Flow metrics

The Metrics page of a flow shows the amount of data (in events per second or bytes per second) processed by the flow. By default, the flow provides metrics for the input and the output of the flow. To get more information about the data flow, add Probe steps to the flow. For example, you can add a probe after:

• Select Messages steps to check the amount of data that match the filter, or
• Reduce steps to check the ratio of data saved.

The top of the page is a funnel graph that shows the amount of data (in events/sec or bytes/sec) processed at each probe of the flow. To show the funnel graph between a probe and the output, click the INPUT field on the left of the funnel graph and select a probe. That way you can display a diagram that starts at a probe (for example, after the initial Select Messages step of the flow) and shows all subsequent probes. Note that OUTPUT on the right of the funnel graph shows the relative amount of data at the output compared to the input. This value refers to the entire flow, it’s not affected by selecting a probe for the funnel graph.

The bottom part of the page shows how the amount of data processed by a probe (by default, the input probe) changed over time. Click the name of a probe on the left to show the metrics of a different probe. Click on the timeline to show the input-probe-output states corresponding to the selected timestamp. Clicking the timeline updates the funnel graph as well. You can adjust the time range in the filter bar at the top.

You can adjust the data displayed using the filter bar:

• Time period: Select the calendar_month icon to change the time period that’s displayed on the charts. You can use absolute (calendar) time, or relative time (for example, the last 2 days).

  Axoflow stores all dates in Coordinated Universal Time (UTC), and automatically converts it to the timezone of set in your browser/operating system.

• Data unit: Select the summarize icon to change the data unit displayed on the charts (events/second or bytes/second).
