Yeller is a
Java Exception Tracker
Shipping bugs really sucks
These bugs made it past your test suite, past your reasoning about the system, past your careful manual checking and into your customers' hands.
So, once you know about a bug, you need to fix it as fast as possible. This means you need to find out exactly what happened, with all the useful and relevant information at your fingertips.
Yeller is built on the JVM, so it fully understands Java exceptions. It's built on top of distributed systems, there's no single point of failure in it's architecture, and the 99th percentile on the api handler is a screaming 4ms.
Track your Exceptions
Yeller tracks the exceptions your customers hit in production so you can fix them faster.
Yeller's Java client is fully open source, and there are detailed install instructions in the repository
// make a client
YellerClient yellerClient = new YellerClient('YOUR_API_KEY_HERE');
//Report your own exception
try {
// Your code here
} catch (Throwable t) {
yellerClient.report(t);
throw t;
}
All the details
Yeller grabs all the relevant context from your exceptions, so you can figure out what went wrong quickly.
- The full type and error message
- The full stacktrace - nothing trimmed here
- Full context from the place the error happened (for HTTP requests, this includes params, cookies, and so on. For background jobs, this might include the job parameters)
Automatic Diagnosis
Yeller automatically investigates each of your exceptions across every time they happen, and picks out any unique piece of context
Find out about exceptions that were:
- Caused by one of your servers behaving badly
- Isolated to an individual customer
- Or any other piece of data you can think of
Suspect deploy
Most exceptions in production are caused by code changes.
Yeller can track your deploys, and highlight the deploy that likely caused the exception you're debugging.
If you use github, Yeller will even link to a diff of what was deployed, so you can see what changed immediately.
