Types

	Name        string `yaml:"name"`
	Description string `yaml:"description"`
	Address     string `yaml:"address"`
	Username    string `yaml:"username"`
	Password    string `yaml:"password"`
	Token       string `yaml:"token"`
}

func (*Prometheus) GetMetrics

func (p *Prometheus) GetMetrics(ctx context.Context, getMetricsRequest *prometheusProto.GetMetricsRequest) (*prometheusProto.GetMetricsResponse, error)

GetMetrics returns all metrics for all given queries. For that we are creating a map of with the selected values for all variables. Then we are looping through the list of variables, replacing the variables with the selected value and run the PromQL against the configured Prometheus instance. In the last step we transform the result, so that it can be used in the React UI.

func (*Prometheus) GetVariables

func (p *Prometheus) GetVariables(ctx context.Context, getVariablesRequest *prometheusProto.GetVariablesRequest) (*prometheusProto.GetVariablesResponse, error)

GetVariables returns all variable values. The values are label values for a Prometheus time series. The labels are retrieved via a PromQL query. To get the values we are looping over all queries and pre selecting the first value or all values, when the option is set. So we can use a variable in a following query.

func (*Prometheus) MetricLookup

func (p *Prometheus) MetricLookup(ctx context.Context, metricsLookupRequest *prometheusProto.MetricLookupRequest) (*prometheusProto.MetricLookupResponse, error)
