Why does my error tracker show one bug as hundreds of different errors?
Originally published at runheed.com . Error trackers group repeats of a bug by a fingerprint, usually built from the error type, the message and where it was thrown. If the message holds a value that changes each time, like a user ID, an email, a timestamp or a duration, every occurrence gets a new fingerprint. You get a new-error alert per user and a list nobody can read. If the fingerprint…
Error trackers group repeated bugs together using a fingerprint, typically constructed from the error type, message, and location. When the message includes a value that varies with each occurrence, like a user ID or timestamp, a new fingerprint is generated for each instance. This results in numerous alerts for a single bug and a list that becomes difficult to read.
To avoid this, it's recommended to remove changing values before hashing and exclude the line number from the fingerprint. By doing so, distinct bugs can be identified more clearly.
