Gathering workflow data

Gathering workflow data

Gathering data about workflow jobs.

Writing options

Gathered data can be written to a CSV or JSON file, configured with --format [csv|json] option. There is no default option and without --format there will be no output file.

$ ./multivac/ --format csv

The resulting output will look like this:

7952018403,fedora_34 (gc64),master,b7cb1421c322d93dc2893ad9e827a5b4d00e265f,success,2022-08-22T12:48:45Z,2022-08-22T12:48:51Z,2022-08-22T12:58:47Z,amd64,['ubuntu-20.04-self-hosted'],ghacts-tarantool-8-16-n5,2.295.0,

Same with JSON:

$ ./multivac/ --format json
  "7918651226": {
    "job_id": 7918651226,
    "job_name": "centos_8 (gc64)",
    "status": "success",
    "queued_at": "2022-08-19T13:01:30Z",
    "started_at": "2022-08-19T13:01:41Z",
    "completed_at": "2022-08-19T13:08:35Z",
    "runner_label": [
    "platform": "amd64",
    "commit_hash": "02fae15a3adb8ea450ebbe3c250a4846cf1cca69",
    "branch": "master",
    "runner_name": "ghacts-shared-8-16-n10",
    "runner_version": "2.295.0"
  "7918651223": {
    "job_id": 7918651223,
    "job_name": "opensuse_15_2 (gc64)",
    "status": "failure",
    "queued_at": "2022-08-19T13:01:30Z",
    "started_at": "2022-08-19T13:01:44Z",
    "completed_at": "2022-08-19T13:08:30Z",
    "runner_label": [
    "platform": "amd64",
    "commit_hash": "02fae15a3adb8ea450ebbe3c250a4846cf1cca69",
    "branch": "master",
    "runner_name": "ghacts-shared-8-16-n3",
    "runner_version": "2.295.0",
    "failure_type": "testrun_test_failed"

Or you can store data in InfluxDB (see InfluxDB connector):

$ multivac/ --format influxdb

Limiting and filtering workflows

Workflows which were skipped or cancelled won’t be processed.

To gather data from a number of most recent workflows, use --latest:

$ ./multivac/ --latest 1000

To gather data for the last N days or N hours, use --since:

$ # see data for the last week (7 days)
$ ./multivac/ --since 7d
$ # see data for the last 12 hours
$ ./multivac/ --since 12h

Detecting workflow failure reasons

Multivac can detect types of workflow failures and calculate detailed statistics. Detailed description of known failure reasons can be found in Types of detected workflow failures.

$ ./multivac/ --latest 1000 --failure-stats

total 20
package_building_error 5
unknown 4
testrun_test_failed 3
telegram_bot_error 2
integration_vshard_test_failed 1
luajit_error 1
testrun_test_hung 1
git_repo_access_error 1
dependency_autoreconf 1
tap_test_failed 1

Command --watch-failure name will return a list of jobs where the named failure has been detected, along with the links to workflow runs on GitHub and matching log lines:

$ ./multivac/ --latest 1000 --watch-failure testrun_test_failed
7008229080  memtx_allocator_based_on_malloc
                        2022-06-22T16:27:25.7389940Z * fail: 1
6936376158  osx_12
                        2022-06-17T13:11:18.6461930Z * fail: 1
6933185565  fedora_34 (gc64)
                        2022-06-17T09:24:50.6543965Z * fail: 1

This is useful when working with yet undetected failure reasons:

$ ./multivac/ --latest 1000 --watch-failure unknown
