Instrumenting Your Apps with Metrics

One of the most powerful things you can do in monitoring is also one of the most overlooked things: instrumenting your own applications. Why would you want to do this? Easy: your apps have a ton of valuable information about their performance, many of which will allow you to move from reactive to proactive in maintaining that performance.

One common fear I’ve heard is that it’s difficult and time-consuming to add metrics to apps, but I’m here to tell you neither are true. As with all things, starting simple is the key: what about timing how long database queries take? Or how long some external vendor API takes to respond? Or how many logins happen throughout the day?

Once you start instrumenting your app, it becomes addictive. App metrics are so useful for a variety of things, you’ll wonder why you didn’t get started sooner.
