Metrics
Click Metrics in the Monitor navigation menu and select a Snaplex node to view graphs of key indicators. Use the metrics to:
- Analyze the behavior of a Snaplex node.
- Improve task scheduling by finding under- and over-utilized time periods.
- Troubleshoot performance issues by identifying usage spikes.
- View trends and individual data points.
- Zoom in on charts to focus on a shorter time period.
- Expand a chart to determine which pipelines ran at a specific time and to view the execution details.
- Review Snap statistics, pipeline logs, and pipeline parameters.
- Download files for:
- Graph values in JSON format
- Pipeline logs in JSON format
- Runtime details in CSV format
As shown in the screenshot below, hover on a data point to view the values. The data point synchronizes in all graphs. Refer to Graph descriptions for more details on chart metrics.
The scale of charts depends on the time period you select:
- For seven days or less, each data point represents the average value of that metric in one-minute intervals.
- For more than seven days, each data point represents the average value of that metric over fifteen-minute intervals.
The following table describes the actions available from the Metrics page toolbar, the graph in the default layout, and an expanded graph:
| From the page toolbar: | From the default charts layout: | From an expanded chart: |
|---|---|---|

| Change the time period | Download graph data | Download graph data |
| Refresh graph data | View individual data point values | View individual data point values, display pipeline executions, and open those executions on the Pipeline executions page. |
| Add a chart that was removed | Zoom in | Zoom in |
