Functions ¶
func ExternalLabels ¶
ExternalLabels returns external labels from /api/v1/status/config Prometheus endpoint. Note that configuration can be hot reloadable on Prometheus, so this config might change in runtime.
func IsWALDirAccesible ¶
IsWALFileAccesible returns no error if WAL dir can be found. This helps to tell if we have access to Prometheus TSDB directory.
func PromqlQueryInstant ¶
func PromqlQueryInstant(ctx context.Context, logger log.Logger, base *url.URL, query string, t time.Time, dedup bool) (promql.Vector, error)
PromqlQueryInstant performs instant query and returns results in promql.Vector type that is compatible with promql package.
func QueryInstant ¶
func QueryInstant(ctx context.Context, logger log.Logger, base *url.URL, query string, t time.Time, dedup bool) (model.Vector, error)
QueryInstant performs instant query and returns results in model.Vector type.
func Snapshot ¶
Snapshot will request Prometheus to perform snapshot in directory returned by this function. Returned directory is relative to Prometheus data-dir. NOTE: `--web.enable-admin-api` flag has to be set on Prometheus. Added to Prometheus from v2.1. TODO(bwplotka): Add metrics.
Types ¶
type Flags ¶
type Flags struct {
TSDBPath string `json:"storage.tsdb.path"`
TSDBRetention model.Duration `json:"storage.tsdb.retention"`
TSDBMinTime model.Duration `json:"storage.tsdb.min-block-duration"`
TSDBMaxTime model.Duration `json:"storage.tsdb.max-block-duration"`
WebEnableAdminAPI bool `json:"web.enable-admin-api"`
WebEnableLifecycle bool `json:"web.enable-lifecycle"`
}
func ConfiguredFlags ¶
ConfiguredFlags returns configured flags from /api/v1/status/flags Prometheus endpoint. Added to Prometheus from v2.2.
