Webhook Monitoring Guide
Monitoring webhooks can be a real challenge. You have to understand what data to collect, how to collect it, and what metrics to track.
If you gather too much data, you could can lose the signal in the noise. Collect bad data and your insights are unreliable.
To make sure your monitoring efforts yield actionable metrics, you should first solidify the reasons why we want to monitor our webhook system. What can go wrong and how can we identify the problem?
The goal of status monitoring is to provide instant feedback on how a system is functioning at any given moment. If a user is experiencing an issue, they need to know if their endpoint is failing or if the webhook service is down.
Because webhook systems have several components, you'll want to provide status information for the entire system as well as for specific components to make it easier to diagnose any issues.
Availability monitoring is similar to status monitoring with a couple key differences. First, the motivation behind status monitoring is to provide the current status of the system while the motivation for availability monitoring is to understand the reliability of the system over time.
This helps you monitor infrastructure usage to prevent problems from arising and you can focus on other important but less time-consuming tasks.
This is why you should record timestamps of any data related to the cause of any availability issues.
Not only does your usage steadily increase over time, some users can have dramatic spikes in usage that your system will need to respond to.
As volume increases, our system needs to process more webhooks and collect more data. This can put strain on our infrastructure, increasing the chances of something going wrong.
In order to keep track of system performance and ensure that you avoid a substantial drop in performance, you need to define some key metrics which will serve as a benchmark for the webhook infrastructure's expected throughput. This way you'll be able to identify any slow downs early and resolve any bottlenecks/problems before your system slows to a crawl.
While these are key baseline components of a webhook monitoring system, you will probably find that there are other key items to track based on your specific implementation and use case. Just make sure you're clearly defining the problem and how you're going to identify it.
