./multivac/fetch.py [OPTION] [owner/repo]

multivac/fetch.py — download workflow runs GitHub API, workflow run jobs
GitHub API and logs. Result stored in `<owner>/<repo>/workflow_runs` and 
`<owner>/<repo>/workflow_run_jobs` directories in the root of the project.

--branch __branch__

        Branch (all if omitted). To collect data about several branches, use
        this option several times.

--nologs

        Don't download logs

--nostop

        Continue till end or rate limit

--since __N__

        A workflow run list page to start from it. Default: 1

Collect all data about workflow runs and workflow run jobs till the end
of rate limit from repository `tarantool/multivac` branches `master` and
`sample-branch`, but don't collect logs:

./multivac/last_seen.py --branch __branch__ [OPTIONS]

multivac/last_seen.py - generate common report from data collected by 
`multivac/fetch.py` and store it in `output` directory. By default, it
generates a report in CSV format. To start locally, set some value as
'LOG_STORAGE_BUCKET_URL' - uses as a value in result file.

--branch branch

        Generate a report for a certain branch.

--format __[csv|html]__

        Generate a report in CSV format or in HTML format.

--short

        Coalesce 'runs-on' labels by a first word

--repo-path

        owner/repository
        Uses in `fetch.py` result files path, so `last_seen.py` needs it to
        find data for certain repo. Default: 'tarantool/tarantool'. You can
        set only one repo in one sckript start.

Generate a report in the HTML format for branches `master` and
`sample-branch` for repo 'tarantool/multivac':

./multivac/gather_data.py [OPTIONS]

Analyze logs and gather data about all finished jobs and tests which failed.
See the parameters it collects on the
[website](https://www.tarantool.io/en/dev/multivac/gather_data/).

--tests, -t
        Collect data about test failures from test logs. Without this
        option the script will collect data only about workflows.

--format __[csv|json|infuxdb]__

        Store gathered data as `workflows.csv` or `workflows.json` file in
        `output` directory or store data in InfluxDB.

--failure-stats

        Show overall failure statistics.

--watch-failure __failure-type__

        Show detailed statistics about certain type of workflow failure. See
        list of known failure types with `--failure-stats` option.

--latest __N__

        Only take logs from the latest N workflow runs.

--since __N[d|h]__

        Only take logs for jobs started N days or hours ago: Nd for N days
        and Nh for N hours.

--repo-path

        repository (without owner)
        Uses in `fetch.py` result files path, so `gather_data.py` needs it
        to find data for certain repo. Default: 'tarantool/tarantool'.
        You can set only one repo in one sckript start.

Collect data about jobs and tests started a week ago or later in repo 
'tarantool/multivac' (so the fetched JSON and log files stored in the path
./tarantool/multivc), and put this data to InfluxDB:

./multivac/gather_test_data.py [OPTIONS]

Get data about every failed test in the completed jobs and group them by
job ID: test name, test configuration, test number (to unicalize data in
InfluxDB for correct statistic calculation).

--format __[csv|infuxdb]__

        Store gathered data as `tests.json` file in `output` directory or
        store data in InfluxDB. For JSON format - will rewrite file if
        exists.
        JSON example: 

            "8301691934": [
            {
              "name": "box/tx_man.test.lua",
              "configuration": null,
              "test_number": 0
            },
            {
              "name": "replication/qsync_advanced.test.lua",
              "configuration": "vinyl",
              "test_number": 1
            },
            ]

        For InfluxDB, collects job name for tests to make graphics:
            {
            "measurement": test_name,
            "tags": {
                'job_id': job_id,
                'configuration': test['configuration'],
                'job_name': metadata['job_name'],
                'commit_sha': metadata['commit_sha'],
                'test_number': test['test_number']
            },
            "fields": {
                "value": 1
            },
            "time": metadata["started_at"]
            }

--since __N[d|h]__

        Only take logs for jobs started N days or hours ago: Nd for N days
        and Nh for N hours.

Collect data about jobs started a week ago and earlier and put them to the
InfluxDB:
