These scripts are designed to be run via a cron job with the MAILTO variable set to generate an email(or any other notification method) when output occurs.

Output will occur when an IP is added/removed or changed for the service you are checking.

• check_events.sh - Checks events.pagerduty.com for changed IP addressses.

• check_mailservers.sh - Checks acme.pagerduty.com for changed MX record IP addressses. (Used when you utilize an email integrated service and need to whitelist outgoing traffic to PagerDuty)

• check_webhooks.sh - Checks webhooks.pagerduty.com for changed IP addressses.

• check_webhooks_and_alert.sh - Same as check_webhooks.sh but triggers a PagerDuty incident.
