Investigating large volumes of log data can be time consuming: you can spend hours on them and still understand only a fraction of them. However, application logs often look the same with some fraction of them varying. These are what we call patterns.
In the Log Explorer, patterns can be surfaced automatically to bring structure to the problem and help you quickly see what matters—exclude what’s irrelevant.
The patterns view is helpful for detecting and filtering noisy error patterns that might cause you to miss other issues. It shows the number of logs matching a pattern, split by service and status.
Switch to the patterns view to automatically see your log patterns for the selected context. A context is composed of a time range and a search query. Each pattern comes with highlights, to get you straight to its characteristic features:
Click on a pattern to see a sample of underlying logs, and eventually display one single log.
Note: The pattern detection is based on 10,000 log samples. Refine the search to see patterns limited to a specific subset of logs.
Selecting a pattern opens a contextual panel that displays a sample of underlying logs. Three buttons are available in the top-right corner:
