history of GitLab CI job running times
GitLab CI is nice, but I miss build time trends graphs from Jenkins. So here’s a script that can at least compute some summary information:
$ gitlab-jobs --csv jobs.csv Last 20 successful pipelines of myproject master: ... Summary: build_client min 4.2m, max 7.6m, avg 5.8m, median 5.7m, stdev 1.0m build_docker min 2.7m, max 11.6m, avg 3.5m, median 3.0m, stdev 1.9m build_server min 6.6m, max 12.2m, avg 8.9m, median 8.1m, stdev 1.9m test_robot min 25.4m, max 38.3m, avg 30.0m, median 29.1m, stdev 3.6m unittests_client min 1.1m, max 7.9m, avg 4.1m, median 4.6m, stdev 2.5m unittests_server min 3.5m, max 6.3m, avg 4.9m, median 5.1m, stdev 0.9m overall min 37.4m, max 55.8m, avg 45.6m, median 45.6m, stdev 3.8m Writing jobs.csv...
You can then import the CSV file into a spreadsheet and produce nice charts like
(NB: this chart has the X axis flipped and the Y axis scaled, because that makes more sense to me. The CSV data contains durations in seconds, newest first.)
pip3 install --user gitlab-jobs should take care of everything, just make sure ~/.local/bin is on your $PATH.
Or you may want to use a script installer like pipx (my favourite).
Create a ~/.python-gitlab.cfg like this:
[global] default = mygitlab [mygitlab] url = https://gitlab.example.com/ private_token = ...
You can create a private access token in your GitLab profile settings. It’ll need the “read_api” access scope.
You’ll need a GitLab project ID. By default gitlab-jobs tries to guess it from the ‘origin’ git remote URL, if you’re running it inside a git checkout. Otherwise you’ll have to specify it (either as a number like 1234, or as “group/project”, with the slash between them)
gitlab-jobs --project GROUP/PROJECT ...
