Webhook monitoring helps ensure your system is working correctly. It gives you an understanding of the health of your webhooks. This article will cover different kinds of webhook tracking and how to implement them in your system. To follow this article, sign up for a free trial of MetricFire.

What Is A Webhook?

Webhooks allow APIs to communicate with each other based on real-time events. They are so similar to APIs that they can sometimes be confused with APIs. 

Occasionally, you hear them called event-based APIS. Rather than keeping an open stream of back-and-forth data, webhooks must be triggered before sending or receiving data.

Why Monitor Webhooks?

When you monitor your webhooks, you get a bigger picture of whether your system works properly, what can be fixed, etc. 

It’s safe to assume that if you have a webhook system, you should be monitoring it. But the reasons may depend on your goals. We’ll look deeper at the different types of webhook monitoring below.


Types of Performance Stats to Monitor

Monitoring webhooks is critical to understanding the health and performance of your system. But monitoring is meaningless if you don’t have goals. Goals are outlines for the types of metrics you want to collect. Here are some favorite metrics for webhook monitoring:


  1. Response Time or latency measures the time it takes for a webhook endpoint to respond to a request.

  2. Success Rate is the percentage of successful webhook deliveries compared to the total number of attempts. A high success rate indicates a reliable system.

  3. The Failure Rate is the percentage of failed webhook deliveries compared to the total number of attempts. Stats on failure rates help identify potential issues in the system.

  4. Error Rate shows errors by HTTP status codes (e.g., 4xx and 5xx errors). This helps pinpoint the types of errors occurring.

  5. Retry Rate is the frequency of webhook retries due to initial delivery failures. High retry rates indicate initial delivery or endpoint stability issues.

  6. Time to First Byte measures the time the webhook endpoint takes to send the response after the request is made.

  7. Throughput is the number of webhook requests processed per second. It helps understand the webhook system's capacity and scalability.

  8. Queue Size is the number of pending webhook deliveries in the queue. Large queue sizes indicate bottlenecks or processing delays.

  9. Delivery Duration measures the time from initiating the webhook request to receiving a complete response. This includes both response time and any processing time at the endpoint.

  10. Payload Size is the size of the data being sent in the webhook request. Monitoring payload sizes can help optimize data transfer and ensure efficient processing.

Top 3 Ways to Collect and Store Webhook Performance Metrics:

Once you know what metrics you need, the next step is collecting them. Here are three ways to do that:

  1. Logging and Log Analysis: DevOps engineers can collect webhook performance metrics by capturing detailed logs of webhook requests and responses. This includes logging timestamps, response times, status codes, payload sizes, and error messages.

  2. Monitoring with APM Tools: Application Performance Monitoring (APM) tools can capture detailed performance metrics of webhook operations. APM tools provide insights into request durations, throughput, error rates, and resource usage.

  3. Custom Metrics Collection with Monitoring Agents: DevOps engineers can use monitoring agents to collect custom metrics specifically tailored to webhook performance. This involves instrumenting code to record metrics like request processing time, success/failure counts, and payload statistics.

These methods ensure that webhook performance is continuously monitored. This enables quick issue detection and resolution, ultimately improving reliability and user experience.


Using MetricFire to Monitor Webhook Metrics

We highly recommend monitoring webhooks with our platform, Hosted Graphite. You can quickly get started by signing up for a free trial! Here is an overview of how to monitor with Hosted Graphite:

  1. Instrumenting the Code:

    1. Metric Collection: Add custom code in your webhook handler to track metrics like request processing times, response statuses, and error rates.

    2. StatsD Integration: A StatsD client sends these metrics to Hosted Graphite.

  2. Sending Metrics:

    1. StatsD Protocol: Configure your StatsD client with Hosted Graphite's endpoint and API key to send metrics.

    2. Telegraf Agent: Alternatively, use the Telegraf agent to collect metrics and forward them to Hosted Graphite. Telegraf can gather data from various sources and send it to Graphite.

  3. Storing Metrics:

    1. Time-Series Database: Hosted Graphite stores metrics in a time-series database optimized for high-performance storage and retrieval.

    2. Retention and Aggregation: Hosted Graphite rolls your data into several resolutions and stores it for defined periods. It stores 5-second data for one day, 30-second data for three days, five-minute data for six months, and one-hour data for two years.

  4. Visualizing and Monitoring

    1. Dashboards: Use MetricFire's Hosted Grafana dashboards to visualize webhook performance metrics, such as response times, success/error rates, and payload sizes.

    2. Alerts and Notifications: Configure Graphite alerts to notify you of anomalies or performance issues via email, Slack, PagerDuty, etc.

You can monitor webhooks by using custom code, StatsD, or Telegraf to collect metrics, Hosted Graphite for storage, and Grafana for visualization. This setup provides real-time monitoring, historical analysis, and proactive alerting to ensure webhook reliability and efficiency.
