| typedef prom_metric_t | prom_histogram_t | 
| A prometheus histogram.  More... | |
| Functions | |
| prom_histogram_t * | prom_histogram_new (const char *name, const char *help, prom_histogram_buckets_t *buckets, size_t label_key_count, const char **label_keys) | 
| Construct a prom_histogram_t*.  More... | |
| int | prom_histogram_destroy (prom_histogram_t *self) | 
| Destroy a prom_histogram_t*.  More... | |
| int | prom_histogram_observe (prom_histogram_t *self, double value, const char **label_values) | 
| Observe the prom_histogram_t given the value and labells.  More... | |
| typedef prom_metric_t prom_histogram_t | 
| int prom_histogram_destroy | ( | prom_histogram_t * | self | ) | 
Destroy a prom_histogram_t*.
self MUSTS be set to NULL after destruction. Returns a non-zero integer value upon failure.
| prom_histogram_t* prom_histogram_new | ( | const char * | name, | 
| const char * | help, | ||
| prom_histogram_buckets_t * | buckets, | ||
| size_t | label_key_count, | ||
| const char ** | label_keys | ||
| ) | 
Construct a prom_histogram_t*.
| name | The name of the metric | 
| help | The metric description | 
| buckets | The prom_histogram_buckets_t*. See prom_histogram_buckets.h. | 
| label_key_count | is the number of labels associated with the given metric. Pass 0 if the metric does not require labels. | 
| label_keys | A collection of label keys. The number of keys MUST match the value passed as label_key_count. If no labels are required, pass NULL. Otherwise, it may be convenient to pass this value as a literal. | 
Example
// An example with labels
prom_histogram_buckets_t* buckets = prom_histogram_buckets_linear(5.0, 5.0, 10);
prom_histogram_new("foo", "foo is a counter with labels", buckets, 2, (const char**) { "one", "two" });
// An example without labels
prom_histogram_buckets_t* buckets = prom_histogram_buckets_linear(5.0, 5.0, 10);
prom_histogram_new("foo", "foo is a counter without labels", buckets, 0, NULL); 
| int prom_histogram_observe | ( | prom_histogram_t * | self, | 
| double | value, | ||
| const char ** | label_values | ||
| ) | 
Observe the prom_histogram_t given the value and labells.
| self | The target prom_histogram_t* | 
| value | The value to observe | 
| label_keys | A collection of label keys. The number of keys MUST match the value passed as label_key_count. If no labels are required, pass NULL. Otherwise, it may be convenient to pass this value as a literal. |
