View Log Data by Timeline
The Mezmo Timeline is a tool for seeing patterns and trends in log lines over time. By default, it shows the most recent 60 minutes of log lines.
Use the timeline to:
- View the counts of logs that match a specific query to understand how often the same action is occurring in a timeframe.
- Debug issues that occurred during a specific timeframe to do root cause analysis.
- Determine exactly when a certain error first started occurring.
Access the timeline by selecting Views.

You can continue to scope until you get to the time you want to view. Each bar represents 15 minutes.
You can not use the Time scale selector to zoom in further than your current time frame selection.
Compare Time Scale
Once you have scoped in on the time scale, you can investigate and compare times before and after. For example, the original time you zoomed in on was 10 minutes. Then you selected 30 minutes in the time scale drop down. You will see log lines for:
