Cloud Logging: Finding a Needle in a Haystack of Logs

My app crashed. I had logs. Thousands of them. I needed to find the error that happened at 3:14 AM. I used to SSH into servers and grep through log files. It was slow, painful, and I usually gave up. Then I started using Cloud Logging. I can search for 'error' and get all errors. I can filter by time, by service, by severity. I can save queries. I can even create metrics from logs. When my app crashed last week, I found the error in 30 seconds. It was a null pointer in an unexpected data format. I fixed it in 10 minutes. Cloud Logging turned log analysis from a chore into a superpower. If you're still logging to files on disks, stop. Centralized logging is the only way to operate at scale.
