Should you use Java Agents to instrument your application?

Trade-offs around Java agent-based instrumentation

Jonatan Ivanov

If you have worked with any APMs (or other monitoring/observability products) under Java, you might have heard something like: [paraphrased-marketing-text] to track everything from performance issues to errors within your application, just attach the Java Agent to your app and all of your problems are gone [/paraphrased-marketing-text].

You can read things like this in product docs, or blog posts or hear from sales, marketing, and even in conference talks. What I think you can hear less are the trade-offs, so let’s dive a little bit into that.

How Not to Measure Elapsed Time

Jonatan Ivanov

The rabbit hole goes infinitely deep if you want to do latency measurements, benchmarking, and performance testing/tuning/analysis. They are very hard to do right and it is very easy to mess them up. In this post, I would like to show you a very common mistake (that is just 0.000001‰ of the tip of the iceberg) and an extremely simple solution to fix it.

Confusing Java Strings

I do not think it means what you think it means

Jonatan Ivanov

In this article, I would like to show you a couple of confusing things in connection with Java Strings and give you a few suggestions to avoid issues with them. I also prepared a GitHub repo for you where you can find some code that you can use to try the examples out on your own: github.com/jonatan-ivanov/java-strings-demo.
