Overview

The Metrics page displays the outputs and values of all metrics ingested and created by Edge Delta, including Kubernetes scraped metrics, metric processing nodes, metric source nodes, and derived metrics.

See Ingest Kubernetes Metrics.

Note: The types of metrics available in the Metrics window will depend on what Input sources you’ve configured for Metrics ingestion. For example, if you have deployed a Kubernetes Metrics Input Node in a particular Agent Tag configuration then you should see the Kubernetes metrics available in the Metric Name dropdown box, such as ed_k8s_metric_container_network_receive_packets. For a complete list of Kubernetes metrics ingested by the Edge Delta agent, please the metrics list.

Metrics

Click Metrics to view the Metrics Explorer and select a metric.

Aggregation transforms raw data into meaningful summaries by applying mathematical operations, which condenses many data points into a single, understandable figure:

  • Sum: Adds up all data points over a defined period or set of records, useful for total measurements like total traffic volume.
  • Average: Computes the mean value of data points, providing a general trend or typical measurement over a dataset.
  • Min and Max: Identify the smallest or largest data point in the set, highlighting extremes, which can indicate unusual events or conditions.
  • Count: Simply tallies the number of records or events, useful for quantifying occurrences like the number of error logs.
  • Median: Finds the middle value in a sorted set of data, offering a robust measure of central tendency that is less affected by outliers.
  • Count Unique: Counts distinct values in a dataset, important for identifying diversity or variety in records, like the number of unique hosts.

Filter Pane

You can filter data using the Filters pane:

  • Fleet
  • Host name
  • Kubernetes, Amazon ECS, and Docker Resource Types

Group by

You can group the graph by any of the facets listed in the Filter Pane using the Group By option. With a group selected you can view the table as a pie chart:

Count By

You can view a count of unique dimension values by selecting Count Unique as the Aggregation Method and by selecting the dimension in the Count by list. For example, 9 hosts have generated an out_items metric in the past 15 minutes.

Add Facet

See Add Facets.

You can select the facet in the Group By list, and you can filter by the facet in the Filters pane.

Create a Monitor

You can create a monitor alert based on the selected filters. Click Create Monitor. Metric Alerts will be available in the Monitors tab in the Edge Delta UI and appear as type metric-alert.
