Hello,
I have a requirement to create a datadog dashboard with application
metrics. The app names are read from a config.toml. The code runs only for
the first app provided in the toml file and never proceeds to the second
app. The structure is a follows:
*config.toml*
application = ["app1", "app2", "app3"]
customer = ["abc"]
*main.go*
// Sending Metrics to Datadog UI
func sendMetrics(name string, channel chan string) {
// Calculates the Epoch Time for App
EpochTime1 := epochTime()
// Calculates the Epoch Time for Github
EpochTime2 := gitEpochTime()
// Lead Time from Github Commit to App Deployment
calculated_time := EpochTime1 - EpochTime2
v := versionDetails()
dd_tags := "metric_tag:" + v
tags := []string{dd_tags}
rate := float64(1)
c, err := statsd.New("127.0.0.1:18125")
if err != nil {
log.Fatal(err)
}
e := c.Gauge(name, float64(calculated_time), tags, rate)
if e != nil {
log.Println(e)
fmt.Println("name:::", name)
fmt.Println("lead time:::", leadTime)
channel <- name
}
fmt.Println("name:::", name)
fmt.Println("lead time:::", leadTime)
channel <- name
log.Printf("Metrics for %s sent successfully!!", name)
}
func main() {
channel := make(chan string)
appName, _ := getTag() //gets the appName and customerName both of which
are [] string type
fmt.Println("App names: ", appName, reflect.TypeOf(appName))
for _, app := range appName {
// Calculate the Epoch Time
fmt.Println("Executing app............ ", app)
if epochTime() == 0 {
log.Println("No deployment present during the Time Frame!")
for res := range channel {
go func(app string) {
time.Sleep(3 * time.Second)
sendMetrics(app, channel)
}(res)
}
} else {
go sendMetrics(app, channel)
for res := range channel {
go func(name string) {
time.Sleep(3 * time.Second)
sendMetrics(name, channel)
}(res)
}
}
}
}
I am new to Golang and any help is highly appreciated.
Thanks,
Shatabdi
