Log Trigger LTS

You can write FunctionGraph functions to process logs subscribed to Cloud Log Service. When Cloud Log Service collects subscribed logs, you can call FunctionGraph functions by passing the collected logs as parameters (LTS sample events). FunctionGraph function code can be customized, analyzed, or loaded into other systems. For the use of LTS log triggers, please refer to Using a LTS Trigger.

Example LTS Event

{
  "lts": {
    "data": "=="
  }
}

Parameter description

Parameter	Type	Example Value	Description

Example

handler.go

package main

import (
	"encoding/json"
	"fmt"

	"github.com/opentelekomcloud-community/otc-functiongraph-go-runtime/go-runtime/events/lts"
	"github.com/opentelekomcloud-community/otc-functiongraph-go-runtime/go-runtime/go-api/context"
	"github.com/opentelekomcloud-community/otc-functiongraph-go-runtime/go-runtime/pkg/runtime"
)

// Example for Log Tank Service handler
func LtsTest(payload []byte, ctx context.RuntimeContext) (interface{}, error) {
	var ltsEvent lts.LTSTriggerEvent
	err := json.Unmarshal(payload, &ltsEvent)
	if err != nil {
		fmt.Println("Unmarshal failed")
		return "invalid data", err
	}
	ctx.GetLogger().Logf("payload:%s", ltsEvent.String())
	return "ok", nil
}

func main() {
	runtime.Register(LtsTest)
}
