This script monitors our Zendesk and Jira accounts and notifies us in a Slack room when the bug report rates are far enough above the mean rate to have a very high probability of being due to an abnormal event (think a newly introduced bug).

"Far enough above" is given by a Poisson distribution with a certain probability threshold -- if the probability of seeing at least this number of bug reports due to random chance is low enough, we send a notification, because it's likely that this elevated rate is due to a bug.

This uses alertlib (a sub-repo) to talk to Slack. alertlib requires being able to import a file called secrets.py with the contents:

slack_alertlib_webhook_url = "<slack url value>"

The script runs as a cron job on toby; see the aws-config repo for the crontab.
