Interface service graph library for go
This is a Prometheus reporter for the isg-go library. It provides functionality for tracking interface processing, and reporting the results to Prometheus in specific format.
Use go get to install the package:
go get github.com/derbylock/isg-go/isg-go-prometheus@latestFirst, initialize the PrometheusReporter:
package main
import (
"github.com/derbylock/isg-go/isg-go-lib/pkg/isg"
"github.com/derbylock/isg-go/isg-go-prometheus/pkg/promisg"
)
func main() {
ctxKeeper := isg.GetContextKeeper()
registry := prometheus.NewRegistry()
reporter := promisg.NewPrometheusReporter(ctxKeeper, time.Now, registry)
reporter.Init()
isg.SetDefaultContextKeeper(ctxKeeper)
isg.SetDefaultReporter(reporter)
}Then, use the reporter to track inbound and outbound interface processing:
package httpserverimpl
import (
"context"
"github.com/derbylock/isg-go/isg-go-lib/pkg/isg"
)
func getProductByID(ctx context.Context, id string) error {
ctx, processingCtx := isg.Inbound(ctx, "products", "app", isg.HTTP, "getProductByID")
defer processingCtx.Finish()
// process...
if err != nil {
processingCtx.Fail()
return fmt.Errorf("something wrong: %w", err)
}
return nil
