Types ¶
type Exporter ¶
type Exporter struct {
// contains filtered or unexported fields
}
Exporter collects HAProxy stats from the given URI and exports them using the prometheus metrics package.
func NewExporter ¶
func NewExporter(opts PrometheusOptions) (*Exporter, error)
NewExporter returns an initialized Exporter. baseScrapeInterval is how often to scrape per 1000 entries (servers, backends, and frontends).
func NewPrometheusCollector ¶
func NewPrometheusCollector(opts PrometheusOptions) (*Exporter, error)
NewPrometheusCollector starts collectors for prometheus metrics from the provided HAProxy stats port. It will start goroutines. Use the default prometheus handler to access these metrics.
func (*Exporter) Collect ¶
func (e *Exporter) Collect(ch chan<- prometheus.Metric)
Collect fetches the stats from configured HAProxy location and delivers them as Prometheus metrics. It implements prometheus.Collector. It will not collect metrics more often than interval.
func (*Exporter) CollectNow ¶
func (e *Exporter) CollectNow()
CollectNow performs a collection immediately. The next Collect() will report the metrics.
func (*Exporter) Describe ¶
func (e *Exporter) Describe(ch chan<- *prometheus.Desc)
Describe describes all the metrics ever exported by the HAProxy exporter. It implements prometheus.Collector.
type PrometheusOptions ¶
type PrometheusOptions struct {
// ScrapeURI is the URI to access HAProxy under. Defaults to the unix domain socket.
ScrapeURI string
// PidFile is optional and will collect process metrics.
PidFile string
// Timeout is the maximum interval to wait for stats.
Timeout time.Duration
// BaseScrapeInterval is the minimum time to wait between stat calls per 1000 servers.
BaseScrapeInterval time.Duration
// ServerThreshold is the maximum number of servers that can be reported before switching
// to only using backend metrics. This reduces metrics load when there is a very large set
// of endpoints.
ServerThreshold int
// ExportedMetrics is a list of HAProxy stats to export.
ExportedMetrics []int
}
