GO111MODULE=off go get github.com/andrewhodel/rrd
Run your Go program with GO111MODULE=off go run program.go
On a linux system you can run example/example.go which provides a simple example of collecting and displaying traffic statistics for an interface using a COUNTER
rrd.Rrd
type Rrd struct {
D [][]float64 `json:"d"`
R [][]float64 `json:"r"`
CurrentStep int64 `json:"currentStep"`
CurrentAvgCount int64 `json:"currentAvgCount"`
FirstUpdateTs *int64 `json:"firstUpdateTs"`
LastUpdateDataPoint []float64 `json:"lastUpdateDataPoint"`
}
rrd.Update(intervalSeconds int64, totalSteps int64, dataType string, updateDataPoint []float64, rrdPtr *Rrd)
Updates an Rrd struct via a pointer.
- intervalSeconds time between updates
- totalSteps total steps of data
- dataType GAUGE or COUNTER
GAUGE - values that stay within the range of defined integer types, like the value of raw materials.
COUNTER - values that count and can exceed the maximum of a defined integer type.
- updateDataPoint[] array of data points for the update, you must maintain the same order on following Update()'s
- rrdPtr pointer to an rrd.Rrd struct
//24 hours with 5 minute interval
rrd.Update(5*60, 24*60/5, 'GAUGE', []float64 {34, 100}, &rrdPtr);
//30 days with 1 hour interval
rrd.Update(60*60, 30*24, 'GAUGE', []float64 {34, 100}, &rrdPtr);
//365 days with 1 day interval
rrd.Update(24*60*60, 365*24, 'GAUGE', []float64 {34, 100}, &rrdPtr);
rrd.Dump(rrdPtr *Rrd)
Print the Rrd to the screen in a readable format.
The pattern gathering and detection work is in patterns/patterns.go.
