Typedef Documentation

pms_t

typedef struct pms pms_t

Contains the specific metric and value given the name and label set.

Note

All operations MUST be called on a sample derived from a gauge metric. Reference: https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels

Function Documentation

pms_add()

int pms_add	(	pms_t *	self,
		double	r_value
	)

Add the given r_value to the given sample.

Parameters

self	Where to add the given value.
r_value	Value to add. Must be >= 0.

Returns

Non-zero integer value upon failure, 0 otherwise.

pms_set()

int pms_set	(	pms_t *	self,
		double	r_value
	)

Set the given r_value to the given ample.

Parameters

self	Where to set the given value.
r_value	Value to set.

Returns

Non-zero integer value upon failure, 0 otherwise.

pms_sub()

int pms_sub	(	pms_t *	self,
		double	r_value
	)

Subtract the given r_value from the given sample.

Parameters

self	Where to add the given value.
r_value	Value to substract.

Returns

Non-zero integer value upon failure, 0 otherwise.
