Monitor CPU and Memory Usage of External Services Accessed by your Go Application

The performance and reliability of external services your Go application depends on play a crucial role in ensuring the overall efficiency and user experience. Monitoring the CPU and memory usage of these external services is vital to identify potential bottlenecks, resource constraints, and possible points of failure that could impact your application’s performance.

Saashound, a powerful real-time event tracking tool, offers a comprehensive solution for monitoring the CPU and memory usage of external services accessed by your Go application. By integrating Saashound directly into your application, you can gain valuable insights into the performance of external services, set up custom alerts for critical thresholds, and take proactive measures to optimize your application’s interactions with these services.

The Importance of Monitoring External Services

Your Go application often relies on various external services, such as databases, APIs, and third-party platforms. Monitoring the CPU and memory usage of these external services is crucial for the following reasons:

1. Performance Optimization: Tracking resource utilization helps identify performance bottlenecks and optimize interactions with external services for faster response times.

2. Service Reliability: Monitoring CPU and memory usage allows you to detect potential service overloads or resource constraints that could impact reliability.

3. Resource Management: Efficient resource utilization helps ensure optimal utilization of resources, reducing operational costs and improving scalability.

Connecting Saashound to Your Go Application

To start monitoring CPU and memory usage of external services accessed by your Go application using Saashound, follow these simple steps:

1. Sign up for a free Saashound account to begin tracking your application’s events.
2. Create your first project from the intuitive dashboard.
3. Access the settings and securely copy your unique API token.

Go Integration for Monitoring External Services

Integrating Saashound into your Go application to monitor external services is straightforward. Use the following code snippet to track CPU and memory usage events. Replace API_TOKEN with your actual Saashound API token and update the project name to match your project.

package main

import (
  "bytes"
  "encoding/json"
  "fmt"
  "net/http"
)

func logEvent() {
  apiURL := "https://api.saashound.co/log-event"
  payload := map[string]interface{}{
    "project":     "my-second-proect",
    "channel":     "server-status",
    "event":       "High CPU Usage",
    "description": "CPU for my-second-project has been over 95% for 1 Hour!.",
    "icon":        "🔥",
    "notify":      true
  }

  payloadBytes, err := json.Marshal(payload)
  if err != nil {
    fmt.Println("Error marshaling payload:", err)
    return
  }

  req, err := http.NewRequest("POST", apiURL, bytes.NewReader(payloadBytes))
  if err != nil {
    fmt.Println("Error creating request:", err)
    return
  }

  req.Header.Set("Content-Type", "application/json")
  req.Header.Set("Authorization", "Bearer API_TOKEN")

  client := http.DefaultClient
  resp, err := client.Do(req)
  if err != nil {
    fmt.Println("Error sending request:", err)
    return
  }
  defer resp.Body.Close()

  if resp.StatusCode >= 200 && resp.StatusCode < 300 {
    fmt.Println("Log event sent successfully!")
  } else {
    fmt.Println("Failed to send log event. Response code:", resp.StatusCode)
  }
}

func main() {
  logEvent()
}
