clan has three basic uses
- Writing query results to an text or HTML report suitable for reading.
- Writing query results to a JSON file suitable for further processing.
- Generating an HTML “diff”, or change report, comparing two JSON outputs.
Generating a text report¶
To configure clan, create a YAML data file describing the analytics you want to run:
# Global configuration, only property-id is required title: Commencement report property-id: "53470309" start-date: "2014-06-01" prefix: "/commencement/" # Metrics to report queries: - name: Totals description: Top-level counts metrics: - "ga:pageviews" - "ga:uniquePageviews" - "ga:users" - "ga:sessions" - name: Totals by device category description: Device categories are desktop, tablet and mobile metrics: - "ga:pageviews" - "ga:uniquePageviews" - "ga:users" - "ga:sessions" dimensions: - "ga:deviceCategory" sort: - "-ga:pageviews"
Assuming this configuration is named “configuration.yml”, to produce an HTML report for this configuration you would run the following command.
clan report configuration.yml report.html
For complete documenation of this configuration, see Configuration.
Generating a JSON report¶
Instead of HTML you can output data in a JSON microformat suitable for diffing, archiving, visualization or further processing with other tools:
clan report configuration.yml report.json
Global configuration options, such as start-date can also be specified as command line arguments, allowing you to reuse a YAML configuration file for several projects. When specified, command-line arguments will always take precedence over options defined in the YAML configuration.
clan report --start-date 2014-05-1 --prefix /tshirt/ configuration.yml report.json
You can also convert an HTML report from an existing JSON report:
clan report analytics.json report.html
Generating a text diff¶
If you report on multiple projects using the same analytics, you can use clan to compare their performance:
clan diff a.json b.json diff.html
The values in the diff report columns will be:
- Absolute difference
- Percent change
- Change in percentage points
Generating a JSON diff¶
As with individual reports, diffs can also be saved as JSON for further processing:
clan diff a.json b.json diff.json
