Embarrassingly, gauge was misspelled for quite some time.

Meters are non-standard and poorly supported by StatsD servers

void ast_statsd_log_full | ( | const char * | metric_name, |

) |
Send a stat to the configured statsd server.
The is nearly the most flexible function for sending a message to the statsd server, but also the least easy to use. See ast_statsd_log() or ast_statsd_log_sample() for a slightly more convenient interface.
metric_name | String (UTF-8) name of the metric. |
metric_type | Type of metric to send. |
value | Value to send. |
sample_rate | Percentage of samples to send. |

const char * | metric_type, | ||
intmax_t | value, | ||
double | sample_rate, | ||
... | |||
) |
Send a stat to the configured statsd server.
This is the most flexible function for sending a message to the statsd server. In addition to allowing the value and sample rate to be specified, the metric_name can be formed as a printf style string with variable arguments.
metric_name | Format string (UTF-8) specifying the name of the metric. |
metric_type | Type of metric to send. |
value | Value to send. |
sample_rate | Percentage of samples to send. |

void ast_statsd_log_sample | ( | const char * | metric_name, |
intmax_t | value, | ||
double | sample_rate | ||
) |
Send a random sampling of a stat to the configured statsd server.
The type of sampled metrics is always AST_STATSD_COUNTER. The given sample_rate should be a percentage between 0.0 and 1.0. If it's <= 0.0, then no samples will be sent. If it's >= 1.0, then all samples will be sent.
metric_name | String (UTF-8) name of the metric. |
value | Value to send. |
sample_rate | Percentage of samples to send. |

void ast_statsd_log_string | ( | const char * | metric_name, |
const char * | metric_type, | ||
const char * | value, | ||
double | sample_rate | ||
) |
Send a stat to the configured statsd server.
This function uses a character argument for value instead of an intmax_t argument. This is designed to be simpler to use for updating a current value rather than resetting it.
metric_name | String (UTF-8) name of the metric. |
metric_type | Type of metric to send. |
value | Value to send. |
sample_rate | Percentage of samples to send. |
