Which dashboard(s) does it exist in?​

How is it calculated?​

SQL Queries

The following SQL shows how to find the pickup time of a specific PR. DevLake pre-calculates the metric and stores it in table.project_pr_metrics.

SELECT
  pr_pickup_time/60 as 'PR Pickup Time(h)'
FROM
  project_pr_metrics

If you want to measure the monthly trend of PR pickup time in the screenshot below, please run the following SQL in Grafana. 

SELECT 
  DATE_ADD(date(pr.created_date), INTERVAL -DAY(date(pr.created_date))+1 DAY) as time,
  avg(ppm.pr_pickup_time)/60 as 'PR Pickup Time(h)'
FROM 
  pull_requests pr
  JOIN project_pr_metrics ppm ON pr.id = ppm.id
GROUP BY 1
ORDER BY 1

How to improve?​

  1. Use DevLake's dashboard to monitor your delivery progress;
  2. Have a habit to check for hanging PRs regularly;
  3. Set up alerts for your communication tools (e.g. Slack, Lark) when new PRs are issued.
