Monitor high disk usage in your Go application

When building Go applications, we often end up dealing with persistent data in one way or another. This can be a simple JSON, CSV, or text file on disk, uploading files to cloud storage such as S3 or Google Cloud Storage, or even storing data in a database such as MongoDB or MySQL. In all of these cases, disk usage is a critical aspect of our Go application and can significantly affect the user experience.

Therefore, monitoring our Go application's disk usage is essential, whether in the local environment or somewhere in the cloud. This is critical as going over a certain threshold can cause our application to crash or become unavailable, resulting in a significant loss of revenue and user experience.

LogSnag is a powerful event tracking tool that works seamlessly with Go and makes it trivial to track any important event in our Go application in real time. For example, one common use case for LogSnag is tracking disk usage in real-time and setting up rules to notify our team and us when our disk usage has exceeded a certain threshold. This way, we can always be aware of the performance of our application and take immediate action if needed.

Setting up LogSnag

1. Sign up for a free LogSnag account.
2. Create your first project from the dashboard.
3. Head to settings and copy your API token.

Go code snippets

Use the following code to connect LogSnag to your Go application and track disk usage: Please replace the YOUR_API_TOKEN with your API token and update the project and channel names.

package main

import (
  "fmt"
  "strings"
  "net/http"
  "io/ioutil"
)

func main() {

  url := "https://api.logsnag.com/v1/log"
  method := "POST"

  payload := strings.NewReader(`{"project":"my-saas","channel":"status","event":"High Disk Usage","description":"The disk usage is high.","icon":"💾","notify":true}`)

  client := &http.Client {
  }
  req, err := http.NewRequest(method, url, payload)

  if err != nil {
    fmt.Println(err)
    return
  }
  req.Header.Add("Content-Type", "application/json")
  req.Header.Add("Authorization", "Bearer YOUR_API_TOKEN")

  res, err := client.Do(req)
  if err != nil {
    fmt.Println(err)
    return
  }
  defer res.Body.Close()

  body, err := ioutil.ReadAll(res.Body)
  if err != nil {
    fmt.Println(err)
    return
  }
  fmt.Println(string(body))
}
