Overview

Edge Delta’s Search is powered by the Common Query Language (CQL), a simple and powerful way to get answers from your logs.

Search for Logs

To search for logs you click Logs and select Search.

You can select the Lookback period and the comparison period. The comparison period takes the average of lookback intervals for the given period and this is rendered as the line in the graph:

See Search Logs for more information.

Click the Share button to copy a shortened URL to the clipboard that you can share with others to view the same query. If you have a relative Lookback filter selected, such as the previous 15 minutes, the same relative duration will be shared. This means that someone viewing the shared query will see the previous 15 minutes from the moment they open the query. If you shared a query with a custom lookback period, the same period will be shared. Someone viewing this type of query will view the same log results from that particular time window, for example during a critical outage event.

Download Results

See Add Facets.

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

Group by

You can group the graph by any of the facets listed in the Filter Pane using the Group By option. For example, you may want to see logs with a particular attribute from all sources, and viewed as series on a single graph.

With a group selected you can view the table as a pie chart:

Unique Count

You can view a count of unique dimension values by selecting the dimension in the Unique count by list. For example, 87 pods have generated logs in the past 15 minutes:
