;
Return a pointer to the actual descriptor to avoid using a
pointer to a temporary.
UNITS
const QString &units() const;
The complete unit string for this descriptor.
const QString &abvUnits() const;
The unit string using abbreviations.
bool useScaleUnits() const;
Returns true if the units have been set by a call to
QmcDesc::setScaleUnits.
const pmUnits &scaleUnits() const;
Return the scaling units for this descriptor.
void setScaleUnits(const pmUnits &units);
Set the scaling units for this descriptor.
Диагностика (Diagnostic)
Error messages are generated using pmprintf(3) but are not
flushed. It is the responsibility of the user to call pmflush(3)
to output any messages.
Additional diagnostics may be activated by adding the option pmc
to the global debugging specification, as described in
pmSetDebug(3).
