// MetricFamilyToOpenMetrics converts a MetricFamily proto message into the
|
||||
// OpenMetrics text format and writes the resulting lines to 'out'. It returns
|
||||
// the number of bytes written and any error encountered. The output will have
|
||||
// the same order as the input, no further sorting is performed. Furthermore,
|
||||
// this function assumes the input is already sanitized and does not perform any
|
||||
// sanity checks. If the input contains duplicate metrics or invalid metric or
|
||||
// label names, the conversion will result in invalid text format output.
|
||||
//
|
||||
// This function fulfills the type 'expfmt.encoder'.
|
||||
//
|
||||
// Note that OpenMetrics requires a final `# EOF` line. Since this function acts
|
||||
// on individual metric families, it is the responsibility of the caller to
|
||||
// append this line to 'out' once all metric families have been written.
|
||||
// Conveniently, this can be done by calling FinalizeOpenMetrics.
|
||||
//
|
||||
// The output should be fully OpenMetrics compliant. However, there are a few
|
||||
// missing features and peculiarities to avoid complications when switching from
|
||||
// Prometheus to OpenMetrics or vice versa:
|
||||
//
|
||||
// - Counters are expected to have the `_total` suffix in their metric name. In
|
||||
// the output, the suffix will be truncated from the `# TYPE` and `# HELP`
|
||||
// line. A counter with a missing `_total` suffix is not an error. However,
|
||||
// its type will be set to `unknown` in that case to avoid invalid OpenMetrics
|
||||
// output.
|
||||
//
|
||||
// - No support for the following (optional) features: `# UNIT` line, `_created`
|
||||
// line, info type, stateset type, gaugehistogram type.
|
||||
//
|
||||
// - The size of exemplar labels is not checked (i.e. it's possible to create
|
||||
// exemplars that are larger than allowed by the OpenMetrics specification).
|
||||
//
|
||||
// - The value of Counters is not checked. (OpenMetrics doesn't allow counters
|
||||
// with a `NaN` value.)
