ma-rmv-stats

Query Massachusetts RMV wait times and publish to Stackdriver as custom metrics.

To run this script on a GCP instance:

Create a new GCP instance.
- All GCP instances, given default permissions, can write custom metrics.
- If you would like to be able to run the example query to verify that everything is working end-to-end, add the "Full" scope for the "Stackdriver Monitoring API". The default scope does not allow querying the MonitoringApi.ListTimeSeries endpoint.
ssh into the instance.

Execute the following:

$ sudo apt-get -y install git python3-pip python3-venv
$ git clone https://github.com/premoxios/ma-rmv-stats.git
$ cd ma-rmv-stats
$ python3 -m venv ./virtualenv
$ source ./virtualenv/bin/activate
$ python3 -m pip install wheel
$ python3 -m pip install -r requirements.txt
$ python3 ma-rmv-stats.py --project_id [PROJECT_ID]

To collect data on a regular schedule via cron, add a crontab entry as, e.g.,

$ sudo sh -c 'echo "2,7,12,17,22,27,32,37,42,47,52,57 * * * * root \
  . /[PATH]/ma-rmv-stats/virtualenv/bin/activate && \
  python /[PATH]/ma-rmv-stats/ma_rmv_stats.py --project_id [PROJECT_ID] >> \
  /var/log/rmv.log" >> /etc/crontab'
