PagerDuty

PagerDuty provides alerting, on-call scheduling, escalation policies and incident tracking to increase uptime of your apps, servers, websites and databases.
Using Crittercism’s PagerDuty integration, whenever a Crittercism alert is triggered, it will automatically trigger an incident in PagerDuty so that customers can take advantage of PagerDuty’s schedule management, alerting, and incident tracking system.
