Pager Duty Overrides Checker

Usage

1. Create config file config.json

• PAGERDUTY_READ_ONLY_TOKEN is used for reading schedules and checking the overlaps.
• SCHEDULES array can contain one or more SCHEDULE items to check
• every SCHEDULE should have a NOTIFICATIONS to create incident or send message if overlap is found
• SCHEDULE can contain a EXCLUSION_DAYS key, which specifies days (3 letter abb.) in form of object with optional start and end time (hh:mm format UTC TIMEZONE).If start or end is omitted, whole day is considered excluded. Example below represents current weekend on-call setup.

Currently, we only support Slack (SLACK with SLACK_WEBHOOK_URL and CHANNEL) or shorthanded SLACK_WEBHOOK_URL and PagerDuty (PAGERDUTY_TOKEN) notifications.

{
	"PAGERDUTY_API_URL": "https://acme.pagerduty.com/api/v1",
	"PAGERDUTY_READ_ONLY_TOKEN": "33333333333333333333",
	"WEEKS_TO_CHECK": 2,
	"SCHEDULES": [{
		"SCHEDULE": ["PWEVPB6", "PT57OLG"],
		"NOTIFICATIONS": {
		    "SLACK": {
			  "SLACK_WEBHOOK_URL": "http://acme.slack.com/11111",
			  "CHANNEL": "#channel-name"
			}
		}
	}, {
		"SCHEDULE": ["PWEVPB6", "PT57OLA"],
		"NOTIFICATIONS": {
			"PAGERDUTY_TOKEN": "22222222222222222222",
			"SLACK_WEBHOOK_URL": "http://acme.slack.com/11111",
		},
		"EXCLUSION_DAYS": {"Fri": {"start": "14:00", "end": "23:59"}, "Sat": {}, "Sun": {"start": "00:00", "end": "14:00"}}
	}]
}

1. Run command and check:

$ ./bin/pdoverrides check --config config.json

Config schedule IDs passed.
OK

Debug problems

For debugging you can use debug package included in the library:

DEBUG=pagerduty-overrides* ./bin/pdoverrides check -c config.json

Alternatively, you can include the DEBUG variable in the config.json file (esp. for debugging on AWS Lambda).
